| 1 | Characteristics of paleoflood deposits archived in unit T0403 of Yuxi Site in the Three Gorges reservoir areas,China显示文摘Based on the detailed analyses,multi-proxies such as AMS 14 C dating,grain size,component and morphology of heavy minerals,micromorphology of zircon,magnetic susceptibility,Rb/Sr and Hg content are used to research the paleoflood sediments archived in the Yuxi Site.The research indicates that, since 7.6 kaBP,at least 16 times of paleoflood with water level above Wusong Elevation 147.024 m(a.s.l.) left deposits in the Neolithic layers of unit T0403 from the Yuxi Site.The results are induced from the following aspects:(1)The plaeoflood sediments take on great similarities with modern flood sediments in the Yuxi Site and Zhongba Site in probability cumulative curves which mainly show a pattern of 3 segments in fluvial pattern.(2)There is some resemblance between the heavy mineral components and the zircon shape characteristics of paleoflood deposits and those of modern flood deposits.(3) Magnetic susceptibility values(40.44―70.10SI)are lower than those of sediments from cultural layers (59.59―188.68SI).(4)Hg values(290.71―742.51 ng/g)are lower than those of sediments from cultural layers(344.16―10518.17 ng/g).(5)Rb/Sr values are higher than those of sediments from cultural layers, while those of the 4th,5th,6th,7th,8th cultural layers are high,which shows that they are inundated by paleoflood.The reason for many flood deposits existing is related to the site situated on the first terrace where the Yuxi River joins with the Yangtze River.As there are some similarities between the plaeoflood sediments and those of the Zhongba Site,it is feasible to confirm the existence of paleoflood sediments based on the above points. | ZHU Cheng MA ChunMei XU WeiFeng BAI JiuJiang ZHENG ChaoGui ZHU GuangYao WANG HuiLin CHEN Ye LU XueFeng | 2008 | Chinese Science Bulletin2008，53，S1： | 16 |
| 2 | Numerical Simulation of the Regional Ocean Circulation in the Coastal Areas of China显示文摘The regional ocean circulation in the coastal areas of China (including a part of the western PacificOcean, the South China Sea and the Bay of Bengal et al.) is simulated by using the improved Princeton University ocean circulation model (POM). Compared with the modeling results obtained by the large-scaleocean general circulation model (OGCM), the basic ocean circulation features simulated by the regionalocean circulation model al-e in good agreement with that simulated by OGCM and some detailed characteristics such as the regional ocean circulation, sea temperature, salinity and flee sea surface height have alsobeen obtained which are in good accord with the observations. These results indicate that the regional oceancirculation model has good capability to produce the legional ocean circulation characteristics and it can beused to develop coupled legional ocean-atmospheric model systems. | 张耀存 钱永甫 | 1999 | Advances in Atmospheric Sciences1999，16，3： | 12 |
| 3 | Gastrointestinal manifestations of Henoch-Schonlein purpura: A report of two cases显示文摘Henoch-Schonlein purpura(HSP) is a small vessel vasculitis mediated by type Ⅲ hypersensitivity with deposition of Ig A immune complex in the walls of vessels. It is a multi-system disorder characterizedby palpable purpura, arthritis, glomerulonephritis and gastrointestinal manifestations and commonly occurs in children and young adults. The patients with gastrointestinal involvement usually present with colicky abdominal pain, vomiting and melena. The imaging findings include multifocal bowel thickening with mucosal hyperenhancement, presence of skip areas, mesenteric vascular engorgement, with involvement of unusual sites like stomach, duodenum and rectum. These imaging findings in a child or young adult with appropriate clinical findings could suggest HSP. | Parameswaran Prathiba Rajalakshmi Kalyanasundaram Srinivasan | 2015 | World Journal of Radiology2015，7，3： | 12 |
