| 1 | Temporal and spatial variations of the active layer along the Qinghai-Tibet Highway in a permafrost region显示文摘Using monitored active layer thickness(ALT) and environmental variables of 10 observation fields along the Qinghai-Tibet Highway in permafrost region of the Qinghai-Tibetan Plateau(QTP),a model for ALT estimation was developed.The temporal and spatial characteristics of the ALT were also analyzed.The results showed that in the past 30 years ALT in the study region increased at a rate of 1.33 cm a-1.Temperatures at the upper limit of permafrost and at 50 cm depth,along with soil cumulative temperature at 5 cm depth also exhibited a rising trend.Soil heat flux increased at a rate of 0.1 Wm-2 a-1.All the above changes demonstrated that the degradation of permafrost happened in the study region on the QTP.The initial thawing date of active layer was advanced,while the initial freezing date was delayed.The number of thawing days increased to a rate of 1.18 da-1.The variations of active layer were closely related to the permafrost type,altitude,underlying surface type and soil composition.The variations were more evident in cold permafrost region than in warm permafrost region,in high-altitude region than in low-altitude region,in alpine meadow region than in alpine steppe region;and in fine-grained soil region than in coarse-grained soil region. | LI Ren ZHAO Lin DING YongJian WU TongHua XIAO Yao DU ErJi LIU GuangYue QIAO YongPing | 2012 | Chinese Science Bulletin2012，57，35： | 51 |
| 2 | Cryospheric Science: research framework and disciplinary system显示文摘Cryospheric changes and their impacts have received increasing concern, extending the research to include the interactions between earth spheres and the impacts of and social adaptation to cryospheric changes. As a result, Cryospheric Science is rapidly developing. However, the research framework of Cryospheric Science has not completely been set up, and the intension and extension of Cryospheric Science are unclear.Following a literature review, the research framework for Cryospheric Science and the discipline components are analysed in this paper. We consider that Cryospheric Science is an inevitable product of international research on the earth and environmental changes as well as on human sustainable development. It will not only strengthen the linkage between the cryosphere and other earth spheres by deepening traditional research areas, but will also bring more focus on the critical roles of the cryosphere in interactions between earth spheres, and will enhance the relationship between cryospheric change and climate, ecology, hydrology, surface environment and sustainable development. The disciplinary tree of Cryospheric Science is developed following the mainstream of change-impacts adaptation. The disciplines of Cryospheric Science were teased out against characteristics of traditional branches and the developing interdisciplinary branches of cryosphere elements, which will provide reference to Cryospheric Science as it systematically grows to maturity. | Dahe Qin Yongjian Ding Cunde Xiao Shichang Kang Jianwen Ren Jianping Yang Shiqiang Zhang | 2018 | National Science Review2018，5，2： | 42 |
| 3 | Global warming weakening the inherent stability of glaciers and permafrost显示文摘The Cryosphere has been undergoing a worldwide retreat, as seen in the decrease in the areal extent and volume of glaciers and in the areal extent of permafrost. This paper presents a systematic examination of the inherent stability changes of glaciers and permafrost caused by warming. Various study results suggest that over the past 30 years, the internal temperature of glaciers and permafrost exhibits an overall accelerating warming trend. The warming rate peaked in the mid-2000s and slowed slightly for several years afterward. In recent years, however, the warming rate has seemed to pick up again. The warming of glaciers and permafrost has exerted great impact on their stability, displayed as intensified melting,increased glacier surging, enlargement of supraglacial lakes, and increased permafrost degradation.Even without a future temperature increase, some glaciers will continue to shrink, and the number of surging glaciers will increase. The transition from low-temperature to high-temperature permafrost is a noticeable warning sign of a comprehensive degradation of permafrost. These results indicate that‘‘warming' glaciers and permafrost will exert significant impacts on the hydrology, ecology, and stability of engineering in cold regions. | Yongjian Ding Shiqiang Zhang Lin Zhao Zhongqin Li Shichang Kang | 2019 | Science Bulletin2019，64，4： | 37 |
