| 1 | A MULTISCALE SOIL LOSS EVALUATION INDEX显示文摘Exploring the relationships between land use and soil erosion at different scales is a fron-tier research field and a hot spot topic in contempo-rary physical geography. Based on the scale-pattern-process theory in landscape ecology and with consideration of such influential factors as land use, topography, soil and rainfall, this paper ap-plies the scale transition method to establishing a soil loss evaluation index at different scales and puts forward a research path and methodology for mul-tiscale soil loss evaluation indices. The multiscale soil loss evaluation index is applied to the evaluation of relationships between land use and soil erosion and the research of soil erosion evaluation at multiple scales. It provides a new method for optimizing the design of regional land use patterns and integrated multiscale research. | FU Bojie ZHAO Wenwu CHEN Liding Lü Yihe WANG De | 2006 | Chinese Science Bulletin2006，51，4： | 22 |
| 2 | Recent area and ice volume change of Kangwure Glacier in the middle of Himalayas显示文摘This paper calculated and evaluated the area and ice volume changes of Kangwure Glacier in Mt.Xixiabangma,middle of Himalayas in the past 3 decades,based on the field survey of glacier boundary position by differential GPS and glacier depth by Ground Penetrating Radar(GPR),together with the topographic map and remote sense data.The studied data showed that the Kangwure Glacier has experienced significant mass deficit since the 1970s,with 34.2%of area loss,48.2%ofice volume loss and 7.5 m of average thickness decrease.This result revealed that the ice volume loss of Himalayan glaciers was more serious than expected.Analysis of meteorological data from two weather stations in the region of Mt.Xixiabangma,shows that the air temperature of this region has risen from the middle of the 20th century to the beginning of the 21st century.Significant retreat of Himalayas glacier driven by climatic warming will have a remarkable impact on hydrology and ecosystem. | MA LingLong TIAN LiDe PU JianChen WANG PengLing | 2010 | Chinese Science Bulletin2010，55，20： | 17 |
| 3 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |
| 4 | Seasonal variations of stable isotope in precipitation and moisture transport at Yushu,eastern Tibetan Plateau显示文摘Precipitation δ 18O at Yushu, eastern Tibetan Plateau, shows strong fluctuation and lack of clear seasonality. The seasonal pattern of precipitation stable isotope at Yushu is apparently different from either that of the southwest monsoon region to the south or that of the inland region to the north. This different seasonal pattern probably reflects the shift of different moisture sources. In this paper, we present the spatial comparison of the seasonal patterns of precipitation δ 18O, and calculate the moisture transport flux by using the NCAR/NCEP reanalysis data. This allows us to discuss the relation between moisture transport flux and precipitation δ 18O. This study shows that both the southwest monsoon from south and inland air mass transport from north affected the seasonal precipitation δ 18O at Yushu, eastern Tibetan Plateau. Southwest monsoon brings the main part of the moisture, but southwest transport flux is weaker than in the southern part of the Tibetan Plateau. However, contribution of the inland moisture from north or local evaporation moisture is enhanced. The combined effect is the strong fluctuation of summer precipitation δ 18O at Yushu and comparatively poor seasonality. | TIAN LiDe MA LingLong YU WuSheng LIU ZhongFang YIN ChangLiang ZHAO ZhongPing TANG Wei WANG Yu | 2008 | Science China Earth Sciences2008，51，8： | 9 |
| 5 | Isotopic composition of atmospheric water vapor before and after the monsoon's end in the Nagqu River Basin显示文摘Atmospheric water vapor samples were col-lected in the Nagqu River Basin in the middle of Tibetan Plateau between August and October in 2004. Results show that there exist some fluctuations of the δ 18O of atmospheric water vapor, especially before and after the monsoon’s end. Moreover, the variety trend of the δ 18O of atmospheric water vapor inverse correlates with that of dew point. Precipitation events make an important effect upon the variation of δ 18O of atmospheric water vapor. During the whole sampling pe-riod, the δ 18O values of atmospheric water vapor are low while precipitation events occurred. The moisture origins also contribute to the variation of δ 18O of atmospheric water vapor. The oceanic moisture transported by the southwest monsoon results in lower δ18O of atmospheric water vapor in the Nagqu River Basin. Compared with the influence of the oceanic moisture, the δ 18O values, however, appear high re-sulting from the effect of the continental air mass in this re-gion. | YU Wusheng YAO Tandong TIAN Lide WANG Yu YIN Changliang | 2005 | Chinese Science Bulletin2005，50，23： | 7 |
