摘　　要：运用GIS空间分析技术,选取土壤侵蚀、土地沙漠化、土壤盐渍化、生物多样性4个生态环境因素进行敏感性评价。结果表明：克拉玛依市中部城区外围以极敏感、高度敏感为主,极敏感区主要分布在克拉玛依市外围的石西公路北部、工业园区南部、无名湖湿地以及西部加依尔山山前地带,占37.38%;高度敏感区主要分布在石西公路以南除湿地外的广大平原区及西南部加依尔山山麓的部分区域,占51.71%;轻度敏感区和非敏感区零星分布在西部和北部加依尔山前,仅占0.76%。研究区生态敏感性整体偏高,极敏感及高度敏感区域应严禁非保护性开发,中度、轻度敏感区域应在生态优先的理念下适度开发。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.
