Study on ecological environment quality comprehensive evaluations and countermeasures based on GRAY of Anhui province

利用灰色系统综合评价法(GRAY)对安徽省城市生态环境质量进行综合评价。通过参考相关研究文献比较筛选评价指标,构建城市环境质量评价指标体系,用Delph法确定评价指标权重,结合2013年安徽省统计年鉴数据资料,对安徽省城市生态环境质量进行综合评价,得出城市生态环境质量综合排序。研究结果表明安徽省南部城市生态环境质量较好,北部城市生态环境质量较差,尤其是安徽省两淮煤炭资源型城市生态环境质量综合排名处于最后,对两淮煤炭资源型城市生态城市建设存在的问题进行分析,并提出了相应的对策建议。
