Abstract:

On the basis of the research results in recent years, the paper puts forward the studying route, i.e., introducing inductance and influence indexes, proposing the used parameters to measure contact, confirming the main and subordinate contact directions based on the hierarchies of and forming the spatial structure of urban agglomerations (UAs). According to the hierarchies of exponents, the paper indicates that Industry Contact Intensity (ICI) is different in different urban agglomerations; the degree of difference depends on the hierarchies of urban agglomerations and the spatial collocating relationship of each city. The greater the hierarchies, the greater degrees the difference has. Basing on the distribution of main and subordinate contact directions, the paper partitions four types of the structures, such as network-denseness, spatial-decentralization, core-centered and core-deflective patterns. In addition, this paper abstracts different exterior-configurations basing on the shapes when the width of lines representing industry contact intensity changes from 0.2 to 18. Meanwhile, it puts forward the system of space exploiture on different ranges, such as the whole country, urban agglomeration systems and individual ones, macroscopical direction and emphases in different urban agglomerations, and summarizes blueprints of spatial development in different stages for every urban agglomeration. Finally, the paper summarizes the theoretical meanings of this study and put forward the direction of research in this field.
