By introducing advanced views of terrain representation and in-terpolation algorithm from western and improving the DEMs based on higher accuracy hypsog-raphy data and digital topography maps,taking scaling issues into account and integrating the existed researches on erosion terrain factors and regional soil erosion model,are key issues in this study field in the future.
DEM在区域土壤侵蚀中应用研究主要包括:如何实现对侵蚀区地形的表达,使之能准确、科学和有效地表达地形形态和侵蚀沟道网络结构;在多种尺度上,用什么指标实现表征地形对土壤侵蚀发生过程的影响;用什么方法提取或者处理地形因子,如何建立地形因子与土壤侵蚀关系。
3) Regional Soil Erosion Model
区域土壤侵蚀模型
1.
Design of the regional soil erosion model based on GIS
基于GIS的区域土壤侵蚀模型设计
2.
And soil erosion evaluation criteria of the Ministry of Water Resources, the Regional Soil Erosion Model and the Chinese Soil Loss Equation were adopted to qualitatively and quantitatively evaluate the dynamic changes of soil erosion of the study area.
基于区域土壤侵蚀模型和中国土壤流失方程表明,2005年土壤侵蚀比1997年土壤侵蚀强,主要是因为2005年的降雨强度远大于1997年,降雨是土壤侵蚀的主要因子之一。

补充资料：差异侵蚀瀑布
差异侵蚀瀑布。当两种不同抗冲能力的岩层在一起，并同时受到一条河流的冲蚀，则会产生差异侵蚀型瀑布。我国的大多数瀑布都是由差异侵蚀造成的。