| 6 | A new type of ice formation zone found in the Himalayas显示文摘Ice formation was studied on the Dasuopu Glacier located in the Mount Xixabangma (28°23’ N, 85°43’E) in the Himalayas. Snow pits and shallow ice cores are analyzed to reveal ice formation process. The results show that the ice formation process, or in other words, the process of densitification, on the col (7 000 m a.s.l. ) of the Dasuopu Glacier is a stable, slow and gradual process. The snow-ice transformation on the glacier is estimated to be 30—40 m below the surface. The temperature on the Dasuopu Glacier is very low (~ - 14℃ at 10 m) and similar to that in polar type ice cap. We,therefore, speculate that the process of snow-ice transformation is undertaken under snow pressure,and that there is a percolation zone on the Dasuopu Glacier. The high altitude of the col and monsoon snow fall accompnied by heavy cloud and high albedo favorite the percolation zone formation. | Tandong Yao Jianchen Pu Ninlian Wang Lide Tian | 1999 | Chinese Science Bulletin1999，44，5： | 7 |
| 7 | Effects of riparian vegetation patterns on the distribution and potential loss of soil nutrients: a case study of the Wenyu River in Beijing显示文摘一个河边的生态系统是在一条河隧道和陆上的生态系统之间的一个生态的转变地区。河边的生态系统在维持溪流健康和银行稳定起一个重要作用。因为人的活动,河边的植被的类型沿着 Wenyu 河极大地变化了。这研究由于土壤营养素损失在水污染上检验河边的植被模式的影响。到高地的来自河隧道的四个河边的植被模式被选择为这研究的焦点:草地,农田,草地农田,和 grassland-manmade 草坪。沿着植被模式和滋养的损失的潜在的风险的土壤营养素的不同分布被观察并且比较。结果证明河边的农田有全部的氮(TN ) 的最低价值,全部的磷(TP ) ,可得到的氮(一) ,可得到的磷(AP ) ,和有机物(OM ) ,但是它有最高的土壤体积密度(BD ) 。土壤 TN 的分布, TP,一, AP,和 OM 为河边的农田向河隧道从高地展出了一个衰退趋势,而一个不同趋势为河边的草地被观察。草地农田和 grassland-manmade 草坪的植被模式证明在更低的斜坡的草地有更多的营养素和 OM,但是在上面的斜坡比农田或 manmade 草坪降低土壤 BD。那么,降低斜坡的草地可以从高地拦截并且渗透表面流量。降低斜坡的草地有土壤 TN 的高水平, TP,一,并且 AP,并且因此,它可以成为滋养的损失的新来源。我们的结果建议河边的植被的管理应该被改进,特别地在浓密地占据的区域,到控制土壤侵蚀和河污染。 | Erhui GUO Liding CHEN Ranhao SUN Zhaoming WANG | 2015 | Frontiers of Environmental Science & Engineering2015，9，2： | 6 |
| 8 | Static Schedule Generation for Time-Triggered Ethernet Based on Fuzzy Particle Swarm Optimization显示文摘In time-triggered ethernet(TTEthernet),designing and optimizing the static scheduling of TT messages to improve the real-time performance of the whole network control system is important.When there is a high load on TTEthernet network communication,the conventional static scheduling policy introduces certain problems,such as increased packet loss rate,load imbalance,and transmission delay.Meanwhile,basic artificial intelligence algorithms generally features convergence within only a few steps,leading to higher probability to fall into a local optimal solution.To realize these targets,Fuzzy particle swarm optimization(FPSO)based on population diversity is established.By combining Particle swarm optimization(PSO)with a fuzzy algorithm,setting the adjustment of the inertia weight and the regulation of the mutation factor as the controlled variables of the Fuzzy logic controller(FLC),and adjusting the FLC inference rules,a novel static schedule generation for TTEthernet is proposed.Simulation results prove that,compared to the conventional rate-monotonic scheduling algorithm and the PSO algorithm,FPSO has a strong global search capability when the communication of the TTEthernet system is in a high-load state.FPSO improves the load balancing of the network and reduces the transmission delay of TT message packets.FPSO shows excellent ability to optimize scheduling tables and guarantee the real-time performance of the TTEthernet system. | CHEN Huang WANG Lide SHEN Ping DI Jun | 2019 | Chinese Journal of Electronics2019，28，6： | 5 |
