摘要: Rapid urbanization in China has induced profound changes in the relationship between urban and rural areas, especially in urban agglomerations. This paper contributes a better understanding of the mechanisms of urban rural interactions in urban agglomerations by considering the perspective of the spatial organization of urban rural integration (SOURI). Using the Chang-Zhu-Tan Urban Agglomeration in Central China as an example, this study used a spatial autocorrelation analysis to quantify the agglomeration and diffusion patterns of the population and firms as proxies to reveal the spatial organization pattern of urban-rural integration (SOPURI). The results showed that 1) the spatial proximity and centralization trends of SOURI were obvious in 2005-2015 in this region; 2) the urban districts of prefecture-level cities, especially Changsha, played an important role as the main centres; 3) due to diffusion effects from the central urban districts, a few county-level cities and county towns began to appear as sub-centres; and 4) the function of towns needed enhancement. Furthermore, a model of an urban-rural multi-level polycentric network was proposed to guide the optimization of SOURI in urban agglomerations with an emphasis on the three-level centres of city-town-village and networking linkages. Following the model, optimization policies for the Chang-Zhu-Tan Urban Agglomeration are discussed.
