| 1 | The land use and land cover change database and its relative studies in China显示文摘In the mid-1990s, we established the national operative dynamic information serving systems on natural resources and environment. During building the land-use/land-cover change (LUCC)database for the mid-1990s, 520 scenes of remotely sensed images of Landsat Thematic Mapper (TM) were interpreted into land-use/land-cover categories at scale of 1:100,000 under overall digital software environment after being geo-referenced and ortho-rectified. The vector map of land-use/land-cover in China at the scale of 1:100,000 was recently converted into a 1-km raster database that captures all ofthe high-resolution land-use information by calculating area percentage for each kind of land use category within every cell. Being designed as an operative dynamic information serving system,monitoring the change in land-use/land-cover at national level was executed. We have completed the updating of LUCC database by comparing the TM data in the mid-1990s with new data sources received during 1999-2000 and 1989-1990. The LUCC database has supported greatly the national LUCC research program in China and some relative studies are incompletely reviewed in this paper. | LIU Jiyuan, LIU Mingliang, DENG Xiangzheng, ZhuangDafang,ZHANG Zengxiang, LUO Di(1.

| 4 | Spatial patterns and driving forces of land use change in China during the early 21st century显示文摘Land use and land cover change as the core of coupled human-environment systems has become a potential field of land change science (LCS) in the study of global environmental change. Based on remotely sensed data of land use change with a spatial resolution of 1 km × 1 km on national scale among every 5 years, this paper designed a new dynamic regionalization according to the comprehensive characteristics of land use change including regional differentiation, physical, economic, and macro-policy factors as well. Spatial pattern of land use change and its driving forces were investigated in China in the early 21st century. To sum up, land use change pattern of this period was characterized by rapid changes in the whole country. Over the agricultural zones, e.g., Huang-Huai-Hai Plain, the southeast coastal areas and Sichuan Basin, a great proportion of fine arable land were engrossed owing to considerable expansion of the built-up and residential areas, resulting in decrease of paddy land area in southern China. The development of oasis agriculture in Northwest China and the reclamation in Northeast China led to a slight increase in arable land area in northern China. Due to the 'Grain for Green' policy, forest area was significantly increased in the middle and western developing regions, where the vegetation coverage was substantially enlarged, likewise. This paper argued the main driving forces as the implementation of the strategy on land use and regional development, such as policies of 'Western Development', 'Revitalization of Northeast', coupled with rapidly economic development during this period. | LIU Jiyuan ZHANG Zengxiang XU Xinliang KUANG Wenhui ZHOU Wancun ZHANG Shuwen LI Rendong YAN Changzhen YU Dongsheng WU Shixin JIANG Nan | 2010 | Journal of Geographical Sciences2010,20,4: | 154 |

| 11 | Distribution of available soil water capacity in China显示文摘The available soil water capacity (ASWC) is important for studying crop production, agro-ecological zoning, irrigation planning, and land cover changes. Laboratory determined data of ASWC are often not available for most of soil profiles and the nationwide ASWC largely remains lacking in relevant soil data in China. This work was to estimate ASWC based on physical and chemical properties and analyze the spatial distribution of ASWC in China. The pedo-transfer functions (PTFs), derived from 220 survey data of ASWC, and the empirical data of ASWC based on soil texture were applied to quantify the ASWC. GIS technology was used to develop a spatial file of ASWC in China and the spatial distribution of ASWC was also analyzed. The results showed the value of ASWC ranges from 15×10^-2 cm^3·cm^-3 to 22×10^-2 cm^3·cm^-3 for most soil types, and few soil types are lower than 15×10^-2 cm^3·cm^-3 or higher than 22×10^-2 cm^3·cm^-3, The ASWC is different according to the complex soil types and their distribution, It is higher in the east than that in the west, and the values reduce from south to north except the northeastern part of China. The “high” values of ASWC appear in southeast, northeastern mountain regions and Northeast China Plain. The relatively “high” values of ASWC appear in Sichuan basin, Huang-Huai-Hai plain and the east of Inner Mongolia. The relatively “low” values are distributed in the west and the Loess Plateau of China. The “very low” value regions are the northern Tibetan Plateau and the desertified areas in northern China. In some regions, the ASWC changes according to the complex topography and different types of soils. Though there remains precision limitation, the spatial data of ASWC derived from this study are improved on current data files of soil water retention properties for Chinese soils. This study presents basic data and analysis methods for estimation and evaluation of ASWC in China. | ZHOUWenzuo LIUGaohuan PANJianjun FENGXianfeng | 2005 | Journal of Geographical Sciences2005,15,1: | 51 |

