【摘要】 土壤侵蚀是全球面临的严重问题,对人类可持续发展构成了很大的威胁,有关土壤侵蚀危险度评价的研究显得越来越重要,而方法的应用是进行土壤侵蚀危险度评价研究的基础与关键。因此,对目前土壤侵蚀危险度评价研究常用的一些方法,包括土壤抗蚀年限法和侵蚀因子权重评分法(基于USLE的评价方法、模糊综合评价法、层次分析及改进的层次分析法、加权重叠排序方法以及灰色关联度分析法)进行了分析与探讨,以期为今后的土壤侵蚀危险度评价研究工作提供参考依据。更多还原

【Abstract】 soil erosion is a serious global problem,it threats the sustainable development of humankind,so the research of soil e- rosion danger assessment is becoming more and more important.Using of the method is key and base of the research of soil ero- sion danger assessment,but there are few papers related to research of the comparison and applicability of soil erosion danger assessment method.So the article has analyzed and discuss soil erosion danger assessment methods which are often used,inclu- ding fixed number of year of soil-resistant method and marking method of the weight of erosion factor (the assessment method based on USLE,Fuzzy Integrated Evaluation,Analytical Hierarchy Process and improved Analytical Hierarchy Process,Weigh- ting Overlapping Ordering method),providing the reference for further assessment of soil erosion danger.更多还原
