中文摘要：

本文简单回顾了中国城市化的发展历程，提出资源、环境问题已经成为中国新型城市化可持续发展必须解决的重大问题。而城市交通带来的能源消耗、环境污染和拥堵必须从现在就开始制定政策，采取措施，切实解决。因此，城市间和城市内交通向低碳绿色转型是新型城市化发展的必然选择。接着，我们特别探讨了影响汽车碳排放量的主要因素，最后概括了交通低碳转型的4种方式：提高汽车能源效率；交通运输结构向低碳方式转变；有效调控交通需求；创新交通运输管理方式。

英文摘要：

Tiffs article briefly reviews the development process of China＇s urbanization, and points out that resources and environ- mental issues have become major issues for sustainable development of China＇s new urbanization. Furthermore, urban transportation brings energy consumption, environmental pollution and congestion, and we must start now to develop policies and take measures to solve. Thus, inter- city and inner city traffic to a low carbon green transformation is the inevitable choice of new urban development. Then, we discuss the main factors affecting automotive carbon emissions, and finally summarize the transport of low- carbon transition in four ways： improve vehicle energy efficiency; struetural transition to a low carbon transport mode; effectively regulate traffic demand; innovative transportation management.
