Based on GIS spatial analysis technology,the factors sensitive to ecological environment include mainly the soil erosion,land desertification,soil salinization and biodiversity reduction.The results were as follows:the extremely and highly ecological sensitive are as were dominant in the peripheral regions of the Karamay urban area.The extremely sensitive areas were mainly distributed in the north of Shixi Road,south of Industrial Park,Wuminghu wetland and the piedmont zone of the Jayer Mountain in the west,and their proportion accounted for 37.38% of the study area.The highly sensitive areas were mainly distributed in the vast plains south of Shixi Road expect Wuminghu wetland and some piedmont zone southwest of the Jayer Mountain,and their proportion accounted for 51.71% of the study area.The mildly sensitive and non-sensitive areas were distributed only in the western and northern piedmont zones of the Jayer Mountain,and their proportion accounted for 0.76% only.Holistically,the ecological sensitivity of the study area was high,non-protective development should be strictly prohibited in the high and extremely high ecological sensitive areas.Moderate,mild,and non-sensitive areas should be developed moderately under the concept of ecological priority.
