中文摘要：

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：1，基于坡面尺度上对水土流失过程的描述，并将区域尺度水土流失的过程划分为水和沙两个子过程．2，从能量和物质平衡的角度考虑区域尺度上的水土流失过程．根据能量平衡过程，建立了相关的数学模型．3，在ARCGIS环境下，初步开发了分布式区域水土流失模型．通过利用具体流域数据进行计算，结果反映了接近现实的土壤侵蚀时空分布趋势．

英文摘要：

This thesis made a preliminary attempt to design the patterns of the regional soil erosion, based on its former research accomplishments of the regional and sloping soil erosion as well as the analysis of its process. The main contents were as follows： 1）. To divide the regional soil erosion into two sub-processes of water and sand, according to the description of the process of sloping soil erosion;2）. To build up the relevant mathematical patterns, taking the process of the regional soil erosion into consideration, from the angle of the balance of energy and material; 3）. To exploit preliminary patterns of the regional soil erosion, in view of ArcGIS, according to the concrete calculation data of the basin. The result showed the space-time distribution tendencies and differences of soil erosion came to as near as the reality.
