基于系统行为的城乡耦合地域空间演变规律研究——以南京市为例

在总结国内外城乡双系统相互作用动力机制研究的基础上,论文引入城乡耦合地域系统非线性动态模型,通过耦合度揭示各系统要素在城乡耦合界面上相互作用的机理、过程.并以南京为例,运用主成分分析法从28项指标中提取经济发展水平、社会协调程度、资源设施配给率、环境负反馈机制等4项主因子对其进行耦合度实证辨析,得出南京城乡相互作用及不同时期两种扩张所处阶段,进-步明晰了南京城乡耦合地域系统空间演变规律,为科学规划和管理边缘地域提供了参考依据.

The Construction of Interspatial Expansion Modeling about Urban-rural Coupling Region's System——Take Nanjing as an Example

On the basis of interactional dynamic mechanism research about urban-rural double system both at home and abroad,the article constructs non-linear dynamic model of urban-rural coupling region's system according to modern systemic science theories. The introduction about coupling degree concept has underwritten the interaction modes and paths of various essential system elements on urban-rural coupling region's system. Taking Nanjing city as an example, the author choosed 28 indexes and used principal components analytic method to extract four principal factors,such as development level of economy (including traffic element) ,coordinated degree of society, ration rate of resources and facility, negative feedback mechanism of environment and so on, in order to differentiate and analyse the demonstration by coupling degree. This research concluded patulous stages in different periods about the urban-rural mutual affects,viz. seasonal accelerated period,seasonal decelerated period and seasonal immobile-filled period ,besides defined deeply the regulation of spatial evolution about urban-rural coupling region's system in nanjing , and provide theoretical foundation for planning and managing scientifically the region.
