摘要
以基尼系数为基础,引用国际上应用较多的或在此基础上设计新的"极化指数模型",用以测定不同时段东北地区城镇系统的空间极化程度的变化。应用辽宁省、吉林省、黑龙江省统计年鉴,县级市、地级市市区统计资料和中国城市统计年鉴,采集4个年份各市、县的指标进行分析。指标的选取力求全面反映地区的综合发展水平以及时间、空间上的可比性。2000年以前,县级单元间还处于较为均衡的状态,2000年以后,空间极化现象开始有所显现,2003年基尼系数达到了0.309。"沃尔夫森指数"和"崔一王指数"也表现了同样的变化趋势,2003年分别达到了0.285、0.631。极化现象正在县级单元逐步变的明显。
Based on geordie coefficient, we measure the diversification of the urban system spatial polarization degree of Northeast China in different period by referring the model of polarized index which is used widely abroad or designing a new on the base of tiffs. The indexes of cities and counties in four yea＇s were analyzed using the statistical yearbooks of Liaoning Province, Jilin Province and Heilongjiang Province, the statistical data of each county, county - level cities and prefecture - level cities and the urban statistical yearbook of China. The choose of indexes try to reflect regional comprehensive development level and comparability on temporal and spatial scales. Cells of county were in the state of more equilibrium before 2000, but the phenomenon of spatial polarization has appeared after that, and the Geordie Coefficient reaches 0. 309 in 2003. Wolfson index and Tusi - Wang index are also showed the same diversification trend, reached 0.285 and 0.631 respectively in 2003. The polarization had been obvious gradually in the cell of county.
