湖南省市镇规模等级结构的动态研究

本文应用市镇人口规模分布理论,研究了湖南省城市人口规模分布结构的动态变化及其基本特征。同时构造了2000年湖南省市镇序秩--规模分布模型,并利用logistic函数对预测结果进行了验证。预测表明:2000年南省市镇人口、市镇化水平分别约为2174万和32%,特大城市和大城市将扩大为长沙、衡阳、湘潭、株洲、岳阳和常德六市。据此对2000年湖南省市镇等级体系进行了规划。

ON THE HIERARCHICAL STRUCTURE OF URBAN SYSTEM IN HUNAN PROVINCE

The authors explore the rank-size relationship in Hunan Province and find out that this region exhibits a city-size distribution which approximates to the rank-size rule. Using the rank-size model, changes in city-size distribution over the period (1960-1990) are generally examined.
A modification of the rank-size model was used to analyze the structure of the urban system in this province in 2000. By the year of 2000, it would have its urban population of about 21.74 million and its urbanization of about 32 percent, which is attested by using the logistic function.
according to this analysis, three groups of cities were distinguished:
(1) those cities the urban population is over 500000, including Changsha、Hengyang、Xiangtan、Zhuzhou、Yueyang and Changde.(2) those cities the urban population is from 200000 to 500000, including Shaoyang、 Chenzhou、Yiyang、Lengshuijiang、Loudi、yongzhou (Lengshuitan)、Sinli、Huaihua、Liling、Dayong、Jishou.
