摘　　要：选取人口环境容量失衡度、年降水量、植被覆盖度、土层厚度、地形坡度、土壤可蚀性、岩性和坡耕地占坡地面积比例等八个因素,作为评价晋北侵蚀区土壤侵蚀潜在危险度的主要因素,利用特尔斐法(Delphi)和层次分析法(AHP)确定8个因子的权重,运用数学模型计算,对晋北侵蚀区土壤潜在危险度进行了评价。Eight factors such as population - environmental capability,annual rainfall,vegetation coverage,soil layer thickness,slope degree,soil erodibility,lithology and percentage of cultivated land in slope - land area,etc. were se-lected for assessing soil erosion potentiality in northern ShanxiProvince. The AHP and Delphi method were used to de-termine the weight of each factor. By applying the mathematic model,it was graded and evaluated the soil erosion po-tentiality in northern ShanxiProvince.
