基于AHP的山东半岛生态环境承载力模糊综合评价

Abstract

本文结合山东半岛生态环境现状，依据指标体系建立的原则，通过对指标的筛选，将山东半岛生态环境承载力指标体系划分为自然环境、生态环境、人口环境和污染环境四类一级指标，每类一级指标各选择其典型二级指标构建了18项评价指标作为生态环境承载力的评价体系，用层次分析法(AHP)确定了各个评价指标的权重，然后将模糊综合评价模型的理论和方法应用于山东半岛生态环境承载力的评估，对现阶段山东半岛6个城市的生态环境承载力做出评价。评价结果为威海市生态环境承载力为I级优，青岛、烟台、日照市为II级良，潍坊市为III级一般，东营市为IV级差，并对每个城市的生态环境承载力做了分析说明，以期为推进生态文明建设提供科学依据。 In this paper, we combine Shandong peninsula actual conditions with the principle of the evaluation index system, and evaluation index system of eco-environmental carrying capacity of Shandong Peninsula was established. The evaluation index system has been divided into four primary indexes: natural environment, ecological environment, population environment, contaminated environment. The evaluation index system used 18 typical evaluation indexes as secondary indexes which we choose from the primary indexes; the weight of each evaluation index is determined by AHP, and we adopt fuzzy comprehensive judgment to assess the eco-environment carrying capacity of six cities in Shandong Peninsula at the present stage. The results are: Weihai city is first rate, Qingdao, Yantai, Rizhao cities are secondary rate, Weifang city is tertiary rate, Dongying city is poor rate. Based on the evaluation results and analysis of each city, we provide the scientific basis for the eco-civilization construction.
