摘要:

随着城市化进程的加快,人类工程活动日益强烈,地质环境问题已经成为阻碍绿色城市发展的关键因素。了解区域地质环境承载现状,有助于提出有效的地质环境调控手段,科学指导区域发展规划。以湖北省黄石市为研究区,基于地质环境、生态环境、社会环境三个方面共16个评价指标,构建地质环境承载力评价体系。采用模糊综合评价(Fuzzy Comprehensive Evaluation,FCE)确定各因子的隶属度、层次分析法(Analytic Hierarchy Process,AHP)确定各因子权重,最后通过GIS空间分析对黄石地质环境承载力进行综合评价。研究表明:黄石市东北区域承载力较差,主要受地灾因子制约,建议对地质灾害问题进行修复治理;中西部陈贵镇附近因矿山开采导致其承载力较差,建议开展矿山环境恢复工程;南部阳新县承载力整体较好,可进行适度开发利用。不同区域地质环境承载力的短板要素不同,需要找到制约因子并对其进行改善来提高地质环境承载力。

Abstract:

With the continuous acceleration of urbanization, human engineering activities have become increasingly strong, and geological environmental problems have become a pivotal factor hindering the development of green cities. Understanding the status of regional geological environment carrying capacity can help to provide effective geological environment control measures and scientifically guide regional development planning. We take Huangshi city in Hubei province as the research area, and build a geological environment carrying capacity evaluation system consisting of 16 evaluation indexes of geological environment, ecological environment and social environment. The FCE (fuzzy comprehensive evaluation) is used to determine the membership degree of each factor. The AHP (analytic hierarchy process) is used to determine the weight of each factor. Finally, the GIS spatial analsis is used to comprehensively evaluate the geological environment carrying capacity of Huangshi city. The research indicates that the geological environment carrying capacity is low in the northeast of the study area, which is mainly restricted by the disaster factors. Therefore, we recommended that disasters should be reduced. The geological environment carrying capacity is low in the southwestern part of Chengui town owing to mining over-exploitation. Thus, we recommended that mining environment restoration project should be carried out. The Southern Yangxin county, which has a high geological environment carrying capacity, can be appropriately developed and utilized. Generally, we should take targeted measures to improve geological environment carrying capacity in different parts of the study area.