| 4 | Glacier changes during the last forty years in the Tarim Interior River basin,northwest China显示文摘By comparing digitized glacier outlines from the Chinese Glacier Inventory (CGI) during the 1960s-1970s and Landsat Enhance Thematic Mapper (ETM+) images from 1999 to 2001, we investigated changes for about 7665 alpine glaciers among 11665 glaciers in seven sub-basins of the Tarim Interior River basin (TIRB). The results showed that the total glacier area was reduced by 3.3% from the 1960s/ 1970s to 1999/2001 and area losses for 1-5 km2 glaciers accounted for 48.3% of the total glacier area loss in the TIRB. However, the glacier area reductions varied from 0.7% to 7.9% among the seven sub-basins of the TIRB during the study period. The glacier area changing with altitude showed that the maximum contribution of area shrinkage occurred at 4900-5400 m. Data from 25 meteorological stations in the TIRB showed increases in both the annual mean air temperature and annual precipitation during 1960-2000. This indicates that the glacier shrinkage in the TIRB over the last 40 years was largely due to regional climate warming that enhanced glacier ablation and overcame the effects of increased precipitation on the glacier mass balance. | Donghui Shangguan Shiyin Liu Yongjian Ding Lianfu Ding Junli Xu Li Jing | 2009 | Progress in Natural Science:Materials International2009，19，6： | 26 |
| 5 | Contributions of climate and human activities to changes in runoff of the Yellow and Yangtze rivers from 1950 to 2008显示文摘Runoffs in the Yellow River and Yangtze River basins,China,have been changing constantly during the last half century.In this paper,data from eight river gauging stations and 529 meteorological stations,inside and adjacent to the study basins,were analyzed and compared to quantify the hydrological processes involved,and to evaluate the role of human activities in changing river discharges.The Inverse Distance Weighted(IDW)interpolation method was used to obtain climatic data coverage from station observations.According to the runoff coefficient equation,the effect of human activities and climate can be expressed by changes in runoff coefficients and changes in precipitation,respectively.Annual runoff coefficients were calculated for the period 1950-2008,according to the correlation between respective hydrological series and regional precipitation.Annual precipitation showed no obvious trend in the upper reaches of the Yellow River but a marked downward trend in the middle and downstream reaches,with declines of 8.8 and 9.8 mm/10 a,respectively.All annual runoff series for the Yellow River basin showed a significant downward trend.Runoff declined by about 7.8 mm/10 a at Sanmenxia and 10.8 mm/10 a at Lijin.The series results indicated that an abrupt change occurred in the late 1980s to early 1990s.The trend of correlations between annual runoff and precipitation decreased significantly at the Yellow River stations,with rates ranging from 0.013/10 a to 0.019/10 a.For the hydrologic series,all precipitation series showed a downward trend in the Yangtze River basin with declines ranging from about 24.7 mm/10 a at Cuntan to 18.2 mm/10 a at Datong.Annual runoff series for the upper reaches of the Yangtze River decreased significantly,at rates ranging from 9.9 to 7.2 mm/10 a.In the middle and lower reaches,the runoff series showed no significant trend,with rates of change ranging from 2.1 to 2.9 mm/10 a.Human activities had the greatest influence on changes in the hydrological series of runoff,regardless of whether the effect was negative or positive.During 1970-2008,human activities contributed to 83% of the reduction in runoff in the Yellow River basin,and to 71% of the increase in runoff in the Yangtze River basin.Moreover,the impacts of human activities across the entire basin increased over time.In the 2000s,the impact of human activities exceeded that of climate change and was responsible for 84% of the decrease and 73% of the increase in runoff in the Yellow River and Yangtze River basins,respectively.The average annual runoff from 1980 to 2008 fell by about 97%,83%,83%,and 91%,compared with 1951-1969,at the Yellow River stations Lanzhou,Sanmenxia,Huayuankou and Lijin,respectively.Most of the reduction in runoff was caused by human activities.Changes in precipitation also caused reductions in runoff of about 3%,17%,17%,and 9% at these four stations,respectively.Falling precipitation rates were the main explanation for runoff changes at the Yangtze River stations Cuntan,Yichang,Hankou,and Datong,causing reductions in runoff of 89%,74%,43%,and 35%,respectively.Underlying surface changes caused decreases in runoff in the Yellow River basin and increases in runoff in the Yangtze River basin.Runoff decreased in arid areas as a result of increased water usage,but increased in humid and sub-humid areas as a result of land reclamation and mass urbanization leading to decreases in evaporation and infiltration. | WANG Yan DING YongJian YE BaiSheng LIU FengJing WANG Jie WANG Jie | 2013 | Science China Earth Sciences2013，56，8： | 21 |
