Abstract: Under the guidance and support of relevant national and industrial policies, the green and lowcarbon of rail transit is an important development strategic direction of the industry. In order to response the strategy, the system research suitable for Xi′an green urban rail is carried out based on the pilot stations.  First，the selection of standard system is analyzed. Then,the whole process of multibody collaborative design method is put forward according to Xi′an urban rail transit construction management mode. Last,taking Shengliu Village Station of Xi′an Metro Line 10 as an example, the low carbon and energysaving technical route of building "green station" and the application of new technology are studied. The study lays a foundation for carrying out the systematic technology research on the green building (green and lowcarbon) of urban rail transit covering the planning, design, construction, and operation of the whole life cycle, the whole process, and all participants in the future Xi′an urban rail transit.

Key words: urban rail transit, green and lowcarbon; code standard, collaborative design, new technology of energy saving
