根据城市化的内涵及推进城市化的目的,从人口城市化、经济城市化、居民生活城市化、景观环境城市化和基础设施城市化等五个方面,构建区域城市化质量的综合评价指标体系,运用熵值法,对2001-2009年江苏县市城市化质量进行综合测度,并以此为变量,运用差异系数,对江苏县市城市化质量差异的演变过程与空间格局进行定量分析。结果发现:2001-2009年江苏区域城市化质量差异总体扩大的基础上呈现先扩大后缩小趋势,且主要表现为经济发展质量差异、基础设施质量差异和居民生活质量差异,人口发展质量差异和景观环境质量差异则相对较小;在空间上,县市城市化质量提升有向环太湖地区不断极化的态势。其中,地级市区以向下收敛为主;苏中和苏北县域以向上收敛为主,而沿海地区县域以向下发散为主;苏南地区的沿江县域以向下收敛为主,环太湖县域则以向上发散为主。

According to the meaning of urbanization and the aim of promoting urbanization, from population urbanization, economic urbanization, residential living urbanization, landscape environment urbanization and infrastructure urbanization, we build the evaluative indices system of regional urbanization quality and use entropy method to estimate the urbanization quality of the counties and cities of Jiangsu Province from 2001 to 2009. And then taking these as variables, we also use coefficient of variation to analyze the process and pattern of urbanization quality of the counties and cities of Jiangsu Province. The results are as follows: firstly, since the beginning of the new century, the differences of regional urbanization quality in Jiangsu Province have shown the trend of expansion; secondly, the urbanization quality of cities and counties in Jiangsu Province improves gradually, but their spatial polarization becomes increasingly obvious at the same time. Prefecture-level city downtown areas give priority to downward convergence, central and northern Jiangsu counties give priority to upward convergence; Lastly we should accelerate counties economic development of the northern and central areas in Jiangsu Province (especially in coastal areas), constantly improve their infrastructure construction and people's living standards, establish the regional cooperation organization which is promoted by the government in order to break through the region as a unified regional economic system. With those measures have been finished can we accelerate the upgrading of the urbanization quality development in Jiangsu Province, narrow the disparities in regional development and promote the strategic transformation of urban development initiatives.
