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
【摘要】 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。
