Abstract
Theoretical basis, methods and techniques and typical case study are related. The core is to test and build a number of geo-information models, such as remote sensing dynamic monitoring models, GIS analysis and evaluation models, as well as statistical models and systems simulation model. With the remote sensing images extracting technology, we discussed the vegetation coverage model and soil erosion model. Comprehensive ecological security evaluation models based GIS is established, making the analysis processes and evaluation results visualized. System dynamics is used in Xishuangbanna ecological security system, dynamics models are established. Through adjusting system parameters, three schemes are simulated and In co-ordination of economic, social and ecological benefits, specific control measures of Xishuangbanna ecological safety are brought out.
