The Remote Sensing Investigation of the Secondary Geological Hazards Situation in the West Mountain Area of Qingchuan County in Sichuan Province and Suggestions Concerning Prevention and Control

选择汶川地震重灾区之一且有代表性的青川县西部山区为研究区,分析了特殊构造部位与次生地质灾害的关系,建立了次生地质灾害遥感解译标志,总结了该区次生地质灾害的主要类型,评价了该区的灾情现状,并提出了合理防治的建议。

In this paper, the west mountain area of Qingchuan County, one of the most serious earthquake hazards areas in Wenchuan County with representative significance, was chosen as the study area. The relations between the special structural position and the secondary geological hazards were analyzed, the remote sensing interpretation keys to the secondary geological hazards were established, the predominant types of the secondary geological hazards in this area were summarized, and the hazards situation in this area were estimated. On such a basis, some reasonable suggestions concerning the prevention and control of such hazards are put forward.
