摘要
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。
The method of watershed Survey is adopted to research watershed erosive geomorpy on theLoess area in the west of shanxi,in the words, erosive geomorphic characteristics of watershed are surveyd and measured as the unit of watershed.This Paper analyzed some factors that effect the for-mation of erosive geomorphy,and explored its segregations and divison scheme based on Fuzzy Clus-tern Analysis(selecting 6 factors)of 49 watershed,and also,this divided scheme takes considered of geomorphy, erosive force and forme and other effected factors ,and takes acounted of the division scheme of geomorphy,hydrology and erosion in Shanxi.This study will contribute to probe water-shed comprehensive managment in the kinds of regions in the west of Shanxi.
