本文对国内外绿色轨道交通工程的建设及运营现状进行了调研，提出了绿色轨道交通工程的概念，对其特征表现进行了较为系统的梳理。从规划设计、施工、运营维护及管理等对城市轨道交通的绿色技术进行了详细剖析，最后从技术集成、科技创新、装备研发及评价体系构建等方面对绿色轨道交通的发展方向进行了阐述，以期为绿色轨道交通工程的建设和运营维护提供借鉴和参考。

Research on construction and current operation situation of green rail transit engineering were conducted firstly. Then, the concept of green rail transit engineering was put forward and its manifestation was combed systematically. The green technology of green rail transit engineering was analyzed in detail from four aspects: green planning and design, green construction, green operation and maintenance, and green management. Finally, the direction of green rail transit development was elaborated from aspects of technology integration, technical innovation, equipment research and development, establishment of assessment system etc. to provide reference for construction, operation and maintenance of similar engineering.
