循环经济指导下的汉中环境熵聚类实证

依据熵增理论,从理论上拓展了环境熵的概念。基于国家汶川灾后恢复重建总体部署中关于建设汉中循环经济产业集聚区的规划,首先对2003—2007年引起汉中环境熵的主要环境污染物排放量与城市化率的变化进行实证分析,然后依据环境熵理论与方法,测度出2003—2007年汉中11个县(区)的环境熵值,并运用系统聚类中的分层聚类方法,借助SPSS软件进行汉中环境熵聚类实证并绘出相应的环境熵聚类图。为落实灾后恢复重建各项任务以及改善和提升地区生态环境质量,结合汉中循环经济产业集聚区的分区规划,从削减地区环境熵的角度考虑,将汉中分为3个不同的类别区,因地制宜地给出各个区在发展循环经济的过程中需要在生态环境保护方面采取的相应对策与建议。

ENVIRONMENTAL ENTROPY CLUSTERING IN HANZHONG UNDER CIRCULAR ECONOMY

 The environment entropy theory has been expanded according to the entropy increase theory. This paper, based on nation’s Hanzhou industrial and economic planning, analyzes the pollute discharge and urbanization ratio changes in 2003-2007, which led to environmental entropy change in Hanzhong, and measures the environmental entropy values in 11 counties (districts), and applies hierarchical clustering method to plot the environmental entropy clustering map via SPSS software. In order to restore reconstruction and improve land environment after earthquake, this paper, combined with circular economic industrial clustering planning in Hanzhong, aims to decrease the environmental entropy value and classifies Hanzhong into three zones, where need relevant suggestions in ecological environment during circular economic development.