| 4 | Dynamic changes in lakes in the Hoh Xil region before and after the 2011 outburst of Zonag Lake显示文摘Zonag, Kusai, Hedin Noel and Yanhu Lakes are independent inland lakes in the Hoh Xil region on the Qinghai-Tibet Plateau. In September2011, Zonag Lake burst after the water level had increased for many years. Floods flowed through Kusai and Hedin Noel Lakes into Yanhu Lake; since then, the four small endorheic catchments merged into one larger catchment. This hydrological process caused the rapid shrinkage of Zonag Lake and continuous expansion of Yanhu Lake. In this study,based on satellite images, meteorological data and field investigations, we examined the dynamic changes in the four lakes and analyzed the influencing factors. The results showed that before 2011, the trends in the four lake areas were similar and displayed several stages. The change in the area of Zonag Lake corresponded well to the change in annual precipitation(AP), but the magnitude of the change was less than that of a non-glacier-fed lake. Although increased precipitation was the dominant factor that caused Zonag Lake to expand, increased glacier melting and permafrost thawing due to climate warming also had significant effects. After the 2011 outburst of Zonag Lake, due to the increasing AP and accelerating glacier melting, the increases in water volume of the three lakes were absorbed by Yanhu Lake, and Yanhu Lake expanded considerably. According to the rapid growth rates in water level and lake area, Yanhu Lake is likely to burst in 1-2 years. | LIU Wen-hui XIE Chang-wei ZHAO Lin WU Tong-hua WANG Wu ZHANG Yu-xin YANG Gui-qian ZHU Xiao-fan YUE Guang-yang | 2019 | Journal of Mountain Science2019，16，5： | 11 |
| 5 | Sequence-stratigraphic frameworks and their palaeogeographic patterns for the Permian Lopingian of the Dianqiangui Basin and its adjacent areas of Southwestern China显示文摘The Permian Lopingian in the Dianqiangui Basin and its adjacent areas is marked by the coal measures of the Wuchiapingian and the carbonate strata of the Changhsingian stages. For the Lopingian of the Dianqiangui Basin and its adjacent areas,the diversity of sedimentary facies and the obviousness of facies change provide an advantaged condition on a study of sequence stratigraphy. Approximately,the Wuchiapingian stage constitutes a third-order sequence and the Changhsingian stage forms an-other. For the Wuchiapingian stage in the study area,coal-measures were developed on the attached platform and,in addition,a special coal-measure that is composed of both limestone beds and coal beds was also developed in the central part of some isolated platforms. Grain-bank grainstones and packstones were formed on the margin of the attached platform as well as in the windward part of iso-lated platforms. For the Changhsingian stage in the study area,open-platform limestones were formed on the attached platform,while sponge-reef limestones were developed both on the margin of the at-tached platform and on the isolated platforms. The Lopingian Series is a set of basin-facies muddy shales with interbeds of silicalites in the inter-platform basin,which appears a set of the large-thick coarse clastic strata of molasses covering direct the deep-water strata from the Devonian to the Per-mian Yangsingian in the Qinzhou-Fangcheng region in the southern part of the study area. All of these features indicate the complexity of temporal-spatial facies-changes. Sequence-stratigraphic frame-works could be established,which would illustrate two types of facies-changing surfaces and dia-chronisms in the stratigraphic records,based on the combination of both biostratigraphic and chronostratigraphic materials and the regularity reflected by temporal evolutionary succession of sediments as well as spatial distributional patterns of sedimentary facies. Ultimately,features of sedi-mentary succession and palaeogeographical evolution of the Permian Lopingian in the study area are revealed clearly in a series of the panel diagrams of sequence-stratigraphic frameworks and the outline maps showing the sedimentary-facies and palaeogeography. The Permian Lopingian formed by two third-order sequences differs from the stratigraphy of the same era characterized by the constant re-gression along Euramerica. Most specially,if the end-Guadalupian mass-extinction event is genetically related to a regressive event represented by the unconformity of the first episode of the Dongwumovement in the study area,the mass-extinction event at the turn from the Permian to the Triassic is genetically related to a rapid transgressive event re-flected by the drowning unconformity in the study area. These phenomena might reveal a complex rela-tionship between mass-extinction events and trans-gressive-regressive events. | MEI MingXiang MA YongSheng DENG Jun CHU HanMin ZHENG KuanBing | 2007 | Science China Earth Sciences2007，50，6： | 8 |
| 6 | A COMPUTER MODEL FOR CALCULATING THE DURATION OF SUNSHINE IN MOUNTAINOUS AREAS显示文摘Considering the fact that the sunrise (or sunset) at any point of the mountain is generally not earlier (or later) than that at the horizontal one, the Potential Duration of Sunshine (PDS) at horizontal spot T0 could be divided into n+1 periods, the lengths of the former n periods are all equal to the time interval △T. So n is calculated | 李占清 翁笃鸣 | 1988 | Chinese Science Bulletin1988，33，19： | 8 |
