英文摘要: In Southeast of Yunnan Province, rock-desertification is an urgent and important land degradation problem which need to be survey and studied by science method and technique application. Aim at rock-desertification dynamic change information obtain, sensitivity evaluation and process simulation analysis, this project research work will be carried into execution. Supported by technique integration application of remote sensing(RS) and geographic information system(GIS), based on the analysis understand on rock-desertification dynamic change condition and its dominant impact fators, combine with land ecology system theory and press-state-response(PSR) analysis framwork, explore rock-desertification spatial and temporal variation features in Southeast of Yunnan Province, and get cognition on relation mechanism between landuse and rock-desertification. Next, by use of GIS spatial analysis and data process technique, based on multi-source information synthesis use to evaluate rock-desertification environment sensitivity, get cognition on sensitivity features and mechanism, continuely carry through research on rock-desertification dynamic evolution process and development trend analysis by GIS model technique, and get rock-desertification dynamic mechanism. Finally, base on theory and measure application of land use
