中文摘要：

基于现状城市形态分形研究与道路交通网络分形研究之闻缺乏相互渗透，而城市土地利用与交通网络发展又是一个互动协调的发展演化过程，两者形成L-T超循环系统，本文提出城市形态分维与道路交通网络分雏相匹配一致的演化结论，并建立协调因子概念及计算模型评价两者之间的协调度，最后结合成都市历年城市用地形态与城市道路网络发展演化对两者之间的互动协调演化关系进行了实证分析，所得结论较好地解释了现实状况．

英文摘要：

The interrelation of urban morphology fraetal and road network fraetal is seldom studied, but beth have influence on each other and form a L-T hypercycle system. The consistent evolution between urban morphology dimension and road network dimension are proposed and the coordinate gene conception and model put forward for evaluating the matching relationship between them. Finally Chengdu city was taken as an example to analyse its the evolution process of urban morphology and road network. The actual status is well explained by obtained conclusions.
