摘要

本研究旨在将地理信息系统中的层次分析法应用于摩洛哥阿齐拉尔地区南部的水土流失研究。该方法是规划和管理自然风险的重要工具;它使我们能够获得水侵蚀的多因素敏感性图。研究区侵蚀土壤条件敏感性图显示,6%的区域处于(较低)侵蚀风险中,85%的区域处于中等侵蚀风险中,仅8%的区域处于高度水风化因子暴露中。从视觉上看,高风险区域对应于“Oued Lakhdar”及其支流周围地区。

Application of The Hierarchical Multicriteria Analysis Method to The Study of Water Erosion (South of Azilal, Morocco)
This study aims to apply the process of the analytical hierarchy in geographic information system to the study of water erosion in the southern part of the Azilal region, Morocco. This method is an important tool to be used in the planning and management of natural risks; it has allowed us to obtain a multi-factorial sensitivity map to water erosion. This sensitivity map of erosive soil conditions in the study area shows that 6% of the area is (less) exposed to erosion risk while 85% of the mapped area is moderately exposed to erosion risk and only 8% of the mapped area is highly exposed to water weathering factors.  Visually, the high-risk zones correspond to the area around ‘’Oued Lakhdar’’ and its tributaries.
