论城市用地和交通的相互关系

城市是一个复杂的社会经济系统,人们在城市系统中从事各种活动。在城市活动与其用地和出行需求之间,存在着极其复杂的相互关系。认识这种关系并利用其中的规律来进行科学合理的城市用地和交通规划,是城市规划和城市交通学科的基础研究课题之一。从分析城市活动入手,揭示了城市活动是用地和出行的需求之源,进而阐述了城市活动的两个基本供应子系统——用地和交通之间的相互关系。指出重视用地和交通的交互作用,寻求城市活动与其用地和交通之间的供求平衡,既是维持城市健康发展,也是指导城市用地和交通规划的基本原则。

Comments on Interrelations between Urban Land-Use and Transportation

A city can be thought of as a social and economical system with significant complexity, and with various activities taking place within the system. Between the activities (as the demand side) and the land-use/transportation (as the supply side), there exist extremely sophisticated interrelations. A better understanding of these interrelations for utilizing the underlying mechanism to develop urban land-use and transportation systems in a scientific and reasonable way is one of the basic research subjects in both urban planning and transportation fields. Starting with an analysis of activities, this paper reveals that activities are the demand source of land-use and transportation, and then discusses the interrelations between the two supply subsystems, i.e. land-use and transportation. The paper further points out that emphasizing on interactions between land-use and transportation in achieving equilibrium in demand and supply between activities and land-use/transportation is the fundamental principle not only for a healthy and sustainable urban development, but for a sound planning of urban land-use and transportation as well.
