吉林省城镇体系空间分布特征及其变化

Spatial Distribution Characteristics and Changes of Urban System in Jilin Province

本文分析了吉林省城镇体系空间结构的现状特点,1985年到至今的城镇人口、数量、城镇化等变化,以及通过对吉林省城镇网密度、理想随机分布平均距离、信息熵等的研究分析,可以得出吉林省城镇体系空间分布特征及其变化的相关内容:吉林省城镇数量、城镇规模、城镇化水平均处于较低水平阶段;吉林省城镇密度从1985年到至今的变化趋势小于全国的变化趋势;吉林省城镇空间发展不平衡,地域结构不协调;吉林省在30年期间的城镇空间分布向均匀发展。对吉林省城镇体系的发展提供相关建议。在现实意义上,也可为长吉图开发开放先导区城镇体系空间协调发展提供实践路径依据;为吉林省城镇体系规划提供客观、科学依据。

This paper has analyzed the present status and characteristics of the spatial structure of urban sys-tem in Jilin Province, since the urban population, quantity, urbanization change in 1985, and the study of Jilin Province towns’ density, ideal average distance of random distribution, information entropy analysis. We could come to the relative contents about Jilin Province urban system spatial distribution characteristics and variation: the number of cities and towns, the size of the towns, the level of urbanization were in a relatively low level stage;urban density in Jilin Province from 1985 since the trend is less than the trend in China;urban spatial development is not balanced, and the regional structure also lacks of coordination;during 30 years, its urban spatial distribution will in uniform development. We will also make some suggestions on the development of the urban system in Jilin province. On the practical significance, it will also provide basis path practice for Changjitu plans to open and develop pilot area of urban system spatial coordinated development, for the plan-ning of cities and towns in Jilin Province to provide objective and scientific basis.
