摘　　要：水土流失重点防治区划分是提高水土流失防治成效的重要途径。在江苏省水土流失现状综合调查的基础上,采取定性和定量相结合的分析方法,利用ArcGIS等技术手段,科学合理地进行了新一轮江苏省水土流失重点防治区划分,获得了江苏省水土流失重点防治区划分成果图。分析结果表明,江苏省土流失重点防治区包括水土流失重点预防区和水土流失重点治理区,面积35 929km2,占江苏省总面积34.96%。其中水土流失重点预防区面积21 934km2,占江苏省总面积21.32%,水土流失重点治理区面积13995km2,占江苏省总面积13.64%。Regionalization of the key preventing and controlling area of soil and water loss is an important way to improve the effectiveness of prevention and controlling.By combining qualitative method with quantitative method and using technical means such as ArcGIS,a new round of regionalization of the key preventing and controlling area of soil and water loss in Jiangsu Province is carried out scientifically based on a comprehensive survey of the status of soil and water loss and obtained a map of regionalization of the key area.Results show that the key preventing and controlling area in the province consists of key preventing area and key controlling area,with a total area of 35 929km2 that accounting for 34.96%of the whole province.The two key areas are 21 934and 13 995km2,accounting for 21.32%and 13.64% of the whole province,respectively.