| 9 | Occurrence, spatial distribution and ecological risks of antibiotics in soil in urban agglomeration显示文摘Antibiotics in soil environment are regarded as emerging pollutants and have introduced increasing risks to soil ecosystem and human health in rapid urbanization areas. Identifying the occurrence and spatial variability of antibiotics in soils is an urgent issue in sustaining soil security. In this study, antibiotics in soils were investigated and analyzed in BeijingTianjin-Hebei urban agglomeration. The occurrence, spatial distribution, and related affecting factors of antibiotics in soils were identified and ecological risks of antibiotics in soil environment were assessed. Results showed that(1) The mean concentration of soil antibiotics in Beijing-Tianjin-Hebei urban agglomeration was 21.79 μg/kg. Land use substantially affected the occurrence and concentration of antibiotics in soils. Concentrations of antibiotics in cropland and orchard soils were 2-3 times higher than the other land use types.(2)The concentrations of antibiotics in soils in Beijing-Tianjin-Hebei urban agglomeration presented a spatial pattern of high values in southeast, and low values in northwest. Spatial variability of antibiotics in soils was closely related to the application of organic fertilizer and wastewater irrigation as well as topographical features. Furthermore, soil properties and land management policy had substantial influences on soil antibiotics, and soil heavy metals may aggravate the accumulation of antibiotics in soils.(3) Ecological risks assessment of antibiotics in soils demonstrated that erythromycin(ERY), sulfamethoxazole(SMX), and doxycycline(DOX) may introduce high risks to soil ecosystem health, and more attention should be paid to the areas with intensive human activities that had potential high risk to soil ecosystem health. This study suggests that scientific land and soil management should be considered to prevent soil antibiotic pollution and sustain soil security in urban agglomeration. | Min Li Lei Yang Haw Yen Fangkai Zhao Xinmiao Wang Tianhui Zhou Qingyu Feng Liding Chen | 2023 | Journal of Environmental Sciences2023，，3： | 5 |
| 10 | Effects of Comprehensive Eccentricity of Involute Cam on Gear Profile Deviations显示文摘The manufacturing accuracy of ultra-precision master gears signifies the technological capability of the ultra-precision gear.Currently,there is little report about the manufacturing technologies of ultra-precision master gears at home and aboard.In order to meet the requirement of grinding ultra precision master gear,the gear grinder with flat-faced wheel Y7125 is chosen as the object machine tool and the geometric model of its precision generating part,the involute cam,is established.According to the structure of the involute cam,the effective working section and its adjustable range of the cam are determined,and the mathematical expressions of the effects of comprehensive eccentricity of the involute cam on gear profile deviations are derived.According to the primary harmonic trends of the deviation curve,it is shown that gear profile form and slope deviations in different work generating sections of the involute cam are different which the latter changes with the cam eccentricity obviously.Then,the issues of extreme values and methods of error compensation are studied and the conclusion that large adjustable range is benefit to search the optimal involute-cam section which is responding to the minimum gear profile deviations is obtained.A group of examples are calculated by choosing master gears with d=120 mm and m=2-6 mm and an involute cam with base diameter djcam =117 mm.And it is found that the maximum gear profile deviation counts for no more than 5% of the cam eccentricity after error compensation.A gear-grinding experiment on the master gear with m=2 mm is conducted by choosing different sections of the involute cam and the differences of gear profile deviations then the existence of the cam eccentricity are verified.The research discloses the rule of gear profile deviations caused by the comprehensive eccentricity of the involute cam and provides the theoretical guidance and the processing methods for grinding profile of the ultra precision master gear. | WANG Liding LING Siying MAYong WANG Xiaodong LOU Zhifeng | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 5 |