| 7 | Deep electrical structure of the Sulu orogen and neighboring areas显示文摘Because of the discovery of ultrahigh pressure metamorphic (UHPM) belt beneath the Sulu (Jiangsu Province-Shandong Province) orogen, this area has become a focused subject of current geoscience, as it has a close relationship with the evolution of the orogen and the neighboring North China craton. Probing the deep structure beneath this area would be of great significance for the geological inter- pretation of this issue. In this study, we make an analysis of magnetotelluric (MT) data along a profile across the Sulu orogen to provide evidence of deep structure below this region. The profile begins in west from the North China block, extending in S129oE, across the Tan-Lu fault, Sulu UHPM zone, and Sulu high pressure metamorphic (HPM) zone, and terminates in the Yangtze block in east. We use the nonlinear conjugate gradient method and TE-TM combined mode to perform inversion and interpreta- tion of the MT data, and obtain an electrical structure image above depth of 150 km along the profile. It shows that the structure can be divided into seven sections in lateral direction, between which the electric boundaries coincide well with the major faults, such as the Tan-Lu, Haizhou-Siyang, and Ji- ashan-Xiangshui faults. In vertical direction the electrical structure can be subdivided into six layers of different resistivities. It is noted that there exist high-conductivity areas in crust below the North China block and Yangtze block, while such a feature is not present beneath the Sulu orogen, which is very different from the Dabie orogen. It is also observed that a fairly continuous zone of relatively low-resistivity exists at depths of 50-90 km of the electrical structure image, which is presumably a weak zone in the uppermost mantle. Just below this low-resistivity zone are the relatively high- resis- tivity layer of the North China block, relatively low-resistivity layer of the Sulu orogen, and relatively high-resistivity layer of the Yangtze block, all in the shallow upper mantle, respectively. From the whole 2D electrical structure image, there is no abnormally low-resistivity layer in the shallow upper mantle beneath the Sulu orogen and neighboring areas, indicating that no hot asthenoshperic material asso- ciated with lithospheric thinning exists at present. | XIAO QiBin ZHAO GuoZe WANG JiJun ZHAN Yan CHEN XiaoBin TANG Ji CAI JunTao WAN ZhanSheng WANG LiFeng MA Wei ZHANG JiHong | 2009 | Science China Earth Sciences2009，52，3： | 7 |
| 8 | Do farmers care about climate change? Evidence from five major grain producing areas of China显示文摘Using a logistic model,this paper empirically investigated farmers’perception of climate change and its determinants based on a field survey of 1 350 rural households across five major grain producing provinces in China.The results show:i)There is an apparent difference in perception levels for long-term temperature and precipitation changes.Specifically,57.4%of farmers perceived the long-term temperature change correctly,but only 29.7%of farmers perceived the long-term precipitation change correctly;ii)The factors influencing the farmers’perceptions are almost completely different between precipitation and temperature,the former are mostly agriculture related,while latter are mostly non-agriculture related,except for farm size;and iii)Farmers are not expected to pay more attention to long-term precipitation changes over the crop growing seasons,because less than 30%of farmers can correctly perceive long-term precipitation change.Therefore,to improve the accuracy of farmers’perceptions of climate change,the government is recommended to:i)enhance education and training programs;ii)speed up land transfer and expand household land farm size;iii)develop farmer cooperative organizations;iv)invest more in agricultural infrastructure,specifically in major grain producing regions;and v)improve the agricultural environment and increase farming income. | SONG Chun-xiao LIU Rui-feng Les Oxley MA Heng-yun | 2019 | Journal of Integrative Agriculture2019，18，6： | 6 |
