基于地理空间视角的湖南湘江新区辐射带动作用分析

An Analysis of Radiation Effect of Hunan Xiangjiang New Area Based on the Perspective of Geographic Space

作为中部首个国家级新区,湖南湘江新区的增长极正处于快速发展与集聚过程中,其发展与建设对引领和带动中部地区经济发展具有重要的战略意义。基于地理空间视角,应用层次分析法(AHP)、断裂点模型等方法,分析了湘江新区的辐射带动作用。研究结果显示:湘江新区对周边的辐射力影响暂时未能突破省界,在影响新区城市辐射力的各种要素中,诸要素的辐射力基本处于同一水平。

As the first national-level new district in central China,the development and construction of Hunan Xiangjiang New District has important strategic significance for leading and driving the economic development of the central region.Xiangjiang New Area is the research area.Based on the spatial analysis and visual expression technology of geographic information technology,the breaking point model is selected to construct the radiation analysis index system of the new area from the aspects of economic integration,industry,in⁃frastructure,resources,and culture.The analysis of the new area’s radiating and driving effect on the surrounding area from the per⁃spective of this can provide a powerful reference for the future planning and construction of the Xiangjiang New Area in Hunan.
