摘　　要：生态敏感性评价是进行生态规划的重要依据,本文以遥感影像和生态环境调查数据为基础,选取具有代表性的8类生态因子并确定其对生态环境影响的分级标准和权重,使用GIS技术,运用加权叠加的方法,对枣庄市台儿庄区生态敏感性进行评价。通过模糊聚类和小面积图斑自动归类合并处理,将区域土地生态敏感性划分5类。研究结果表明:台儿庄区生态极度敏感区占全区面积的7.04%,高度敏感地区占全区面积的8.5%,中度敏感区占全区面积的21.63%,轻度敏感区占全区面积的51.02%,不敏感区占全区面积的11.82,生态敏感性总体较低。On the basis of the remote sensing and ecological survey data,this article selected 8 categories of typical ecological factors,defined the grades and weight of their impact on the ecological environment,and used GIS and Weighting stack in order to assess the ecological sensitivity of Taierzhuang.It divided the regional ecological sensitivity of land into 5 categories by fuzzy cluster and automatic classification and merging of small patches.The results showed that：there were 15.54% extremely ecological sensitive areas and highly ecological sensitive areas in Taierzhuang,and there were 51.02% lowly ecological sensitive areas.The ecological sensitivity in Taierzhuang totally was low.
