摘要：在汽车需求日益增长、国际油价持续上涨、市区交通拥堵日益加剧，以及城市空气污染越来越严重的今天，正是改变土地利用观念与发展绿色交通的最好时机。首先指出目前全球面对能源短缺、环境恶化的种种问题，指出当前以石油为主的交通运输系统是不可持续的。要解决这些问题，并实现可持续发展，首先，必须降低油耗并寻求新的替代能源，开发电动汽车和氢燃料汽车为清洁、可持续的替代能源提供了出路。其次，要大力发展绿色交通，以减少二氧化碳的排放，并且辅之以交通需求管理等手段。最后指出，只有将城市规划、土地利用与公共交通系统紧紧相结合，促进以公共交通为导向的发展，才能够适应可持续发展的目标。

Abstract：The steady increase of vehicle ownership, coupled with issues like fuel price rising, traffic congestion worsening, and air pollution deteriorating, shows that it is now high time to promote green transportation and sustainable development. The current petroleum based transportation system is unsustainable. To solve these problems, we must reduce gasoline consuming and find new energy resources. Electric vehicles and vehicles powered by hydrogen fuels are one of the measures. Secondly, we should develop green transportation, and take TDM as alternative means to reduce CO2 emission. Urban and land use planning must promote public transportation and encourage transit-oriented development that is accessible and sustainable.
