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.