| 6 | Eco-environment range in the source regions of the Yangtze and Yellow rivers显示文摘Based on geographical and hydrological extents delimited, four principles are identified, as the bases for delineating the ranges of the source regions of the Yangtze and Yellow rivers in the paper. According to the comprehensive analysis of topographical characteristics, climate conditions, vegetation distribution and hydrological features, the source region ranges for eco-environmental study are defined. The eastern boundary point is Dari hydrological station in the upper reach of the Yellow River. The watershed above Dari hydrological station is the source region of the Yellow River which drains an area of 4.49×10 4 km 2 . Natural environment is characterized by the major topographical types of plateau lakes and marshland, gentle landforms, alpine cold semi-arid climate, and steppe and meadow vegetation in the source region of the Yellow River. The eastern boundary point is the convergent site of the Nieqiaqu and the Tongtian River in the upstream of the Yangtze River. The watershed above the convergent site is the source region of the Yangtze River, with a watershed area of 12.24×10 4 km 2 . Hills and alpine plain topography, gentle terrain, alpine cold arid and semi-arid climate, and alpine cold grassland and meadow are natural conditions in the source region of the Yangtze River. | DING Yongjian,YANG Jianping,LIU Shiyin,CHEN Rensheng,WANG Genxu,SHEN Yongping,WANG Jian,XIE Changwei,ZHANG Shiqing(Cold and Arid Regions Environmental and Engineering Research Institute, CAS, Lanzhou 730000, China) | 2003 | Journal of Geographical Sciences2003，13，2： | 18 |

| 8 | Toward an improved data stewardship and service for environmental and ecological science data in West China显示文摘Sharing of scientific data can help scientific research to flourish and facilitate more widespread use of scientific data for the benefit of society.The Environmental and Ecological Science Data Center for West China(WestDC),sponsored by the National Natural Science Foundation of China(NSFC),aims to collect,manage,integrate,and disseminate environmental and ecological data from western China.It also aims to provide a long-term data service for multidisciplinary research within NSFC’s‘‘Environment and Ecology of West China Research Plan’’(NSFC West Plan).An integrated platform has been developed by the WestDC,and this has the function of data sharing,acting as a knowledge repository.Major data sets developed by the WestDC include basic geographic data,the regionalization of global data set for China,scientific data for cold and arid regions in China,scientific data for the cryosphere in countries that neighbor China,data relating to the inland river basins in northwestern China,and data submitted by the NSFC West Plan projects.In compliance with the‘‘full and open’’data sharing policy,most data in the WestDC can be accessed online.Highlights include detailed data documentation,the integration of data with bibliographic knowledge,data publishing,and data reference. | Xin Li Zhuotong Nan Guodong Cheng Yongjian Ding Lizong Wu Liangxu Wang Jian Wang Youhua Ran Hongxing Li Xiaoduo Pan Zhongming Zhu | 2011 | International Journal of Digital Earth2011，4，4： | 11 |
| 9 | Stable Isotopes in Precipitation in Xilin River Basin,Northern China and Their Implications显示文摘Under the increasing pressure of water shortage and steppe degradation,information on the hydrological cycle in steppe region in Inner Mongolia,China is urgently needed.An intensive investigation of the temporal variations ofδD andδ1 8O in precipitation was conducted in 2007-2008 in the Xilin River Basin,Inner Mongolia in the northern China.TheδD andδ1 8O values for 54 precipitation samples range from+1.1‰to-34.7‰and-3.0‰to -269‰,respectively.This wide range indicates that stable isotopes in precipitation are primarily controlled by different condensation mechanisms as a function of air temperature and varying sources of vapor.The relationship between δD andδ1 8 O defined a well constrained line given by δD =7.89 δ18O+9.5,which is nearly identical to the Meteoric Water Line in the northern China.The temperature effect is clearly displayed in this area.The results of backward tra- jectory of each precipitation day show that the vapor of the precipitation in cold season(October to March)mainly originates from the west while the moisture source is more complicated in warm season(April to September).A light precipitation amount effect existes at the precipitation event scale in this area.The vapor source of precipitation with higher d-excesses are mainly from the west wind or neighboring inland area and precipitation with lower d-excesses from a monsoon source from the southeastern China. | WU Jinkui DING Yongjian YE Baisheng YANG Qiyue HOU Dianjiong XUE Liyang | 2012 | Chinese Geographical Science2012，22，5： | 9 |
| 10 | Initial estimate of the contribution of cryospheric change in China to sea level rise显示文摘Recent studies have shown that cryospheric melting is becoming the dominant factor responsible for sea level rise,and that the melt-water from mountain glaciers and ice caps has comprised the majority of the cryospheric contribution since 2003.Analysis of the estimations of cryospheric melt-water and precipitation in glacier regions indicated that the potential contribution of the cryosphere in China is 0.14 to 0.16 mm a–1,of which approximately 0.12 mm a–1 is from glaciers.The contribution of glaciers in the outflow river basins is about 0.07 mm a–1,accounting for 6.4%of the total from global glaciers and ice caps. | REN JiaWen YE BaiSheng DING YongJian LIU ShiYin | 2011 | Chinese Science Bulletin2011，56，16： | 9 |
