Low carbon transportation system saves resource, decreases carbon emission, realizes sustainable economic development,rnand protects living environment. It improves transportation efficiency, balance transport demand and supply, promotes socio-economic transition. Low carbon transportation system guided urban space layout development strategies include: quantity and quality improvement,element optimization, interior mechanism upgrading, low carbon transport structure and urban space structure connection. The strategy promotes low carbon transport system development, organizes rational urban space structure, and promotes low carbon and sustainable urban development.%低碳城市交通系统以节约资源和减少碳排放量、实现经济可持续发展和保护人类生存环境为出发点,提高交通运输效率、平衡供需关系,从而促进社会经济发展的低碳转型.在低碳城市交通系统引导下的城市空间布局模式优化策略主要包括形和量的优化、构成要素的优化、内部作用机理的优化,以及低碳交通结构和城市空间结构的有效结合4个方面.这一优化策略在推动低碳城市交通系统建设的同时,合理组织了城市空间结构,促进了城市低碳、可持续发展.
