Abstract :
Land use/land cover change (LUCC) as an important part of global environmental change has always been one of the hottest issues of ecology research. Based on RS and GIS methods, land use information for 1990 and 2008 was acquired from TM images and analyzed in Yanqing County, Beijing, China. This paper analyzes spatial-temporal land use change in two basins covering the study period. The results showed that, the land use pattern changed dramatically in the past 20 years, and mainly concentrated in Guishui River Basin. The investigation indicated that it is water resource reduction and the increased water pollution caused by land use change which resulted serious water shortage for agriculture irrigation.
