山地城镇体系规模结构的计量分析及分形特征研究——以滇西南临沧市为例

THE QUANTITATIVE ANALYSIS AND RESEARCH ON THE FRACTAL CHARACTERISTICS OF MOUNTAIN URBAN SYSTEM SIZE STRUCTURE——A CASE OF LINCANG IN SOUTHWEST OF YUNNAN PROVINCE

以滇西南地区临沧市2003～2008年各山地小城镇的人口规模数据为基础,运用城市地理学中的位序-规模法则、城市首位律及不平衡指数和自组织理论中的分形理论相结合的方法,对临沧市城镇体系规模等级结构进行定量和定性分析,从计量分析和分形研究两个方面对临沧市城镇体系规模等级结构特征进行总结,结果表明,临沧市城镇体系规模等级结构具有分形特征,处于低级平衡状态,发育还不成熟,但有开始走向成熟的趋势。最后根据临沧市城镇体系规模结构的特征提出相应发展建议。

According to the population data of mountain towns of Lincang in southwest of Yunnan Province from 2003 to 2008, this paper studied scale hierarchical structure of mountain urban system from quantitative and qualitative analysis using the rank-size law, the primacy law, the unbalance index in urban geography and fractal theory in self-organization theory. The scale hierarchical structure characteristics of urban system in Lincang was summed up from two aspects： measurement analysis and fractal study. The results show that scale hierarchical structure of mountain urban system developed immaturity but began to mature and it was in a low-level equilibrium. the fractal characteristic is obvious. Finally, the recommendations according to the above analysis are propored.