| 9 | Object oriented land cover classification using ALS and GeoEye imagery over mining area显示文摘An object oriented coal mining land cover classification method based on semantically meaningful image segmentation and image combination of GeoEye imagery and airborne laser scanning (ALS) data was presented. First, DEM, DSM and nDSM (normalized Digital Surface Model, nDSM) were extracted from ALS data. The GeoEye imagery and DSM data were combined to create segmented objects based on neighbor regions merge method. Then 10 kinds of objects were extracted. Different kinds of vegetation objects, including crop, grass, shrub and tree, can be extracted by using NDVI and height value of nDSM. Water and coal pile field was extracted by using NDWI and the standard deviation of DSM method. Height differences also can be used to distinguish buildings from road and vacant land, and accurate building contour information can be extracted by using relationship of neighbor objects and morphological method. The test result shows that the total classification accuracy of the presented method is 90.78% and the kappa coefficient is 0.891 4. | YU Hai-yang, CHENG Gang, GE Xiao-san, LU Xiao-ping Key Laboratory of Mine Spatial Information Technologies of State Bureau of Surveying and Mapping, Henan Polytechnic University, Jiaozuo 454000, China | 2011 | 中国有色金属学会会刊:英文版2011，21，S3： | 6 |
| 10 | ECOLOGICAL AND SOCIO-ECONOMIC REHABILITATION IN THE KARST OF SOUTHWEST CHINA显示文摘The Karst of Southwest China is a typical representative of poverty stricken region with impoverishment-degradation spiral. To essentially break away from this vicious circle, the local ecology, economy and society should be rehabilitated, and hence to strengthen the self-development capacity building of the localities. Two considerations are stressed in this article: (1) Poverty alleviation is a system project with great complexities. Any single approach is difficult to success and integrated measures should be taken. (2) Some typical and feasible areas should be selected to demonstrate the project of poverty alleviation and ecological, socio-economic reconstruction. Then, they can be used as a model to promote the sustainable development of the whole region. Based upon these ideals, a project entitled “Reversal of Impoverishment-Degradation Spiral in the Karst of Southwest China' was proposed and has been listed in 《Priority Programme for China’s Agenda 21》. | Cai Yunlong Department of Geography, Peking University, Beijing 100871 People’s Republic of China | 1997 | Journal of Geographical Sciences1997，7，2： | 5 |
| 11 | Delineation of Potential Mineral Resources RegionBased on Geo-anomaly Unit显示文摘The geological anomaly unit method (GAUM) is a new way to delineate and evaluate ore finding targets in line with the “geological anomaly ore finding theory”. Comprehensive ore finding information from geological, geochemical and geophysical data is used for quantitative measurement of the “ore forming geological anomaly unit” in this paper. The main procedures are shown as follows: (1) The geo anomalous events associated with gold mineralization are analyzed in Tongshi gold field; (2) The zonation in the concentrated heavy minerals and the stream sediment elements of ore forming geo anomaly are studied in detail; (3) The deep geological structural framework is deduced by means of the synthetic geological interpretation of gravity and magnetic information; (4) The ore controlling geo anomalies and ore anomalies are chosen as the variables of the favorable ore forming indexes that can be used for the quantitative delineation and evaluation of the potential ore forming regions. | Chen Yongqing Faculty of Earth Resources, China University of Geosciences, Wuhan 430074 The Center for Development and Research, China Geological Survey, Beijing 100083 Liu Hongguang Faculty of Earth Resources, China University of Geosciences, Wuhan 4 | 2000 | Journal of Earth Science2000，19，2： | 5 |
| 12 | Industrial Poverty Alleviation Model in Southwestern High-altitude Mountainous Areas of China——A Case Study of Industrial Poverty Alleviation of Xueshan Township in Luquan County of Yunnan Province through Planting Codonopsis pilosula显示文摘Due to the severe restrictions of natural conditions and ecological environment,high-altitude mountainous areas usually become the ' hard bones' in the battle against poverty. Xueshan Township,Luquan Yi and Miao Autonomous County of Yunnan Province,located in the alpine valley of Jinsha River,is a major township with wide and deep poverty,and the incidence of poverty is up to 45. 00%. In recent years,Xueshan Township has insisted on the battle against poverty,made effort to develop the Codonopsis pilosula industry,and successfully developed a road to poverty alleviation through C. pilosula industry,and formed a unique industrial poverty alleviation model by the end of 2018,the incidence of poverty dropped to 0. 74%. Based on field survey and interview,this paper analyzes and summarizes the specific practices,main results,practical experience and promotion and application measures of the poverty alleviation model of C. pilosula planting industry in Xueshan Township,in the hope of providing certain reference for the targeted poverty alleviation in similar areas in Yunnan Province and other provinces of China. | Zisheng YANG Renyi YANG Yanbo HE Chonghui LU En ZHU Yaohan PI Mingxin WU Ying XIONG | 2019 | Asian Agricultural Research2019，11，3： | 4 |
