珠三角地区城市化与生态环境协调发展的动态耦合分析——以珠海市为例

Dynamic Coupling Analysis between Urbanization and Eco-environment in Pearl River Delta: Take Zhuhai as An Example

城市化与生态环境协调发展是影响城市可持续发展的重要方面。为了总结珠三角地区城市化与生态环境协调发展的经验,以珠海市为研究对象,首先,在构建城市化与生态环境指标体系的基础上,利用主成分法综合评价珠海城市化和生态环境水平。其次,根据城市化与生态环境耦合含义和规律,引入动态耦合模型,探讨复合系统耦合度的时间变化特征。结果表明:1996—2011年,珠海市城市化与生态环境水平显著提高;耦合度的变化呈现出先大后小、再变大的"U"型形状,依据其变化特点将其划分为两个阶段。最后,通过分析耦合度变化的原因,为其他城市提供可借鉴的经验。

The issues on the coordinated development between urbanization and eco-environment was key fac- tor to sustainable development of city. In order to summarize the experience in Pearl River Delta, it took Zhuhai as an example and employed principal component analysis to evaluate level of urbanization and eco-environment based on indictor systems. Secondly,with the concept and regularity of coupling situation, it used dynamic model to ex- plore coupling situation＇ s temporal changes in compound system. The demonstration is that the Zhuhai＇ s compre- hensive level of urbanization and eco-environment grows steadily from 1996 to 2011 ;the changes in the degree of coupling situation shapes U,which divides the coupling curve into two stages. Finally,it analyzed reasons of changes in coupling degree to provide experience for other cities.
