基于RS和GIS的皂市水库地质灾害诱发因素分析

Analysis of Geological Hazard Induced Factors in Zaoshi Reservoir Based on RS and GIS

为了分析皂市水库地质灾害的诱发因素,本文借助于遥感(RS)和地理信息技术(GIS),以高分二号卫星(GF-2)影像为工作底图,采用人机交互解译、室内解译和野外查证相结合的方法进行研究区内地质灾害体的解译。同时,提取区内省道S303的分布信息,收集皂市水库库区范围,借助于ArcGIS软件平台,采用多级缓冲区的分析方法,分别对省道S303和库区范围进行缓冲区设置,分析省道和库区对地质灾害发育情况的影响。

In order to acquire the induced factors of geological hazard in Zaoshi reservoir, under the support of RS and GIS, the paper studies the interpretation of geological hazard firstly, taking GF-2 satellite images as working map, and using the methods of man-computer interactive interpretation and the combination of indoor interpretation and field acceptance.Secondly extracts the provincial road S303 distribution and collects the reservoir area.Finally, based on the software of ArcGIS, by the method of multiple ring buffer, analyzes the influence of the province road and the reservoir area on the occurrence of geological hazard.
