本文在已有区域水土流失因子研究成果基础上，基于坡面土壤侵蚀机理研究成果和对区域水土流失过程的分析，进行了区域尺度上水土流失模型设计的初步尝试．主要内容如下： 1．在ARCGIS环境下，初步开发了分布式区域水土流失模型； 2．提出了区域水土流失模型计算所需的有关参数及其可行的提取方法； 3．通过利用典型流域数据进行计算，结果接近现实的土壤侵蚀时空分布趋势和分异．

英文摘要：

This thesis preliminarily attempts to design the pattern of the soil erosion on large size, according to the researching accomplishment on the reason of corroding the soil on the slop and the analysis of the process of the regional soil erosion, in view of the researching accomplishment on the reasons of the regional soil erosion patter. The main contents in the following： 1. According to the description of the process of soil erosion on the size of slope, under the ArcGIS, exploiting preliminarily the pattern of the regional soil erosion respectively. 2. Put up the method about to distill the parameter of the pattern of soil erosion in regional size. 3. According to using the concrete data of the basin to calculate, the result reflects the tense and spatial tendency and difference of soil erosion, which accord with the reality.
