Finally landscape classification maps of the five years would be converted into gray scale images which would be used for overlay analysis, and based on this, landscape ecosystem sensitive zone had been identified. The result showed that the extremely sensitive zone took up 10.18% of the study area and sensitive zone occupied 17.95% of the study area. Ecological system of natural landscape in the lower reaches of Tarim River was superior to ecological system of artificial landscape in terms of resistance to wind, dust, salt and drought. Study on division of ecosystem sensitivity area of natural landscape not only provided scientific reference for the formulation of regional policies to prevent and treat ecological environmental problems, but also was beneficial for people to identify treatment focus of ecological environmental problems in different regions and propose countermeasures ameliorating regional ecological environment.展开更多
