连片特困区交通优势度评价及其与贫困关系研究——以武陵山片区及其周边四省为例

Assessment on Transport Superiority and Relation with Poverty in Contiguous Poor Areas——A Case Study of Wuling Mountain Area and Its Surrounding Four Provinces

构建交通优势度评价模型,对武陵山片区周边四省共307个县级单元进行评价,并与反映县域贫困的重要指标之一的人均GDP进行耦合。结果表明:交通优势度与交通—经济耦合协调度在整体范围上呈明显的中心—外围分布,在片区内呈东高西低的格局,且存在较强的空间集聚效应。交通优势度与贫困水平呈显著正向相关关系,交通是区域贫困的重要原因。黔江区和怀化市可规划为交通枢纽中心,黔江、怀化、张家界和铜仁市区可作为中心城市进行规划。

This paper built the transport superiority evaluation model to calculate the transport superiority of total 307 county unit in Wuling Mountain Area and its surrounding four provinces, then used county per capita GDP for coupling. The results indicated that：Transport superiority and trafficeconomic coupling coordination degrees had similar distribution. In large range, it was obviously of centerperimeter distribution in Wuling Mountain Area. It was east high west low pattern, and space concentration was high. There was a significant positive correlation between transport su- periority and poverty. Transport became an important factor in economic development. Huaihua and Qianjiang could be treated as transportation hub. Qianjiang, Huaihua, Zhangjiajie, Tongren could be planned as center city.
