采用“加权重叠排序方法”，研究了黄土高原腹地的１０６县（旗）、市水土流失的危险程度排序。结果表明，位于长城沿线附近的神木、临县、环县、准旗、定边、子洲、府谷、同心、靖远、靖边、海原、绥德、吴旗、榆林、华池、会宁、东胜、伊金霍洛旗、保德、盐池和横山等２１县（旗）、市，是黄土高原水土流失的危险区域，而位于晋陕蒙接壤地区的神木、府谷、准格尔旗、东胜、伊金霍洛旗和保德等地应是黄土高原水土流失最危险的区域，必须加强监督，监测和加大治理投资力度，处理好资源开发利用与环境保护的关系。
The dangerous degree sequence of soil and water loss is studied which include 106 counties(banners) , cities in the hinterland of Loess Plateau, by use of"weighted plus and lap sequece". Theresult indicated that where existed dangerous area of soil and water loss in loess Plateau which locatedalong the Great Wall, including shengmu, Linxian,Huanxian, Zhongqi, Dingbian, Zizhou, Fugu,Tonxing, Jingyuan, Haiyuan, Suide, Wuqi, Yuling, Huachi, Hnining, Zhonggeer, Dongsheng, Yijinhuoluo, Baode, Yianchi and Hengshan etc. 21 Counties (Banners), Cities. and there was verydangerous area with serious soil and water loss in Loess Plateau which located in the contiguous area ofShanxi, Shaanxi and Inner Mongolia. including Shengmu, Fugu, Zhonggeer, Dongsheng, Yi-jinghuoluo and Baode etc. It mus be strengthened management, monitor and increased investment bythe government with the coordinated development between the use of resource and the environmentprotection.
