采用流域调查法，以流域为单元进行调查量算，分析了晋西黄土地区流域侵蚀地貌特征、分异规律及其影响因素，选取６个主要特征因子，对４９条典型流域做了模糊聚类分析，同时，充分考虑区域地貌、侵蚀营力和方式及其它因素，并参照山西省地貌、水文、土壤侵蚀分区方案，将晋西黄土地区流域侵蚀地貌划为２个大区，６个亚区，这有助于探索该地区不同区域流域综合治理的模式和途径。
Using watershed investigation method and taking the watershed as a unit to carry out surveys and calculations, the erosional landform features, differentiation rules and their influencing factors in the drainage area of western Shanxi Province were analyzed. Six main characteristic factors were selected and 49 typical watersheds were clustered by fuzzy clustering At the same time, taking into account the regional landscape, erosion power and ways and other factors, and referring to the plan of landform, hydrology and soil erosion in Shanxi Province, the erosional landform in the drainage area of Shanxi Province is divided into two major regions and six sub-regions , Which helps to explore patterns and approaches to integrated watershed management in different regions of the region.
