城镇体系是在一定地域范围内,由一组规模不等,性质、形态各异,彼此间存在着相对稳定的分工协作关系,并具有一定结构和功能的城镇群。这组城镇群具有关联性、层次性、开放性和动态性的特征。其内涵主要包括城镇的职能结构、规模等级结构和地域结构。城镇体系是区域经济集聚的结点、交换的中心、流通的枢纽,在区域经济发展中起着先导和核心的作用。城镇体系的形成和发展是一个从小到大,从低级到高级的历史过程。它与交通运输的发展互为条件,互为因果,但在建设程序卜,交通运输业应处于超前地位。本文拟结合首都地区的实际,探讨二者关系,以及如何改善交通状况以适应城镇体系发展的需要。这里的“首都地区”是指北京、天津、唐山、秦皇岛、承德、张家口、保定、廊坊、沧州等12个地、市,方圆16.8万平方公里的区域。
In a certain area, the urban system consists of a group of urban agglomerations with different scales, different types and different forms, and a relatively stable division of labor and cooperation with each other and with certain structures and functions. This group of urban agglomerations has the characteristics of relevance, hierarchy, openness and dynamism. Its connotation mainly includes the functional structure of cities and towns, the scale of structure and the regional structure. The urban system is the node of regional economic agglomeration, the center of exchange and the hub of circulation, playing a leading and central role in the development of regional economy. The formation and development of a town system is a historical process ranging from small to large and from low to high. It is mutually dependent on the development of transportation and is mutually dependent. However, in the construction process, the transportation industry should be in a leading position. This article intends to combine the reality of the capital area to explore the relationship between the two, and how to improve the traffic conditions to meet the needs of the development of urban system. The “capital area” here refers to a total area of 168,000 square kilometers in 12 cities including Beijing, Tianjin, Tangshan, Qinhuangdao, Chengde, Zhangjiakou, Baoding, Langfang and Cangzhou.
