The Mechanism of the Model of Dual-nuclei Structure

LU Yu-qi (Department of Geography, Nanjing Normal University, Nanjing 210097, China)  
The model of dual-nuclei spatial structure is a kind of phenomena of spatial structure that is composed of a regional central city, a port city and their relations at a certain region It is generally founded in the coastal belt, the region along the Yangtze River in China and other countries and regions in the world. From the view of the mechanism, the phenomena of dual-nuclei spatial structure comes from spatial compag of a regional central city and a port city. Because giving attention to centered nature of a regional central city and fringe nature of a port city, it can carry out complements in station and function. From the view of type of formation, the dual-nuclei spatial structure can be classified into two types, namely, endogenic pattern and ectogenetic pattern. China and America are their typical deputies. From the latter, it derives the special phenomena of dual-nuclei spatial structure that is made up of the new capital and the old. The formation of dual-nuclei spatial structure has something to do with the drainage basin. According to it, we can build up an ideal model about the formation of dual-nuclei spatial structure that is based upon the drainage area. The integrated action which includes the natural condition character of drainage area, the change of transport structure and the direction of mostly transport route can make the forming area of dual-nuclei spatial structure spread from the drainage area to other common area.
