Abstract:: Employing the Loess Plateau Soil and Water Conservation Research,this paper applies AHP to land use anti-erosion ability of quantitative evaluation.Dividing the land use types into layers of factors and factor layer,combing with expert knowledge,this article quantitative identifies the proportion erosivity of different types of anti-land use.According to land use types with the incomplete structural characteristics and influnced by the number of dominant factor,it amends the proportion of anti-erosion.It calculates the score of anti-erosion ability by the amendments and gets the evaluation results of study area evaluation unit anti-erosion ability.Finally,analyzing the data of different periods in the study area,the author finds that above method is scienticfic and advanced.
