摘　　要：通过提出城市群交通与经济发展水平之间的评价体系,对交通可达性与经济联系格局两者的耦合协调关系进行分析;结合城市群行政划分的特点,使用改进的加权平均出行时间平均值更加准确地描述了区县级交通系统水平。将该体系应用到长株潭城市群交通和经济发展水平协调分析研究中,结果表明:①长株潭城市群公路网可达性受地形影响,整体上呈现“一大两小”的核心—边缘空间分布格局;②长株潭城市群经济联系空间分布格局与路网可达性空间分布格局有一定的关联,但两系统的空间自相关程度并不完全一致,其中交通系统对两系统协调发展水平的空间格局形成影响更为显著;③长株潭城市群区县的交通与经济耦合协调发展水平整体不高,处于中低度协调阶段。This paper proposes an evaluation system between urban agglomeration traffic and economic development level,and analyzes the coupling and coordination between traffic accessibility and the economic development.Combined with the characteristics of urban agglomeration administrative division,this paper uses the modified average of weighted average travel time to achieve a more accurate description of the traffic system.Applying the evaluation system to the coordinated analysis of the transportation and economic development level of the Changsha-Zhuzhou-Xiangtan urban agglomeration,the following conclusions can be drawn:①the accessibility of road network in Changsha-Zhuzhou-Xiangtan Urban Agglomeration is affected by terrain,and it presents the core edge spatial distribution pattern of"one big and two small";②the spatial distribution pattern of economic that ties up Changsha-Zhuzhou-Xiangtan urban agglomeration has certain relevance with the spatial distribution pattern of road network accessibility,but the spatial autocorrelation degree of the two systems is not completely consistent,and the traffic system has more significant influence on the formation of the spatial pattern of the coordinated development level of the two systems;③the coordinated development of transportation and economy of Changsha-Zhuzhou-Xiangtan urban agglomeration is in the middle and lower levels.
