摘　　要：以延河流域水土保持效益评价系统为例,分析了当前水土保持工作中应用GIS平台获取降雨侵蚀力因子图层的困难,提出结合水土保持工作特点,利用组件式GIS平台ArcGIS Arcobjects进行二次开发,可快速、有效的获取降雨侵蚀力因子图层,并详述了实现的过程、方法和手段。With evaluation system on soil conservation benefit of Yanhe river basin as an example, the diffeulty of obtaining map layer of erosivity factor of rainfall with GIS plaffoma in present soil and water conservation work was analyzed. Combined with the characteristics of soil and water conservation work, secondary development with component GIS platform ArcGIS Arcobjects could quickly and effectively obtain map layer of erosivity factor of rainfall was proposed, and the realization process, method and means were introduced in details.
