摘    要:以东圳库区的法国SPOT-5遥感影像和相关图件为源数据,以影响水土流失的土地利用类型、地貌、坡度、坡向、土壤等景观因子为研究对象,运用GIS技术,提取各因子特征信息,采用侵蚀强度系数、多样化指数、集中化指数3种数值评价指标方法,分析各景观因子类型的水土流失强度分异特征与变化规律,为库区重要水源地水土流失综合治理及景观因子的生态调控提供科学依据.

Abstract:Based on the remote sensing SPOT-5 reflection picture and some other pictures of Dongzhen reservoir watershed,concerned with studying the landscape factors affecting soil and water loss, such as landuse, landform, slope, aspact slope, soil, and so on, the author extracted information of the landscape factors characteristics and chose three evaluation methods; the intensity coefficient of soil and water loss,index of diversification and centralisation of factor types, analyzed the characteristic discrepancies and change laws of soil and water loss,in order to supply some scientific basis to Dongzhen reservoir watershed for controlling soil and water loss and adjusting ecologic structure.
Keywords:GIS  Dongzhen reservoir  soil and water loss  landscape factors