| 13 | Recent high-resolution glaciochemical record from a Dasuopu firn core of middle Himalayas显示文摘A 16.8 m firn core of middle Himalayas was recovered on the col of Dasuopu glacier in August 2006,being 7000 m above sea level.A total of 317 samples were measured for stable oxygen isotope ratios(δ18O)and major ion concentrations(Na+,NH4+,K+,Mg2+,Ca2+,Cl?,SO42?,and NO3?).The firn core dating and seasonal partitioning were carried out based on the marked seasonal variations along the stable oxygen isotopes and crustal species(Ca2+,Mg2+)profiles.The multi-parameters and high-resolution glaciochemical data set of Dasuopu firn core recorded the detailed chemical characteristics of pre-cipitation in high-elevation region,middle Himalayas,since 1991 A.D.,which mainly originated from the crustal and anthropogenic sources,while the sea-salt contribution was minor.The seasonal variability of major ion concentrations was dominated by the seasonal alternation of the prevalent air mass,at-mospheric circulation situation and precipitation regime.Linear regression analysis indicated that most of the variance in annual ionic fluxes can be explained by a linear dependence on snow accumu-lation rate. | WANG PengLing YAO TanDong TIAN LiDe WU GuangJian LI Zhen YANG Wei | 2008 | Chinese Science Bulletin2008，53，3： | 4 |

| 15 | Deep-blue organic light-emitting diodes based on a doublet d-f transition cerium(Ⅲ) complex with 100% exciton utilization efficiency显示文摘Compared to red and green organic light-emitting diodes(OLEDs),blue OLEDs are still the bottleneck due to the lack of efficient emitters with simultaneous high exciton utilization efficiency(EUE)and short excited-state lifetime.Different from the fluorescence,phosphorescence,thermally activated delayed fluorescence(TADF),and organic radical materials traditionally used in OLEDs,we demonstrate herein a new type of emitter,cerium(Ⅲ)complex Ce-1 with spin-allowed and parity-allowed d-f transition of the centre Ce^(3+) ion.The compound exhibits a high EUE up to 100% in OLEDs and a short excited-state lifetime of 42 ns,which is considerably faster than that achieved in efficient phosphorescence and TADF emitters.The optimized OLEDs show an average maximum external quantum efficiency(EQE)of 12.4% and Commission Internationale de L’Eclairage(CIE)coordinates of(0.146,0.078). | Liding Wang Zifeng Zhao Ge Zhan Huayi Fang Hannan Yang Tianyu Huang Yuewei Zhang Nan Jiang Lian Duan Zhiwei Liu Zuqiang Bian Zhenghong Lu Chunhui Huang | 2020 | Light(Science & Applications)2020，9，1： | 3 |
| 16 | The effects of land use on runoff and soil nutrient losses in a gully catchment of the hilly areas:implications for erosion control显示文摘Serious soilerosion is one ofthe majorissues threatening sustainable land use in semiarid areas,especially in the LoessPlateau ofChina.Understanding the effectsofland use on soiland water loss is important for sustainable land use strategy. Two sub-catchments: catchment A (CA) and catchment B (CB) with distinct land uses were selected to measure soil moisture,runoff and soil nutrientlossin Da Nangou catchmentofthe LoessPlateau ofChina.The effectsofland use patterns on runoffand nutrientlosseswere analyzed based on soilmoisture pattern by kriging and soilnutrients using multiple regression model.The resultsindicated thatthere were significantdifferencesin runoff yield and soil nutrient losses between the two sub-catchments. W ith similar land uses, the CA produced an average sediment yield of 49 kg ha-1 and 22.27 kg ha-1 during two storm events. M eanwhile,there was almostno runoffin the CB with dissimilarland uses during the same events. Bufferzonesshould be established to re-absorb runoffand to trap sedimentsin catchmentwith similar land use structure such as the CA.M oreover,land use managementstrategy aiming to increase the infiltration threshold ofhydrologicalresponse unitscould decrease the frequency ofrunoffoccurrence on aslopeand catchmentscale. | WANG Jun FU Bojie QIU Yang CHEN Liding CHEN Chen HU Baodong | 2005 | Journal of Geographical Sciences2005，15，4： | 3 |
