笔者对鄂尔多斯市的8个旗县区开展基于土地生态安全的生态环境敏感性评价,揭示区域生态环境敏感性差异及其影响因素。运用fragstats景观分析法、GIS空间分析法和遥感影像分析法,结合地面调查,采用信息挖掘和数据分析等方法提取研究区域内每一个行政村的指标数据,进行定量化综合评价,最终计算研究区域的生态环境敏感性综合分值。得出鄂尔多斯市的高度敏感区域和极敏感区域主要集中在东部丘陵沟壑区和南部毛乌素沙漠区的中东部地区。究其原因主要有：东部丘陵沟壑区有些地区的水土流失现象严重导致该地区的敏感性较高;南部毛乌素沙漠区的土地沙化现象严重导致其敏感性较高;对于处在这两个区域的村镇来说,加强当地的生态环境保护已经迫在眉睫。

This paper is an evaluation of the ecological sensitivity in the eight banners,counties and districts in Ordos based on the land ecological safety.It＇s a revelation of the regional differences in ecological sensitivity and the influencing factors.Fragstats＇ view analysis,GIS spatial analysis and remote sensor film analysis are applied to the study with the ground survey.We get the index data of every administrative village through information investigation and data analysis to make quantitative comprehensive evaluation and calculate the comprehensive score of the ecological environment sensitivity in the specific area.It is found that the area of high sensitivity and extremely sensitive areas are mainly in the hilly and gully regions in the east and the mid-east part of Mu Us desert in the south.The reasons are the soil and water loss in the east and desertification of land in the south.It＇s urgent to enhance the protection of the ecological environment in the villages in these two regions.
