The Analysis of Changsha Spatial Self-organizing Mechanism in the Period of Republic of China

摘要

As an inland city, the spatial form of Changsha has undergone its development for more than two thousand years. Extremely stable development of socio-economical culture made little influence on the form evolution of urban center in Feudal Age. However, from 1904 to 1949, frequent and obvious changes on city's space configuration appeared along with the socio-economical revolution by reason of opening the port, and the characteristic of spatial replacement of downtown was also especially obvious. Therefore, changes of spatial configuration, as a reflection of free commercial economy after opening port, were studied in this paper to illustrator the self-organizing process of the city space evolution. With respect of studying method, space syntax theory was used to analyze and model the process of spatial organization rather than only using thus history or humanities perspective. After comparing syntactic measurement with five historical periods, the spatial features of self-organizing morphology present three rules: (a) self-similarity of morphological evolution, (b) synergy and disturbance relations by local-global spatial interaction and (c) city business center consistently located in the high integrated spaces. As a result, these rules of spatial self-organizing could be explained by a socio-physical phenomenon of single center configuration with today's city expansion.
