摘要
交通区位条件是反映区域发展潜力的重要指标,分析其与空间开发强度之间的时空协同关系对揭示区域发展的动力机制具有重要启示意义。以重庆市为例,通过指数建模、回归拟合及弹性系数等方法,揭示其间互动关系。研究发现:(1)研究区交通区位指数处于快速跃升阶段,区域差距有所缩小,空间集聚格局基本稳定;(2)空间开发强度指数数值整体偏低,增速差异较大,空间集聚格局呈单集聚中心向多集聚中心演进趋势;(3)不同类型的交通区位指数(内部、外部和综合)与空间开发强度指数均呈显著正相关,且关联性表现出不同状态;(4)交通区位演化与空间开发强度互动敏感程度较高,各弹性系数空间集聚格局基本一致,但其形成机理差异较大。
Transportation location condition is an important index reflecting regional social and economic development status and development potential.Taking Chongqing as an example,this paper chooses two time sections in 2005 and 2015 to reveal the interaction between traffic location evolution and spatial development intensity by means of index modeling,regression fitting and elasticity coefficient.The study finds:1)The traffic location index of the study area is in a rapid jump stage.2)The spatial agglomeration characteristics of traffic location index are obvious and the dispersion is reduced.3)Different types of traffic location index(internal traffic index,external traffic index and comprehensive traffic index)have significant positive correlation with spatial development intensity index,and the correlation shows different states.4)The evolution of traffic location is closely related to the change of spatial development intensity,and the interaction between them is more sensitive.
