摘　　要：土壤侵蚀敏感性分析是生态敏感性评价的一项重要内容。基于ArcGIS软件平台,采用综合指数法对山东省土壤侵蚀敏感性状况进行了综合评价。研究显示,山东省存在不同程度的土壤侵蚀敏感性,其中中度及中度敏感以上区域占全省总面积的25.21%,这些地区易于发生土壤侵蚀;极敏感和高度敏感区主要分布在鲁中南山区、胶东低山丘陵区和黄泛平原区。进一步指出,加强植被保护、发展生态农业是推进生态敏感区环境保护的重要手段。Sensitivity analysis of soil erosion is one of significant contents that relate to ecological susceptive assessment. On the basis of ArcGIS software, it utilizes the method of comprehensive index to completely appraise the status of soil erosion sensitivity in Shandong province. There are various kinds of sensitivities of soil erosion in regions of Shandong province, within them the regions that are moderate and high sensitivity of soil erosion account for 25.21% of total area of whole province, these regions are easily subject to produce soil and water loss; extreme and high sensitivity of soil erosion is mainly distributed in these regions such as hills of Luzhong-South, highlands of Jiaodong and Yellow Plains. As a result, it suggests that strengthening the protection of vegetation and developing ecological agriculture should be the significant measurement that is responsible for environmental protection in ecological susceptive regions of Shandong province.
