城市聚落规模的分布特征探讨 ——以浙江省为例 邓丽君，韩昊英，吴宇哲 (浙江大学土地管理系，杭州 310029) 摘要：结合规模—位序分布、分形理论和等级钟三种理论方法，从不同的角度和层面分析了浙江省 1988-2007 年 各年城市聚落以统计年鉴非农人口表征的规模分布特征。研究结果显示，浙江省城市聚落在研究时间范围内呈规 模—位序分布，人口分布都比较均衡，中间位序城市聚落规模较相近，城市体系整体发育较成熟。总体分布在时 间上较稳定，分维值总体上随时间不断增大，保持在1.00-1.12 区间内。微观上不少城市出现了规模位序的上下浮 动，20 年间总的位序变动平均距离接近1，多方面的原因造成了这种变动。 关键词：城市地理；规模—位序分布；分形理论；等级钟 Study on Size Distribution Characteristics of Urban Settlements — A Case Study of Zhejiang Province DENG Lijun, HAN Haoying, WU Yuzhe （Department of Land Management, Zhejiang university, Hangzhou 310029, China ） Abstract: The paper analyzes the characteristics of scale distribution in Zhejiang province from 1988 to 2007, combing rank size distribution, fractal theory and rank clock for the first time, in which city scale is defined by non-agricultural population in statistical yearbooks. The results show that city settlements in Zhejiang Province exhibit phenomenon of rank-size distributions within the each year. Population distribution is tend to be balanced, the size of urban settlements in the middle rank are similar to each other, and the overall development of urban system is close to mature. Overall distribution is stable in time; the fractal dimension generally increases with time continuously, remaining in the 1.00-1.12 range. Many cities in the micro-scale display volatile rank, the total average distance change of rank in 20 years is close to 1, and this volatility is contributed by many reasons.
