摘要
本文首次采用流域调查法研究晋西黄土地区流域侵蚀地貌，即以流域为单元对流域侵蚀地貌特征进行调查和量算，并在此基础上，详尽分析了影响侵蚀地貌形成的地质、地面组成物质、沟道纵坡、降雨、风及人为等因素，探讨了晋西黄土地区流域侵蚀地貌的分异规律（据水平分异规律划分四个区，据垂直分异规律划分了五个带），为该区域流域综合治理提供可参考的理论依据。
The method of watershed survey is first adopted to research into watershed erosional geomorphy on the loess area in the west of Shanxi,in other words,erosional geomorphic characteristics of watershed are surveyed and measured as the unit of watershed. This paper analyzed some factors such as geology,composed material in surface,gully gradient,rain, wind and human that effect the formation of erosional geomorphy,and explores ed its segregational law.The west of Shanxi is divided into five erosional geomorphic belts based on vertical law and four regions based on level law.It posed theoretical foundation for reference to watershed comprehensive management of this region.
