从可持续发展角度提出了当前我国城市轨道交通发展过程中面临的几个技术问题,提出规划线网规模、系统规模要预留发展空间,制式选择要与功能定位和环境相适宜、建设标准需要适当提高,同时提出了信息化、全自动驾驶以及BIM(建筑信息模型)等新技术的应用要紧密结合建设和运营需求,并要与我国经济社会发展阶段相适应.%In this paper, some technical problems for the de-velopment of urban rail transit in current China are raised from the perspective of sustainable development,including the plan-ning scale of rail transit network,the reserved space for system scale development,the suitable system selection for functional positioning and environment,as well as the higher standards for construction. At the same time,in rail transit construction and operation,the application of new technologies like infor-mation technology,full automatic driving technology and BIM (building information modeling)technology are proposed,in order to meet the requirements of current economic and social development stage in China.
