摘要:
依托黄土高原水土保持研究，将层次分析方法引入到土地利用抗侵蚀力定量评价中，提出把土地利用类型划分为因素层和因子层，并运用层次分析方法，结合专家知识，定量确定了不同土地利用类型的抗侵蚀力比重，并且根据土地利用类型具有不完全的层次结构特征，同时考虑到土地利用类型支配因素数目的影响，进一步对所确定的抗侵蚀力比重进行修正，并运用修正结果对各地类的抗侵蚀能力得分进行计算，得到研究区域10m×10m评价单元的抗侵蚀能力评价结果。最后将本地区不同时期的数据进行对比分析，验证了本方法的科学性和先进性。
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.
