中文摘要：
基于国内研究进展的评述。本文分析了我国高速公路网络的空间演化过程，认为以1997年为界存在缓慢发展和快速发展两个阶段．并探讨了高速公路网络的组织模式；作者深入考察了高速公路发展的区域效应．分析了高速公路对全国公路交通流格局的演化影响和高速公路建设对城镇密集区的公路交通流格局和地域系统的影响，并以省会城市为中心，探讨了高速公路对30分钟和1小时交通圈的空间效应。
英文摘要：
With the development of express ways, they has became the main transport model of road system, affecting the development of social-economy and urban region. In this paper, based on the research history and progress in China, the author analyzed the spatial evolution course of express way networks in China, which have the slowness development （1988-1997） and quick development stage （1997）, and discussed their spatial organization models, including regional access, urban circle road, access between hub cities, urban interior road, and travel road. Furthermore, by designing the shortest time model and O-D matrix, the author analyzed the regional impaction of express way networks in detail. Firstly the evolution of traffic flow structure in China was discussed, which enlarged the transport distance of road system and actuated the traffic to concentrate in the East region of China. Secondly, the author analyzed traffic flow structure of urban regions and its region system, which emerged as the main traffic flow access and hub-and-spoken system in Yangze delta and Pear river delta urban regions and Thirdly, the express transport circle of 30M and 1H around province cities were discussed and drew the conclusion that express way enhanced their service scope and accelerated concentrating speed of population and products to province cites.
