摘　　要：选取皖江城市带2002—2008年公路里程、公路客运量和公路货运量及人口、面积、经济等数据,通过年增长率、变化比例、公路密度、区位商等比较,对皖江城市带的公路时空变化进行研究。从总体上看,皖江城市带的道路等级体系较低,仍以四级公路和等外公路为主。从时间变化上看,总体呈上升趋势,2005年后发展更快。从空间变化上看,沿江的东西方向和合巢芜—芜宣高速沿线的南北方向是皖江城市带内公路客运量和货运量快速发展的重要地带。最后,从自然条件、经济和人口因素、投资与政策方面对皖江城市带公路网变化成因进行分析。Selected the historical data of total length of highway,road passenger traffic,road freight traffic and population,area,economic data in Wanjiang city belt from 2002 to 2008.This paper studied the temporal and spatial evolution of road network in Wanjiang city belt by comparing the annual growth rate,change ratio,highway density,location quotient,etc.On the whole,the road hierarchy in Wanjiang city belt is low and still mainly of class Ⅳ and highway below class Ⅳ.From the time-varying point of view,the total trend is lifting,and it growth faster after 2005.The cities along the Yangtze River and He-Chao-Wu and Wu-Xuan expressway are the important areas in the growth of road passenger traffic and road freight traffic.Finally,this paper analyzed the factors cause the changes of road network in Wanjiang city belt from natural conditions,economy,population,investment and policy.