| 11 | The Impacts of Permafrost Change on NPP and Implications:A Case of the Source Regions of Yangtze and Yellow Rivers显示文摘This paper studies the relationship between net primary productivity (NPP) and annual average air temperature (GT) at 0cm above ground in permafrost regions by using revised Chikugo NPP model,cubic spline interpolating functions,and non-linear regression methods.The source regions of the Yangtze and Yellow Rivers were selected as the research areas.Results illustrate that:(1) There is significant non-linear relationship between NPP and GT in various typical years;(2) The maximum value of NPP is 6.17,5.87,7.73,and 5.41 DM·t·hm-2 ·a-1 respectively,and the corresponding GT is 7.1,10.0,21.2,and 8.9 o C respectively in 1980,1990,2000 and 2007;(3) In 1980,the sensitivity of NPP to GT is higher than in 1990,2000 and 2007.This tendency shows that the NPP presents change from fluctuation to an adaptation process over time;(4) During 1980~2007,the accumulated NPP was reduced to 8.05,and the corresponding carrying capacity of theoretical livestock reduced by 11%;(5) The shape of the demonstration region of ecological compensation system,livelihood support system,and science appraisal system in the source regions of Yangtze and Yellow Rivers are an important research for increasing the adaptation capacity and balancing protection and development. | FANG Yiping QIN Dahe DING Yongjian YANG Jianping XU Keyan | 2011 | Journal of Mountain Science2011，8，3： | 9 |
| 12 | Integrated modeling environment and a preliminary application on the Heihe River Basin, China显示文摘Environmental and water issues are essentially complex interdisciplinary problems. Multiple models from different disciplines are usually integrated to solve those problems. Integrated modeling environment is an effective technical approach to model integration. Although a number of modeling environments worldwide are available, they cannot meet current challenges faced. Their old-fashion designs and original development purposes constrain their possible applications to the domain of hydrologic or land surface modeling. One of the challenges is that we intend to link knowledge database or ontology system to the modeling environment in order to make the modeling support more intelligent and powerful. In this paper, we designed and implemented an integrated modeling environment (HIME) for hydrological and land surface modeling purpose in a much extendable, efficient and easy use manner. With such design, a physical process was implemented as a module, or component. A new model can be generated in an intuitive way by linking module icons together and establishing their relationships. Following an introduction to the overall architecture, the designs for module linkage and data transfer between modules are described in details. Using XML based meta-information, modules in either source codes or binary form can be utilized by the environment. As a demonstration, with the help of HIME, we replaced the evaporation module of TOPMODEL with the evapotranspiration module from the Noah land surface model which explicitly accounts for vegetation transpiration. This example showed the effectiveness and efficiency of the modeling environment on model integration. | NAN ZhuoTong SHU LeLe ZHAO YanBo LI Xin DING YongJian | 2011 | Science China(Technological Sciences)2011，54，8： | 8 |
| 13 | Regional difference of annual precipitation and discharge variation over west China during the last 50 years显示文摘Using annual precipitation and discharge data measured in the past five decades,this paper analyzed the regional differences over west China in terms of climate and discharge variations,and investigated the relationship between the regional characteristics and the activities of South and East Asian sum-mer monsoon. Results revealed that the precipitation and discharge in the upper reaches of the Yellow River (Central West China) have a negative correlation with those in Xinjiang (northwest China) and the Yarlung Zangbo River (the upper reaches of the Brahmaputra Rive,southwest China) regions. The geographical patterns of precipitation and discharge variations are different over west China,i.e. the regional climate displays the alteration of dry-wet-dry or wet-dry-wet from north to south in west China. The negative correlation of annual discharges between Xinjiang and the upper reaches of the Yellow River is found statistically significant in the decadal scale,and that between the Yarlung Zangbo River and the upper reaches of the Yellow River is found active in the interannual scale. The regional char-acteristics indicate that the discharge/precipitation variations in the upper reaches of the Yellow River are dominated by the East Asian summer monsoon while their variations in Xinjiang are affected by both the west wind and East Asian summer monsoon. | DING YongJian YE BaiSheng HAN TianDing SHEN YongPing LIU ShiYin | 2007 | Science China Earth Sciences2007，50，6： | 7 |
