云南省城市规模分布演变及其空间特征
Evolution and Spatial Characteristics of City Size Distribution in Yunnan Province
【摘要】 本文采用云南省2003年—2012年的城市人口数据对云南省城市规模分布进行分析。运用城市首位度、位序—规模法则、城市基尼系数和区位熵等方法进行实证分析。结果表明,城市规模分布不均衡,城市间差距大,昆明市首位较高;2012年云南省城市规模分布不符合理想的人口位序—规模分布,大部分城市偏离直线区,形成大量的空白区域;人口基尼系数和基尼系数发展方向南辕北辙,经济水平越高,人口越集聚;经济发展与城市人口反映的区位熵,具有波动性;东部地区城市化水平总体高于西部地区。在此基础上提出"创新、生态、高效"城市发展策略。
【Abstract】 This paper collected the data of urban population from 2003 to 2012 in Yunnan province, analyzed city scale distribution in Yunnan province, adopted city primacy index, city population pyramid, rank-size rule, city Gini coefficient and location entropy to analyze the rule of the city scale distribution evolution. The result showed that,1.city scale distribution was not balanced, and there was the big difference p between cities; 2.in 2012, the population of city scale distribution did not conform to the ideal sequence-size distribution;3.population of Gini coefficient and economic Gini coefficient showed the different trend of development; 4. location entropy was volatile; 5.level of urbanization in the eastern were higher than the western. Based on these, advance city development strategies of innovation, ecology,and high efficiency.
【Key words】 city size distribution; city primacy index; rank-size rule; city Gini coefficient; location entropy; Yunnan Provinc;
