山东半岛蓝色经济区地质环境特征分析及其承载力评价研究

Study on Geological Environment and Evaluation of Capacity in Shandong Peninsula Blue Economic Zone

该文从水文地质、工程地质和环境地质3个方面对地质环境进行了重点分析,同时选取14个重要影响因子,搭建地质环境承载力评价指标体系,利用AHP求取各指标权重,借助GIS软件空间叠加功能,计算半岛蓝色经济区地质环境承载力大小,并将其分为5个等级,评价结果显示,地质环境承载力以强区和较强区为主,承载力强区主要分布在胶莱盆地以东海阳市至荣成市沿海一带,差区分布范围较小,主要分布在潍坊市北部沿海地区,文中对各个分区的特征进行了分析研究。

In this paper,geological environment has been analyzed from three aspects as hydrogeology,engineering geology and environmental geology. Selecting 14 important factors at the same time,capacity of geological environment evaluation index system has been built. By using AHP,each index weight has been gained. By using space overlay function of GIS software,geological environment carrying capacity of Peninsula Blue economic Zone has been calculated and divided into five levels. As showed by the evaluation results,geological environment carrying capacities are composed of strong areas and stronger areas. Strong bearing capacity areas mainly distributed in coastal areas of Haiyang city and Rongcheg city in the east of Jiaolai basin. The scope of poor bearing areas is small,and mainly distributed in the northern coastal areas of Weifang ctiy. Characteristics of each partition have been analyzed.