| 14 | Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes. | Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li | 2020 | Cell Research2020，30，2： | 7 |
| 15 | Understanding the impact of mountain landscapes on water balance in the upper Heihe River watershed in northwestern China显示文摘Estimating the impact of mountain landscape on hydrology or water balance is essential for the sustainable development strategies of water resources.Specifically,understanding how the change of each landscape influences hydrological components will greatly improve the predictability of hydrological responses to mountain landscape changes and thus can help the government make sounder decisions.In the paper,we used the VIC(Variable Infiltration Capacity)model to conduct hydrological modeling in the upper Heihe River watershed,along with a frozen-soil module and a glacier melting module to improve the simulation.The improved model performed satisfactorily.We concluded that there are differences in the runoff generation of mountain landscape both in space and time.About 50% of the total runoff at the catchment outlet were generated in mid-mountain zone(2,900-4,000 m asl),and water was mainly consumed in low mountain region(1,700-2,900 m asl)because of the higher requirements of trees and grasses.The runoff coefficient was 0.37 in the upper Heihe River watershed.Barren landscape produced the largest runoff yields(52.46% of the total runoff)in the upper Heihe River watershed,followed by grassland(34.15%),shrub(9.02%),glacier(3.57%),and forest(0.49%).In order to simulate the impact of landscape change on hydrological components,three landscape change scenarios were designed in the study.Scenario 1,2 and 3 were to convert all shady slope landscapes at 2,000-3,300 m,2,000-3,700 m,and 2,000-4,000 m asl respectively to forest lands,with forest coverage rate increased to 12.4%,28.5% and 42.0%,respectively.The runoff at the catchment outlet correspondingly declined by 3.5%,13.1% and 24.2% under the three scenarios.The forest landscape is very important in water conservation as it reduced the flood peak and increased the base flow.The mountains as 'water towers' play important roles in water resources generation and the impact of mountain landscapes on hydrology is significant. | Jia QIN YongJian DING JinKui WU MingJie GAO ShuHua YI ChuanCheng ZHAO BaiSheng YE Man LI ShengXia WANG | 2013 | Journal of Arid Land2013，5，3： | 6 |
| 16 | Changes in physical features of Glacier No. 1 of the Tianshan Mountains in response to climate change显示文摘This study analyzes the changes in glacier zones and snow composition of Glacier No.1 in the Tianshan Mountains of China since 1961,and their possible relations with climate.It is found that precipitation dominated the snow composition and that air temperature and precipitation controlled the distribution of glacier zones,but interannual change in precipitation had a relatively large effect on glacier zones and snow composition during 1963–1981 (P10) and 1963–1989 (P11).However,during 1982–2007 (P20) and 1990–2007 (P21),the air temperature rise (0.57°C/10 a for P20,0.76°C/10 a for P21) was more influential than the precipitation increase (51.3 mm/10 a for P20),and air temperature was principally responsible for the evolution of glacier zones and snow composition most probably resulting from recent climate warming. | LI XiangYing DING YongJian YE BaiSheng HAN TianDing | 2011 | Chinese Science Bulletin2011，56，26： | 6 |
| 17 | Adaptation Management of Mountain Tourism Service: The Case of the Source Regions of the Yangtze and Yellow River显示文摘Mountain areas are often rich in ecological diversity and recreational opportunities. Mountain tourism is thought to be an effective and important means for maintaining and expanding rural economies and, thus, improving the living conditions of rural societies. As mountain tourism service research is a professional field with several disciplines involved, a multi-disciplinary management platform is needed and it facilitates participation in sustainable mountain development by diverse stakeholders. With the source regions of the Yangtze and the Yellow River as a case study, this paper presents a conceptual framework for an adaptation management of mountain tourism services according to technical, policy, social and economic dimensions. The framework is based on a vulnerability assessment of mountain ecosystems, and can serve as a reference for the development of tourism service in other mountain areas. | FANG Yiping QIN Dahe DING Yongjian YANG Jianping | 2009 | Journal of Mountain Science2009，6，3： | 6 |
