城市化与生态环境协调发展对比分析研究——以青岛、深圳市为例

Comparison Analysis on the Coordinated Development of Urbanization and Ecological Environment System—— A case of Qingdao and Shenzhen

基于青岛市、深圳市2005—2012年数据的基础上,运用主成分分析法和数学离差原理建立城市化与生态环境协调发展模型,对两市城市化综合发展水平、生态环境综合发展水平和城市化与生态环境协调发展状况进行了对比分析.结果表明:城市化发展子系统与生态环境子系统之间存在明显的协调互动关系;相对于深圳市而言,青岛市城市化综合发展水平和生态环境综合发展水平增长迅速,但水平较低;综合来看,青岛市和深圳市城市化与生态环境协调度及协调发展度发展趋势整体良好,但与深圳相比青岛城市化发展子系统和生态环境子系统承载量较小,易受到外界影响,并且其生态环境子系统发展慢于城市化发展子系统.

In this paper, we utilize the principal component analysis and mathematical deviation principle to build a model of the coordinated development of urbanization and ecological environment. Based on 384 indexes of Qingdao and Shenzhen from 2005 to 2012, we use the mode to conduct a comparative analysis between Qingdao and Shenzhen. The conclusion indicates that there is a significantly coordinated interaction between urbanization and ecological environment subsystem. Compared with Shenzhen, the comprehensive development level of urbanization and ecological environment is growing rapidly in Qingdao, but the level is lower. On the whole, the coordination degree and the coordinated development degree of urbanization and ecological environment system are good. However, compared with Shenzhen, urbanization subsystem and ecological environment subsystem carry a smaller amount, and are more susceptible to outside influence, and ecological environment subsystem development is slower than urbanization subsystem in Qingdao.