| 13 | Distribution of glycerol ethers in Turpan soils:implications for use of GDGT-based proxies in hot and dry regions显示文摘Proxies based on glycerol dialkyl glycerol tetraethers (GDGTs),a suite of membrane lipids occurring ubiquitously in soils,have generated increasing interest in quantitative paleo-environmental reconstruction.Hot and dry climates are likely to have occurred in the geological past;however,the limitations and applicability of these proxies to hot and dry environments are still unknown.In this study,we analyzed the GDGT distribution in the Turpan (TRP)basin of China,where the highest soil temperature can be approximately 70℃,and the mean annual precipitation (MAP)is 15.3 mm.We compared GDGT-based proxies among TRP soils,Nanyang (NY) soils,and Kunming (KM)soils;these three sites exhibit similar mean annual air temperature (MAAT)albeit contrasting temperature seasonality and MAP.Archaeal isoprenoidal GDGTs (isoGDGTs)dominate over bacterial branched GDGTs (brGDGTs)in most TRP soils;this is a characteristic GDGT distribution pattern for soils from dry regions globally.Another feature is the anomalously high GDGT-0/crenarchaeol ratio,which is generally attributed to the contribution of anaerobic methanogenic archaea by previous studies;however,these anaerobic archaea are unlikely to be highly abundant in the dry TRP soils, indicating that certain uncultured halophilic Euryarchaeota are likely to produce a significant amount of GDGT-0that finally results in a high GDGT-0/Cren ratio.The changes in the salinity of the TRP soils appear to be an important factor affecting the MBT'5ME and the relative abundance of 6-vs.5-methyl pentamethylated brGDGTs (IRIIa,).This is likely to introduce certain scatters in the correlations between MBT'5ME and MAAT and that between IRIIa,and pH determined at the global scale.A comparison of the MBT'5ME-inferred temperature between TRP,NY,and KM soils does not indicate a significant bias toward summer temperature,indicating that brGDGT paleo- thermometers in soils could reflect the MAAT. | Jingjie ZANG Yanyan LEI Huan YANG | 2018 | Frontiers of Earth Science2018，12，4： | 4 |
| 14 | Effects of Guideline-based Hypertension Management in Rural Areas of Guangdong Province显示文摘Background: Despite the improvement in the health care industry, the rates of undetected, untreated, and uncontrolled hypertension (HTN) are still very high, especially in rural areas of China. The aim of this study was to investigate the efficacy and efficiency of a guideline-based HTN management (novel therapy) in population of rural areas of Guangdong Province. Methods: Totally, 3113 patients with essential HTN in a rural area of Guangdong Province were enrolled and assigned to two groups, named traditional (n = 372) and novel therapeutic (n = 2741 ) groups, respectively. Patients in the traditional group were treated routinely, and patients in the novel group were treated in a novel model characterized by regular educational programs for hypertensive populations, close monitoring of blood pressure in combination with finely tuned antihypertensive medications, strict implementation of lifestyle modification and improving medical knowledge and skill of local medical staff efficiently. After 2 years of follow-up, primary endpoints including magnitude of systolic and diastolic blood pressures (SBP and DBP) decrease, treated and controlled rates, as well as secondary endpoints, were evaluated in both groups. Results: Initially, the treated rate was significantly higher in traditional group than that of novel group (71.15% vs. 64.99%, P 〈 0.05), while the controlled rates were comparable and insignificant difference between baseline BP in both groups (31.07% vs. 26.88%, P 〉 0.05). Four variables were significantly different, namely smoking rate, daily vegetable consumption (VC), and serum levels of low-density lipoprotein-cholesterol and fasting blood glucose between these two groups. After 2 years of follow-up, decreases in SBP and DBP were more prominent in the novel group (P 〈 0.001). Treated and controlled rates in both groups were both increased. Nevertheless, in comparison to the traditional group, controlled rate increased more significantly in the novel group (64.31% vs. 37.85%, P 〈 0.001). Variables indicating lifestyle modification such as high sodium consumption, percentages of alcohol abuse, daily VC were profoundly improved in the novel group. Conclusions: The guideline-based HTN management implemented in the current study was beneficial for HTN control in rural areas of Guangdong Province. | Guang Li An-Ping Cai Yu-Jin Mo Ji-Yan Chen Rui-Bing Wei Yu-Qing Huang Song-Tao Tang Ying-Ling Zhou Ying-Qing Feng | 2015 | Chinese Medical Journal2015，，6： | 4 |