| 18 | A review of the interaction between the cryosphere and atmosphere显示文摘The interaction between the cryosphere and atmosphere is an essential and extremely sensitive mutual action process on the earth.Due to global warming and the cryospheric melting,more and more attention has been paid to the interaction process between the cryosphere and atmosphere,especially the feedback of the cryosphere change to the atmosphere.A comprehensive review of the studies on the interaction between the cryosphere and atmosphere is conducted from two aspects:(1)effects of climate change on the cryosphere or responses of the cryosphere to climate change;and(2)feedback of the cryosphere change to the climate.The response of the cryosphere to climate change is lagging.Such a lagging and cumulative effect of temperature rise within the cryosphere have resulted in a rapid change in the cryosphere in the 21st century,and its impacts have become more significant.The feedback from cryosphere change on the climate are omnifarious.Among them,the effects of sea ice loss and snow cover change,especially the Arctic sea ice loss and the Northern Hemisphere snow cover change,are the most prominent.The Arctic amplification(AA)associated with sea ice feedback is disturbing,and the feedback generated by the effect of temperature rise on snow properties in the Northern Hemisphere is also of great concern.There are growing evidence of the impact of the Arctic cryosphere melting on mid-latitude weather and climate.Weakened storm troughs,steered jet stream and amplified planetary waves associated with energy propagation become the key to explaining the links between Arctic cryosphere change and atmospheric circulation.There is still a great deal of uncertainty about how cryosphere change affects the weather and climate through different atmospheric circulation processes at different spatial and temporal scales due to observation and simulation problems. | YongJian Ding JianPing Yang ShengXia Wang YaPing Chang | 2020 | Research in Cold and Arid Regions2020，12，6： | 4 |
| 19 | Important progress on the use of isotope techniques and methods in catchment hydrology显示文摘The use of isotope techniques and methods in catchment hydrology in the last 50 years has generated two major types of progress: (1) Assessment of the temporal variations of the major stocks and flows of water in catchments, from which the estimation of wa-ter residence times is introduced in this paper. (2) Assessment of catchment hydrologic processes, in which the interactions be-tween different waters, hydrographical separation, and bio-geochemical process are described by using isotopes tracers. Future progress on isotope techniques and methods in hydrology is toward the understanding of the hydrological process in large river basins. Much potential also waits realization in terms of how isotope information may be used to calibrate and test distributed rainfall-runoff models and regarding aid in the quantification of sustainable water resources management. | JinKui Wu 1,2, YongJian Ding 1, BaiSheng Ye 1, QiYue Yang 3, Zhi Wei 1 1.

| 20 | The hydrological linkage of mountains and plains in the arid region of northwest China显示文摘Mountain regions supply a large amount of fresh water for the people in arid and semiarid regions, however, there is great uncertainty of the water quantification from mountains to lower areas. In order to assess the hydrological significance of mountains and the hydrological linkage of mountains and plains, the measured and simulated hydrological data of the arid region in northwest China were used in the present research which followed a catchment-based approach. Firstly, the Heihe River Basin, a well-documented area, was selected as a specific watershed to reveal the hydrological relationship between highlands (mountains) and lowlands (plains); and then, the significance and disproportion of mountain runoff of 8 river basins as cases in the arid region of northwest China were analyzed and compared following the above analysis. The results of the study showed that the proportion of mountain runoff in total basinal runoff (PMR) of most rivers is above 50%. The PMR are between 50%-95% in the rivers originated in the northern slope of the Tianshan Mountains where the aqueous vapor is relatively sufficient. And that, almost all the flow of the rivers originating from the Qilian Mountains, the southern slope of the Tianshan Mountains, and the northern slope of the Kunlun Mountains come from mountain regions. Also the PMR gradually increases from west to east in northwest China. The hydrological significance and disproportion of mountains water in the arid region of northwest China were given a systematic and thorough assessment, and the results could give potential guides for the scientific utilization of water resources in these regional areas for relieving the more and more serious shortage of water resources due to climate warming and population expansion. | QIN Jia DING YongJian YANG GuoJing | 2013 | Chinese Science Bulletin2013，58，25： | 3 |
