摘　　要：以四川省珙县为例,探讨了以GIS技术为支撑的区域崩塌、滑坡易发性评价的基本思路和技术路线;对评价指标的选取作了概括的分析和说明,认为其预测评价因素分为基本因素和诱发因素2大类;采用模糊综合评判方法对崩塌、滑坡的易发性进行评价,并在模糊综合评判方法的具体应用、评价指标隶属度的确定以及权重确定等方面也作了分析和阐述;对珙县区域崩塌、滑坡的易发程度讲行了评价,结果与实际较为吻合。In this paper,the method of areal landslides susceptibility assessment with GIS has been discussed.Analyze and explaine hotw to choose the assessment indexes which are divided into two kinds:basic factors and induced factors.Landslide susceptibility has been analyzed with fuzzy comprehensive assessment.The application,ensuring indexes subjection degree and quotient have also been worked out.In Hong County,the authors analyzed landslide susceptility with above method.The result is consistent with the fact.This method can be put in practice in geology hazard investigation.
