摘要
通过对城市生态系统和对城市生态系统的耗散结构进行熵变演化分析,构建了城市生态系统可持续发展能力评价指标体系;借鉴热力学第二定律中的熵变方程原理,运用信息熵构建了城市生态系统可持续发展能力评价模型;并以南京市为例,对南京市城市生态系统可持续发展能力进行实证研究,结果表明:2005~2012年南京市经济社会的发展对其城市生态系统带来了沉重的压力,但在政府部门的重视下,南京市城市环境污染问题业已得到有效的治理,南京市城市生态系统的生态承载能力在曲折中逐步上升,并呈现出逐步好转的趋势,对经济社会发展的支撑能力不断增强,已走在可持续发展能力不断增强的轨道上。
Based on evolution analysis of urban ecosystem and its dissipative structure, this paper established evaluation index system of urban ecosystem sustainable development capacity. The sustainable development capacity evaluation model of urban ecosystem was built based on the entropy change equation in the second law of thermodynamics and information entropy theory, taking Nanjing as an example, this paper empirically studies the Nanjing's urban ecosystem sustainable development capacity. The results showed that: from 2005 to 2012, Nanjing's urban environment pollution has been effectively eliminated; Nanjing's urban ecosystem has developed in an orderly and healthy direction; the carrying capacity of Nanjing's urban ecosystem has been showing an upward trend. The quality of ecological environment has been improved and the ability of the urban ecosystem to support the urban socioeconomic ecosystem increased continuous.
