基于EES-物元模型的淮南市土地生态安全评价

Land Ecological Security Evaluation in Huainan Based on EES-matter Element Model

构造基于经济-环境-社会(EES)概念框架的土地生态安全评价指标体系,借助熵权法进行赋权,运用物元分析法构建土地生态安全综合评价模型,对淮南市作土地生态安全评价。评价结果表明:淮南市2010年、2013年和2016年的土地生态安全评价等级均为"一般安全"等级。研究可知:环境脆弱性一直是资源型城市面临的一大难题,淮南市在发展社会、经济的同时,更要致力于环境系统的绿色健康,从而提升土地生态安全等级。

A land ecological security evaluation index system based on the conceptual frameworkof economic-environmental-social （EES） was constructed. With the help of entropy weight method,a comprehensive evaluation model of land ecological security was established by using matter -element analysis method. The land ecological security of Huainan City was evaluated. Theevaluation results showed that the land ecological security evaluation grades of Huainan in 2010,2013 and 2016 were ＂general security＂ grade. The study concluded that environmental vulnerabi-lity has always been a major problem faced by resource-based cities. While developing society andeconomy, resource-based cities should devote more to the green health of the environmental syst-em, so as to enhance the level of land ecological security.
