| 摘 要： | 阜阳市作为地面沉降的典型城市,近年来,地面沉降已成为阻碍城市发展的重要地质环境问题。研究结合阜阳市现行地质条件,从地面沉降现状、自然因素与人类活动三个方面建立适用于阜阳市的地面沉降危险性评价指标体系,从地面高程、人口密度、单位面积GDP、工程重要性分布4个方面建立易损性评价指标体系共同组建风险性评价指标体系,引入层次分析法-综合指数法完成阜阳市地面沉降风险评价。依据评价结果提出针对性防控建议,取得的研究成果可为阜阳市国土空间开发规划与社会经济发展提供地学依据。

| Abstract: | Land subsidence is a typical geological environment problem that hinders urban development of Fuyang city.According to the geological conditions of Fuyang City,the present situation of ground subsidence,natural factors and human activities were mainly taken into consideration to establish the risk evaluation index system of ground subsidence.The vulnerability evaluation index system is established considering the ground elevation,population density,unit area GDP and engineering importance distribution,the risk evaluation index system was also established.Then the analytic hierarchy-composite index method was adopted to assess the risk of land subsidence.Finally specific suggestions on land subsidence prevention and control are put forward,and the research results can provide reference for land space development planning and social and economic development of Fuyang City. |
