基于主体功能区划方法的长株潭城市群核心区交通优势度评价

Appraisal of Transport Superiority Degree in Changsha-Zhuzhou-Xiangtan Urban Group Based on Major Function Regionalization

基于主体功能区划分的原理,以乡镇为评价单元,运用Arc GIS空间分析方法,在对公路网密度、交通干线影响度和区位优势度各单因素评价的基础上,对长株潭城市群核心区各评价单元的交通优势度做出评价。结果表明:长株潭核心区交通优势度呈现长沙市区"一主核",株洲和湘潭"两次核",并向外圈层依次递减的格局,且交通优势度与区域经济呈正相关。

This article is based on the principle of major function regionalization, in the villages and towns as evaluation unit, evaluated transport superiority degree of each unit in Changsha-Zhuzhou-Xiangtan Urban Group by using ArcGIS spatial analysis method on basis of evaluation on highway density, effects of traffic trunk and Location advantage degree. The results showed that transport superiority degree presented Changsha ＂a main core＂, Zhuzhou and Xiangtan ＂two nuclear＂ and outward circle pattern in descending order, and the transportation and regional economic dominance correlated positively.
