摘要
地质环境对区域发展有一定的先决作用。山东省地质环境条件比较复杂,存在崩滑流、采空塌陷、地面沉降、海水入侵等地质环境问题,区域开发不能突破其承载力。地质环境承载力是一个动态变化过程,既要考虑地质环境基础条件,也要重视其承载现状,基于此才能科学评估地质环境承载力。本研究在分析区域地质环境特征的基础上,围绕“承载基础-承载现状-承载潜力”模型,建立地质环境承载力评价指标体系,利用AHP和arcgis10空间分析功能对研究区地质环境承载力进行综合评价,最后获得研究区地质环境承载力评价结果。结果表明:沂沭断裂带附近、莱州湾一线、胶州湾一带以及黄河三角洲地区地质环境承载基础弱,其余地区承载基础较强;鲁西地区、烟台市北部地区受采矿活动以及地下水超采等人类活动影响,地质环境承载现状处于超载。包括鲁西北、鲁西南以及胶东半岛的山东省大部分地区承载潜力大。针对影响区域地质环境承载力的重要因素,提出相关对策建议。
The geological environment is a prerequisite for regional development.There are such geological environmental problems as landslides,goaf collapse,ground subsidence,and seawater intrusion etc.Regional development cannot break the bearing capacity of geological environment.The bearing capacity is a dynamic changing process.It is necessary to take into consideration both the basic conditions of the geological environment and the bearing status.Through the analysis of regional geological environment characteristics,this paper builds an evaluation index system of bearing capacity of geological environment on the basis of the“bearing foundation-bearing status-bearing potential”model.A comprehensive evaluation were finally obtained by using AHP and arcgis10 spatial analysis functions.The results show that:the carrying capacity is quite weak near the areas of the Yishu fault zone,the Laizhou Bay,the Jiaozhou Bay,and the Yellow River Delta;in the western part of Shandong and the northern Yantai,the bearing status is overloaded due to human activities such as mining and groundwater over-exploitation.The northwest,southwest and most parts of Jiaodong Peninsula have a large capacity of bearing potential.Some relevant countermeasures and suggestions are proposed in the end.
