| 摘 要： | 以福建长泰已发生地质灾害为例，选取相对高差、流水地质作用、过程降雨量、地形坡度、岩土体类型、断裂构造、道路开挖堆填、已有地质灾害等7个评价因素，采用模糊数学评判方法，运用GIS平台进行指标取值、分级与成图，最后完成地质灾害危险性评价。经验证，定量评价与定性评价结果较吻合，证明基于GIS的地质灾害危险性评价是切实可行的，结论是可信的。

| Abstract: | Taking Changtai county in Fujian province as example, selected relatively elevation difference, geological process of water flow, process rainfall, terrain slope, rock soil mass types, fault structure, road excavation, happened geohazards as evaluation factor. The fuzzy judge way is applied to evaluation, and GIS is effectively adopted in picking up indication value and making chart, at last. we can take the result of geohazards risk evaluation. Through verification, these evaluation systems are viable. |
