基于AHP和GIS耦合模型的山东半岛地质环境承载力评价

Evaluation of Geo-environmental Carrying Capacity in Shandong Peninsula Based on AHP and GIS Coupling Model

地质环境承载力评价是资源环境承载力研究的重要内容之一,也是可持续发展研究的重要应用方向,是践行生态文明建设的具体体现。本文结合山东半岛地质环境现状和特点,构建了基于水文地质环境、工程地质环境和环境地质问题的共12项评价指标的地质环境承载力评价指标体系,采用层次分析法(AHP)确定各个评价指标的权重,采用综合加权指数方法,借助GIS空间分析及属性库链接相结合的方法对现阶段山东半岛地质环境承载力进行了评价。评价结果将山东半岛地质环境承载力的划分为4个等级,并对每个等级区域做了分析说明,以期为推进生态文明建设及可持续发展提供科学依据。

Geo-environmental carrying capacity evaluation is an important topic of resources and environment carrying capacity research,and it is an important research direction of sustainable development and an exemplification of ecological civilization. In this paper,The evaluation index system of geo-environmental carrying capacity of Shandong peninsula was established combining with actual conditions and characteristics. the evaluation index system was been divided into three primary indexes,which are hydrogeological environment and engineering environment and environmental geological problems. And the evaluation index system used 12 typical evaluation indexes as secondary indexes,the weight of which are determined by AHP. We adopted weighted composite index method and combined GIS spatial analysis with data attributes database management method to assess the geo-environment carrying capacity of Shandong Peninsula at the present stage. We divided the geo-environmental carrying capacity into four level. Based on the evaluation results and analysis of each rate area,and then we provided the scientific basis for the eco-civilization construction and sustainable development.
