摘　　要：为探寻多中心组团城市粘连式扩展对城市交通的影响机理,建立了模型模拟组团城市粘连式空间扩展过程,并运用时空消耗理论测度一定城市功能布局下,组团扩展各阶段的交通时空消耗,结果显示:组团粘连阶段城市交通时空消耗需求最大。通过对重庆市组团粘连区人和、礼嘉、悦来地区的交通特征进行实地调查,发现粘连区跨组团出行比例,小汽车出行比例均明显高于全市平均水平;交通时空消耗计算结果显示该区域交通时空消耗是重庆市主城区平均水平的1.5倍,证明组团粘连式扩张削弱了组团城市的交通效率。The aim of the paper is to explore the influence mechanism of group adhesion on the urban traffic of polycentric group city.The model is used to simulate the urban spatial expansion process,and the theory of spatiotemporal consumption is used to measure the traffic space and space consumption of each under certain layout of urban function.The results show that the demand of urban traffic spatiotemporal is the largest in the stage of residential group adhesion.Through the field investigation of the traffic characteristics of the people in Renhe,Lijia,Yuelai-the adhesion region of Chongqing urban area,it was found that the proportion of the cross-group travel ratio and the proportion of car travel were significantly higher than the average level.The calculation resultsof traffic spatiotemporal consumption show that the traffic spatiotemporal consumption in this region is 1.5 times of the average level of Chongqing urban area,weakening the traffic advantage of the group city.It is proved that the residential group adhesions expansion weakened the traffic efficiency of the group city.
