Spatio-Temporal Evolution of Urban Size System and Its Spatial System in Jiangxi Province since 2000
摘要
Abstract
Urban size structure is one of the three major structures in urban system. Rational analysis on regional urban size structure would be of help to understanding the phase of urban system, and has significance on forcasting cities’ population and planning the structure of urban system. Using the population data of each city and county in Jiangxi Province during the period from 2001 to 2012, with the aid of Arcgis and SPSS, this paper analyzed the features and evolution of the hierarchical structure of the urban system in Jiangxi Province based on the standard deviation index, coefficient of variation, city primacy index, city Gini coefficient and Fractal Theory. The following conclusions were made:1) Urbanization in Jiangxi Province developed rapidly during the period from 2001 to 2012, with the number of big and medium cities increasing, Jiangxi Province was changing its original irrational urban size system, in which the small cities were over-concentrated, and the pyramid of urban size tended to be reasonable;2) The relative disparity of city population had increased while absolute disparity decreased. The urban system’s size structure trended to be reasonable; 3) Urban primacy ratio of Jiangxi was relatively high and city distribution pattern in Jiangxi Province followed the Primate City Law typically, Nanchang was the primate city, whose agglomeration effect was obvious; 4) City scale fractal dimension was small and decreased significantly, meanwhile, big cities developed faster than small and medium-sized cities, those showed a significant Agglomerative Effectiveness; 5) The spatial evolution of urban size had the characteristics of regional difference, ring agglomeration and the axis with directivity were obvious. Finally the paper pointed out some problems about distribution of urban size, such as too little megacities, small urban scale and excessive north-south gap of urban population growth, and also put forward the corresponding countermeasures against those problems.关键词
