摘要
本文采用城市人居环境的综合得分作为测算对象,选择1987~2005年的数据对环渤海19个代表性城市的人居环境建设水平首次进行城市首位度、位序—规模法则、分形理论的分析计算,定量阐释了研究区域城市人居环境建设的均衡程度及其时空演变趋势。结果表明:(1)随着时间的发展,研究区域内城市间人居环境建设水平的均衡性不断增强,整体水平也在不断提高;(2)环渤海地区城市首位分布不明显,首位城市的垄断力在不断下降;(3)城市人居环境综合得分的空间分布由"单核心"向"三核心"转变,到2005年基本形成北京、大连、青岛的三角格局;(4)根据城市人居环境位序—规模曲线形状的变化,将环渤海所选城市划分成三类:人居环境较好型、人居环境一般型、人居环境较差型。
Taking the synthesized scores of urban human settlements as the measurable target, and Selected the data from 1987 to 2005, the paper analyzed the quality of urban human settlements with urban primacy index, rank-size rule and fractal theory among nineteen cities in Bohai-rim for the first time. It also illustrated the balanced level of urban human settlements and its space-time evolution quantitatively. The result shows that: firstly, with the time going, the level of human settlements among different cities tended to be balanced and also we can see the overall level was increasing gradually. Secondly, the urban primacy distribution in Bohai-rim agglomeration was not obvious and with the time going the primacy city's monopoly power declined gradually. Thirdly, the spatial distribution of urban human settlements transferred from the 'single-core' to the 'three-core', and to 2005, Beijing, Dalian and Qingdao has been the 'triangular structure'of the region. At last, according to the curve shape, we claimed that the selected cities of Bohai-rim could be divided into three categories: better living environment, general living environment and poor living environment.
