摘要 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,本文依据现代系统科学理论引入城乡过渡地区即城乡耦合地域系统非线性动态模型,提取耦合度指标以反映整个系统演化状态以及系统内城市主关联系统与乡村主关联系统在耦合界面上相互作用的协调程度。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、环境负反馈机制等四项主因子对其进行耦合度实证辨析,以此了解南京城乡耦合地域系统演化规律性,为进一步深化科学规划和管理该地域的理论实践提供了借鉴。 On the basis of summarizing the dynamic mechanism research of the interaction between urban-rural dual system both home and abroad, the article introduces non-linear dynamic model of urban-rural coupling region's system according to modem scientific theories, and extracts coupling degree index so as to reflect the evolution of the whole system and the level of coordination between the urban dominant correlative system and the rural one. Taking Nanjing city as an example, the method of principal component analysis is used to pick up four components among 28 indexes (namely, economic development, social coordination degree, resource allocation rate, and the negative environmental feedback mechanism) that could be undertaken demonstration analysis in terms of coupling degree, and to get the knowledge of evolution discipline in terms ofNanjing's urban-mral coupling region's system. This paper provids theoretical foundation for scientific planning and managing the region in term of how to recognize the coupling discipline of the urban-rural coupling regions system, how to find out the dominant factors and its functions of the urban-rural coupling region system evolution, and how to choose the new regional development patterns and coordinate new relationship between the urban and the rural system. Due to the urgent need of land and other basic infrastructures for central city's further development, Nanjing's urban-rural coupling region expands rapidly and inevitably becomes impediment to cooperative development between the urban and the rural. Under the circumstance that the urban and rural areas are highly coupled, the pressing task is to hold the whole system and its evolution trend related to the main associated system both the urban and the rural. The relationship of the above mentioned systems and the state of the whole system should be defined so that the whole system could be evaluated. Consequently, the proper measures for development can be adopted and the evolution speed of the main associated s
