摘要
交通可达性与经济发展水平的关系是交通地理学持续关注的重要议题。以县域单元为研究对象,结合地理空间分析技术和数理统计方法,探究贵州交通可达性与经济发展水平的特征及其空间格局。研究结果表明:①县域交通可达时间表现出可达性优的县占比多与可达性差的县占比少的等级差异现象,可达性强弱与城市人口规模呈现线性不匹配特征,呈现经济发展水平高的县域占比少与经济发展水平低的县域占比多的相对差异较大的“跷跷板”效应;②县域可达时间表现出强烈的空间差异且呈现以贵阳为核心向边缘逐渐递减的圈层式空间分布格局,可达性潜力呈现以贵阳都市圈和遵义中心城区为核心的区域强与以铜仁市、黔南州东部、黔东南州东南部、黔西南州西南部、六盘水市和安顺市南部组成的区域弱的“马太效应”现象,经济发展核心区与经济发展水平洼地连片带表现出强烈的空间不均等性且经济发展水平相对差距较大;③以贵阳都市圈和遵义中心城区及周边地区组成的区域是贵州县域可达性最优地区、县域可达性潜力最优地区和经济发展核心区。因此,未来应重点发展具有可达区位优势、潜力优势和经济基础优势的以贵阳都市圈和遵义中心城区及周边县域组成的经济发展核心区,扩大对黔中城市群的经济辐射,提升贵州县域经济发展整体水平。
The relationship between traffic accessibility and economic development level is an important topic in the field of transport geography.Taking the counties in Guizhou Province as the research objects,we used the methods of geospatial analysis and mathematical statistics to explore the characteristics and spatial pattern of traffic accessibility and economic development level at county level.It is concluded that:①county traffic accessibility time shows grade difference,with the counties with better accessibility more than the counties with poorer accessibility;there is a linear mismatch between accessibility and urban population size;the economic development level shows a seesaw effect,with the counties with high-level economic development less than the counties with low-level economic development;②county accessibility shows strong spatial differences,with a gradually decreasing distribution pattern with Guiyang at the core;the accessibility potential presents the“Matthew effect”,which is strong around the metropolitan areas of Guiyang and Zunyi,and weak in Tongren,Eastern Qiannan,Southeastern Qiandongnan,Southwestern Qianxinan,Liupanshui and South Anshun;there is a strong spatial inequality between the core area of economic development and the depressions of economic development,and the gap of economic development between them is relatively large;③the metropolitan areas of Guiyang and Zunyi have the highest county-level accessibility and accessibility potential,and are the core zone of economic development.Therefore,the metropolitan areas of Guiyang and Zunyi should be the focus of development,so as to expand the economic radiation to the urban agglomeration in Central Guizhou,and to enhance the overall development level of county economy in Guizhou.
