    重庆市渝中区地质灾害易发程度分区及评价

    SUSCEPTIBLE DEGREE ZONING ASSESSMENT OF GEOLOGICAL HAZARD IN YUZHONG AREA, CHONGQING

    • 摘要: 针对重庆市渝中区斜坡变形体、危岩崩塌、滑坡等地质灾害,遴选地质灾害发育程度、地形地貌、破坏地质环境的人类工程活动、地质构造、水文及水文地质条件和岩土性质等6个地质灾害的影响因子; 采用基于层次分析法(AHP)的多级模糊综合评价法(FAHP)结合地质灾害综合评价指数法对其地质灾害易发程度进行评价分区,将重庆市渝中区的地质灾害危险性分为4级区,即:高易发区,中易发区、低易发区和不易发区,每区所占面积分别为1.67km2, 4.49km2, 0.83km2, 17.12km2,其结果符合实际情况。研究结果为渝中区的地质灾害防治区划、城市规划、经济发展、生态环境保护以及防灾、减灾提供了必要充分的地质环境依据。

       

      Abstract: For the geological hazard in Yuzhong area, Chongqing such as deformation of slope, unstable rock collapse, slope, select 6 impact factors of geological disasters including the degree of development of geological hazard, topography, human engineering activities which damaged geological environment, geological structure, hydrogeological conditions and geotechnical properties. Use the method which combine FAHP that is based on AHP and geological disaster comprehensive evaluation index to evaluate and zone the geological disaster susceptible degree, and divide the Yuzhong area into 4 parts:high-prone areas, middle-prone areas, low-prone areas and non-prone areas. Their acreages are 1.67km2, 4.49km2, 0.83km2 and 17.12km2. The results are line with the actual situation. The results provide necessary and sufficient geological environment basis for geological disaster prevention zoing, urban planning, econonic development, ecological environmental protection and disaster prevention and mitigation in Yuzhong.
