Eco-environment sensitivity evaluation is recognized as the core issue of eco-environment of Tulasu area in Weastern Tianshan Mountain.The sensitivity of ecosystems in this area were analyzed with regard to soil,vegetation,climate,topography and other natural ecological factors.Based on the remote sensing(RS) technology,land use,pasture use and other information were extracted through image processing and interpretation.Based on GIS spatial analysis functions and the analytic hierarchy,the various factors affecting ecological sensitivity were combined by weights,and a synthesized sensitivity index was obtained.Based on the in-depth analysis of the ecological problems and their forming factors,some measures and suggestions were proposed to improve the ecological sensitivity.The results showed that the eco-environment sensitivity of Tulasu area could be divided into five categories,i.e.,non-sensitive area,mildly sensitive area,moderately sensitive area,highly sensitive area and extremely sensitive area.In addition,this study could provide scientific reference and technical support for the study of ecological environmental protection and the rational development of tourism resources and mineral exploitation.