| 17 | Efficient rare earth cerium(Ⅲ)complex with nanosecond d-f emission for blue organic light-emitting diodes显示文摘In the field of RGB diodes,development of a blue organic light-emitting diode(OLED)is a challenge because of the lack of an emitter which simultaneously has a short excited state lifetime and a high theoretical external quantum efficiency(EQE).We demonstrate herein a blue emissive rare earth cerium(III)complex Ce-2 showing a high photoluminescence quantum yield of 95%and a short excited state lifetime of 52.0 ns in doped film,which is considerably faster than that achieved in typical efficient phosphorescence or thermally activated delayed fluorescence emitters(typical lifetimes>1μs).The corresponding OLED shows a maximum EQE up to 20.8%and a still high EQE of 18.2%at 1000 cd m^(-2),as well as an operation lifetime 70 times longer than that of a classic phosphorescence OLED.The excellent performance indicates that cerium(III)complex could be a candidate for efficient and stable blue OLEDs because of its spin-and parity-allowed d-f transition from the Ce^(3+)ion. | Zifeng Zhao Liding Wang Ge Zhan Zhiwei Liu Zuqiang Bian Chunhui Huang | 2021 | National Science Review2021，8，2： | 3 |

| 19 | Ecological Environment Conservation and Restoration and Sustainable Development of Minqin Oasis显示文摘Minqin oasis in the lower reaches of the Shiyang River is a main natural barrier for the Wuwei Basin. Due to the combined influence of human activities and natural factors in the past half a century, water quality in the lower reaches of the Shiyang River decreased and ecological environment deteriorated, which influenced sustainable development of this area and surrounding area seriously. This paper analyzed current situation and reasons of the deteriorated ecological environment in the lower reaches of the Shiyang River, and proposed that water environment regulation was the primary task in the eco-environment control of Minqin area, specifically,(a) By using existing policies, accelerating the construction of water-saving agriculture in the middle reaches of the Shiyang River, water quantity in the lower reaches would be guanranted, water shortage for agricultural production and ecological use in Minqin oasis would be relieved;(b) Unreasonable human activities such as overexploitation of underground water should be controlled strictly;(c) Water conservancy project should be developed vigorously to ensure rate of flow. It was expected that the above schemes would contribute to the benign circulation of ecological environment in Minqin oasis. | WANG Lide YAO Tuo XU Feng HAN Fugui GUO Chunxiu WANG Fangling Li Faming | 2016 | Journal of Landscape Research2016，8，1： | 2 |
| 20 | Seasonal transition characteristics of the westerly jet: Study based on field observations at an altitude of 6900 m on the Mt. Xixiabangma Dasuopu glacier显示文摘To better understand ultra-high-altitude climate characteristics and their changes, an automatic weather station was installed on August 4, 2005 on the Mt. Xixiabangma Dasuopu glacier (28°23.04′N, 85°43.72′E, 6900 m a.s.l.) in the middle of the Himalayas. Mountain weather conditions were observed continuously and automatically. This paper is the first to publish meteorological data for a whole year for a high-elevation region, and analyze wind direction, wind speed, air temperature, air pressure and humidity. Analysis of the observation data reveals that this region was strongly influenced by the westerly jet from October 10, 2005 to April 21, 2006 and by the Indian monsoon from May to September. The seasonal transitions of the westerly jet were characterized by changes in meteorological elements. In winter, influenced by the westerly jet, the wind speed in the study region was very high and fluctuated violently, gale days were frequent, temperature and air pressure fluctuated dramatically, the diurnal range of temperature decreased and the diurnal range of air pressure increased, relative humidity and specific humidity declined sharply, and air was dry. In summer, influenced by the Indian monsoon, the relative humidity and specific humidity were high. In addition, we analyzed reanalysis data for the location of the automatic weather station. The results confirmed that this region was strongly affected by the westerly jet from October 10, 2005 to April 21, 2006 and the observations that the seasonal transitions of the westerly jet were characterized by changes in meteorological elements. | LI ShengHai YAO TanDong TIAN LiDe WANG PengLing | 2011 | Chinese Science Bulletin2011，56，18： | 2 |
