分析我国城市轨道交通系统发展及其类别， 结合城市对轨道交通的需求，提出运量和速度两个维 度的城市轨道交通需求矩阵; 针对城市轨道交通的特 征及适应性，从满足城市交通功能角度出发，提出我国 城市轨道交通系统的发展方向及建议，期望能为我国 城市轨道交通技术发展提供理论指导。

The paper analyzed the development and categories of urban rail transit systems. Considering the urban demand for rail transport, a two dimensional matrix of urban rail traffic demand was proposed, the main parameters of the matrix being transport volume and speed.To meet the demand of urban transport functions and in view of the characteristics and adaptability of urban rail transit systems, development orientation and proposals for China’s urban rail transit systems were put forward, which will serve as theoretical guidance to China’s urban rail transit technology
