安徽省生态区生态环境状况的评价研究

Evaluation of ecological environment in ecological area of Anhui Province

选取安徽省5大生态区作为研究对象,参考环保部门对县域生态环境状况评价的相关技术规范,对2011年和2015年安徽省全部县区生态环境状况进行评价;再根据5大生态区所辖的县区,采用配对样本t检验方法进行各生态区进行差异性分析,以评价各生态区的生态环境状况变化情况。通过对各生态区二级指数的统计学分析,找出导致研究年份间变化的原因,为环境管理提供决策支持。

In this paper, five ecological areas of Anhui Province were selected to evaluate the ecological environment in 2011 and 2015 in all counties of Anhui Province based on relevant technical specifications of environmental protection departments. According to the situation of the five ecological areas, the paired sample t test was adopted to analyze the difference of each ecological area, so as to evaluate the changes of the ecological environment in each ecological area. Through the statistical analysis of the second-level index of each ecological area, the reasons for environment changing were obtained. The result could provide decision for environmental management.
