摘要
根据建设模式的不同,对我国城市轨道交通建设发展历程进行了阶段划分。就城市轨道交通的"线路"、"网络"和"体系"进行了理论分析与诠释。在对城市轨道交通线路式、网络化、体系化等三种建设模式解读和论述的基础上,提出体系化建设是我国城市轨道交通建设的发展趋势。
According to the different patterns of URT （urban rail transit） construction, its development process can be divided into three stages： the line construction, the network construction and the system construction, From the point of physical meaning and systematic functions, this paper gives a theoretical analysis of and an interpretation for the ＂line＂, ＂network＂, and ＂system＂ of URT, Base on the analysis and discussion of throe construction patterns, this paper points out that the system construction is becoming the trend of URT development in China, and further analyzes the key steps in the implementation of the system construction. The author also indicates the characteristics of the system construction of URT from aspects of systen：atic technology, resource utilization, construction management and construction conditions. Finally, this paper concludes that the system construction can fully embody the concept of ＂safe metro, efficient metro, scientific metro, green metro, human-oriented metro and workable metro＂, which can greatly enhance the quality of URT system in China.
