Paper Abstract

To study the cause of frequent drought and rainy-flood disasters in Sichuan province in recent years, a method based on remote sensing (RS), geographic information system (GIS) and global positioning system (GPS) is presented to establish land use/cover change (LUCC) database of Sichuan province. Firstly, LUCC was interpreted interactively with the China-Brazil Earth Resources Satellite (CBERS-02) images in 2005, in the light of the database from Landsat-Thematic Mapper (TM) in 2000. Secondly, the interpreted result was validated in the field with GPS hand-held receiver and the database was updated subsequently. Thirdly, LUCC was extracted from the interpreted database with GIS software. The result reveals that the achievement of "grain for green" project was very little, and more farmland? were being occupied; the cities were overspreading at the same time. Therefore, the eco-environment of Sichuan province became worse. Some decisions were provided to improve the eco-environment of Sichuan province at last.
