1990年以来江苏省县域城镇化测度及空间格局演化

Measure of County Urbanization and Spatial Framework Evolution in Jiangsu since 1990

基于熵值法从城镇人口、经济、空间和社会方面测度20世纪90年以来江苏省县域城镇化水平,运用ESDA空间测度模型对江苏省县域城镇化空间格局演化特征进行了研究。结果表明:1990年以来县域城镇化水平差异显著,但南北差异分布格局基本保持稳定;县域尺度城镇化表现出较强的空间自相关性特征,城镇化相似县域单元在空间上呈聚集分布态势,并且空间集聚的程度总体不断增强;县域城镇化热点区空间结构主要以苏州—无锡为核心的圈层结构,并且不断向宁镇扬地区演化。

With entropy method to evaluate county urbanization in Jiangsu from urban population, economy, space and society since 1990, and ESDA space measurement model to research the features of the spatial framework evolution, the study shows that the difference of urbanization is obvious, but the distribution patterns of north and south remain stable; the county urbanization is characterized with spatial autocorrelation; counties of similar urbanization is an aggregated distribution in space, the degree increasing; the hot areas of county urbanization is mainly the layer structure which increasingly develops to Nanjing, Zhenjiang and Yangzhou. of space aggregation is totally with the core of Suzhou-Wuxi,