| 17 | The mechanism of farmland marginalization in Chinese mountainous areas:Evidence from cost and return changes显示文摘Farmland marginalization has become the main trend of Iand-use change in the mountainous areas of China.Using annual survey data of major agricultural production costs and earnings at national and provincial levels in China,this study aims to analyze the reasons and mechanism behind farmland marginalization in mountainous areas.We find that farmers on plains are able to reduce their per mu labor input effectively through in tensive use of agricultural machinery,which has minimized the impact of the increase in labor price.However,it is extremely challenging for farmers in mountainous areas to use the same method owing to the rough terrain.Thus,per laborer farming area in these areas has increased relatively slowly,causing a widening gap in agricultural labor productivity between the two regions.With the rapid rise in labor costs since 2003,the marginalization of cultivated land in mountainous areas is evident.In 2013,the net profit of agricultural production in mountainous China fell below zero.Since 2000,the Iand-use and land?cover change in these areas was characterized by the reduction of farmland area,reforestation,and the enhancement of the NDVI value.The high correlation between the NDVI change rate and the ratio of change in farmland(r=-0.70)and forest(r=0.91)in mountainous areas at provincial level further attests to the trend of farmla nd margi nalization there.Fin ally,we summarize the mecha nism of such marginalization against the backdrop of the rapid increase in the opport unity cost of farming and the rapid fall of agricultural labor forces in mountainous areas.This study contributes to a deep understanding of the development process of farmland marginalization and abandonment as well as forest transition in Chinese mountainous areas. | LI Shengfa LI Xiubin | 2019 | Journal of Geographical Sciences2019，29，4： | 4 |

| 19 | STUDY ON THE SPATIAL DEVELOPMENT OF RURAL AREAS IN CHINA显示文摘This paper makes a comprehensive analysis of the new trends in the economic activities in the Chinese rural areas in terms of the spatial process, spatial behaviour, spatial relations, spatial structure and spatial disparitics. It also discusses the various 'rural diseases' induced by the decentralization and incoordination of the spatial development in these areas. In the writer's opinion, the study on the spatial development of Chinese rural areas should concentrate on the renewal of the existing theory and practice. Using the spatial economic system theory to replace the traditional agricultural location theory, allocation theory, areal differentiating theory and the community theory, the author has put forward Chinese rural spatial economics which can function as the basis and guidance for the study on spatial development of rural areas in China. | 曾菊新 | 1995 | Chinese Geographical Science1995，5，1： | 3 |
| 20 | A Stackelberg game approach for demand response management of multi-microgrids with overlapping sales areas显示文摘Microgrids are increasingly participating directly in the electricity market as sellers in order to fulfill the power demand in specific regions.In this study,we consider a demand response management model for multi-microgrids and multi-users,with overlapping sales areas.We construct a Stackelberg game model of microgrids and users,and then analyze the equilibrium strategies systematically.As such,we prove that there is a unique Stackelberg equilibrium solution for the game.In equilibrium,the electricity price strategies of the microgrids and the demand strategies of the users achieve a balance.Furthermore,we propose a numerical algorithm,supported by a simulation,to compute the equilibrium solution and give the proof of convergence. | Jun LI Guangqing MA Tao LI Wushun CHEN Yu GU | 2019 | Science China(Information Sciences)2019，62，11： | 3 |
