将城乡道路网系统解构为需求、供给两个子系统,构建系列评价指标体系和引入耦合协调度模型,从地市、县市层面揭示了1995—2012年武汉城市圈城乡道路网供需系统的时空协同演化格局:地市层面上,武汉城市圈城乡道路网供给系统呈现出“核心—边缘”的空间生长趋势,需求系统呈武汉“一城独大”格局。城乡道路网供需系统耦合度由低水平向高水平发展,空间差异较小,协调度由失调向良好协调发展,呈现出同步进阶的态势;县市层面上,供给系统县际差异趋小,呈现等级圈层式的空间发育格局,需求系统也发展较均衡,呈板块集聚特征。城乡道路网供需系统耦合协调度整体水平不高,“核心—边缘”格局显著。
Deconstruction of urban and rural road network system as the demand, supply two subsystems, build a series of evaluation index system and the introduction of coupling coordination model, and reveal the spatiotemporal coordination of urban and rural road network supply and demand system in Wuhan city circle from 1995 to 2012 Evolution pattern: At the municipal level, the urban and rural road network supply system of Wuhan urban agglomeration shows a spatial growth trend of “core-periphery ”. The demand system is Wuhan “one city is the largest ” pattern. The coupling degree of supply and demand system of urban and rural road network developed from low level to high level, the spatial difference was small, and the coordination coordinated from disorder to well coordinated, showing the trend of simultaneous advancement. At the county level, Showing the level of the spatial pattern of the formation of layers, the demand system also developed a more balanced plate was gathered features. Urban and rural road network supply and demand system coupling coordination overall level is not high, “core - edge ” pattern is remarkable.
