| 本文利用专家-层次分析法对地质灾害风险性进行评价,以广西贺州市富川瑶族自治县地质灾害风险调查评价为依托,通过资料分析和现场调研,根据各类地质灾害构建其风险性评价指标体系,采用专家-层次分析法对地质灾害风险性进行研究,研究结果表明:将富川瑶族自治县地质灾害风险分区分为高、中、低3种类型,富川瑶族自治县面积为1572.5 km2,其中地质灾害高风险区(I)的面积约为166.37 km2,约占研究区面积的10.58%；地质灾害中风险区(II)的面积为167.37 km2,约占研究区面积的10.64%；地质灾害低风险区(III)的面积约为1238.76 km2,约占研究区面积的78.78%。借助GIS平台实现可视化,评价结果对广西地区地质灾害的防治具有指导意义。 |
| 英文摘要: |
| In this paper, using expert-analytic hierarchy process (ahp) to evaluate the geological disaster risk, in Fuchuan County geological disaster risk data from field investigation and evaluation results as the basis, through data analysis and field investigation, according to different types of disasters, selecting the different evaluation factors, created the geological disaster risk evaluation index system. The expert-analytic hierarchy process is used to study the risk of geological disasters. The results show that:The geological hazard risk of Fuchuan Yao Autonomous County was divided into three types:high, medium and low. The area of Fuchuan Yao Autonomous County was 1572.5 km2, and the area of high risk area (I) of geological hazard was about 166.37 km2, accounting for 10.58% of the study area. The area of risk area (II) in geological disasters is 167.37 km2, accounting for 10.64% of the study area. The area of low risk area (III) of geological hazards is about 1238.76 km2, accounting for 78.78% of the study area. With the help of GIS platform to realize visualization, the evaluation results have guiding significance for the prevention and control of geological disasters in Guangxi. |
