摘　　要：利用遥感(RS)技术提取土壤侵蚀信息,在地理信息系统(GIS)支持下,借助数据库管理系统(DBMS),建立空间数据库和属性数据库;以县级行政区域为综合分析单元,计算土壤侵蚀强度综合评价指数并进行分级处理,对山东省土壤侵蚀空间特征进行分析。Soil erosion is one of the most serious problems of environment. Soil erosion in Shandong Province is so serious that it is of great scientific and practical significance to research on it. In view of the serious environment situation of soil erosion, the spatial features of soil erosion in Shandong Province is analyzed by the unit of county in this paper. The main points are as following: ① Based on the classification index system of soil erosion type and intensity, the classification standards and the features of Landsat TM images are put forward. ② With the support of Geographical Information System (GIS), Remote Sensing (RS) and Database Management System (DBMS), the soil erosion information is distilled from Landsat TM images, the spatial and attribute databases are also built.③　On the basis of the model of IEISEI (Integrative Evaluation Index of Soil Erosion Intensity), the indexes are calculated and classified into eight degrees by the unit of county. ④The spatial features of soil erosion in Shandong Province are analyzed, the soil erosion is very serious and there are two erosion centers in Shandong Province.
