Urbanization Quality Zoning Research of Economically Developed City Based on Catastrophe Theory——A Case of 13 Prefecture-Level Cities of Jiangsu Province
以江苏省13个地级市为对象，用突变级数法和聚类分析建立城镇化质量分区框架，发现质量呈明显空间分异，可划分为四个等级，并分析形成机制提出对策。
This paper select 13 prefecture-level cities of Jiangsu Province,a developed province located in Yangtze River Delta,as the study area based on catastrophe theory,using catastrophe progression method combined with cluster analysis methods to establish the theoretical framework of urbanization quality partition and to evaluate the urbanization quality of the study areas,we can draw that the pattern of urbanization quality of cities in Jiangsu Province has obvious spatial differentiation phenomenon. Meanwhile,according to the characteristics of each urbanization city in Jiangsu Province,we can divide it into four quality levels of urbanization zone. Then we deeply analysis the formation mechanism of various grades to identify the characteristics of each district,and find to how to adjust rationally the path of urbanization,put forward the corresponding countermeasures. The paper also confirms that the quality of catastrophe theory has some applicability in urbanization partition.