| 14 | Fuzzy Comprehensive Evaluation Model for Water Resources Carrying Capacity in Tarim River Basin,Xinjiang,China显示文摘This paper explores the method of comprehensive evaluation of water resources carrying capacity and sets up an evaluation model applying the fuzzy comprehensive evaluation method. Based on the data of nature,society,economics and water resources of the Tarim River Basin in 2002,we evaluated the water resources carrying capacity of the basin by means of the model. The results show that the comprehensive grades are 0.438 and 0.454 for Aksu and Kashi prefectures respectively,where the current water resources exploitation and utilization has reached a relative high degree and there is only a very limited water carrying capacity,0.620 for Kizilsu Kirgiz Autonomous Prefecture,where water resources carrying capacity is much higher,and in between for Hotan Prefecture and Bayingolin Mongo-lian Autonomous Prefecture. As a whole,the comprehensive grade of the Tarim River Basin is 0.508 and the current water resources exploitation and utilization has reached a relative high degree. Thus,we suggest that the integrated management of the water resources in the basin should be strengthened in order to utilize water resources scientifically and sustainably. | MENG Lihong CHEN Yaning LI Weihong ZHAO Ruifeng | 2009 | Chinese Geographical Science2009,19,1: | 55 |

| 16 | China's regional transport dominance: Density, proximity, and accessibility显示文摘Transport infrastructure plays an important role in shaping the configuration of spatial socio-economic structures and influences regional accessibility.This paper defines transport dominance from three aspects:quality,quantity,and advantage,measured by density,proximity,and accessibility indices.County is the basic unit for analysis.The results reveal:(1)Transport dominance statistically follows a partial normal distribution.A very few counties,1.4%of the total,have extremely high transport dominance which strongly supports the socio-economic development in these areas.In contrast,one eighth of all counties have poor transport dominance which impedes local socio-economic development to some extent. The remaining areas,about 70%of the counties,have median transport dominance.(2) Transport dominance is spatially unevenly distributed,with values decreasing gradually from the coastal area to the inland area.Areas in the first-highest level of transport dominance are mainly concentrated in the Yangtze River Delta,the Greater Beijing area,and the Pearl River Delta.Areas in the second-highest level are focused in Chengdu,Chongqing,and Wuhan metropolitan areas.Provincial capitals and a few other counties belong to the third-highest level. | JIN Fengjun WANG Chengjin LI Xiuwei WANG Jiao'e | 2010 | Journal of Geographical Sciences2010,20,2: | 58 |
| 17 | Potential Role of Feldspathic Sandstone as a Natural Water Retaining Agent in Mu Us Sandy Land,Northwest China显示文摘This paper analyzed the water-retention mechanism of feldspathic sandstone(fine-(<1 mm diam.)and gravel-sized(2-3 cm diam.)in Mu Us Sandy Land,Northwest China.The objective of this study is to study the effect of feldspathic sandstone amendment on water retention in sandy land.The results showed that as the proportion of fine feldspathic sandstone in the sandy land soil increased,the soil texture changed from sand to silt loam,the capillary porosity gradually increased from 26.3%to 44.9%,and the soil saturated hydraulic conductivity decreased from 7.10 mm/min to 0.07 mm/min.Feldspathic sandstone gravel formed micro-reservoirs in the sandy land soil,playing the role of a′water absorbent′and′water retaining agent′in sandy land.Amendment with feldspathic sandstone can increase water retention in the arable layer of sandy land by 67%.This study provides a theoretical basis for the amelioration of sandy land on a large scale.It can be concluded that amendment with feldspathic sandstone can improve the physical properties of sandy land soil and increase soil water retention. | HAN Jichang XIE Jiancang ZHANG Yang | 2012 | Chinese Geographical Science2012,22,5: | 52 |

| 19 | The response of lake-glacier variations to climate change in Nam Co Catchment, central Tibetan Plateau, during 1970-2000显示文摘Based upon the 1970 aero-photo topographic map,and TM/ETM satellite images taken in 1991 and 2000,the authors artificially interpreted boundaries of lake and glaciers in Nam Co Catchment,and quantified lake-glacier area variations in different stages by 'inte-grated method' with the support of GIS. Results show that from 1970 to 2000,lake area in-creased from 1942.34 km2 to 1979.79 km2 at a rate of 1.27 km2/a,while glacier area de-creased from 167.62 km2 to 141.88 km2 at a rate of 0.86 km2/a. The increasing rate of lake in 1991–2000 was 1.76 km2/a that was faster than 1.03 km2/a in 1970–1991,while in the same period of time,the shrinking rates of glaciers were 0.97 km2/a and 0.80 km2/a respectively. Important factors,relevant to lake and glacier response to the climate,such as air tempera-ture,precipitation,potential evapotranspiration and their values in warm and cold seasons,were discussed. The result suggests that temperature increasing is the main reason for the accelerated melting of glaciers. Lake expansion is mainly induced by the increase of the gla-cier melting water,increase of precipitation and obvious decrease of potential evapotranspi-ration. Precipitation,evaporation and their linkages with lake enlargement on regional scale need to be thoroughly studied under the background of global warming and glacier retreating. | WU Yanhong ZHU Liping | 2008 | Journal of Geographical Sciences2008,18,2: | 42 |
