江津市城镇体系结构研究

首先在城镇体系等级规模分布研究基础上，提出江津市仍处于城镇体系发育的极化阶段，确定中心城市仍是市域内未来的发展极；其次借助于地理信息系统软件测算镇镇间直线距离，在对城镇的空间分布研究的基础上，得出江津市城镇集中在两条地理线上，从而确定市域内未来发展轴，并用现状资料对此结果进行了验证，接着对市域内城镇体系的职能结构做出了定性的分析；最后依据江津市城镇体系存在的实际情况和发展趋势，提出了优化江津市城镇体系等级规模结构、空间结构、职能结构的途径及其发展思路。

A RESEARCH ON URBAN SYSTEM STRUCTURE IN JIANGJIN CITY

The authors considered that the growth of urban system structure in Jiangjin City is at polarizing stage,according to the urban system rank-size structure,and that the inner city would be the growth pole in future.Secondly,the distance between towns by using Arcgis 8.3 was measured out,and this paper suggested that the city would congregate in the two main traffic lines,which would form the development axis of the city in the future.Thirdly, the urban function structure was qualitatively analyzed.Finally,according to the present situation and future development of the urban system,some ideals in optimizing urban system structure and development routes were put forward,and then some referenced bases for the development of the city in the future were pointed out.
