Preface

China’s urban rail transit is facing great opportunities for development. According to preliminary statistics, more than 40 cities and thousands of kilometers of urban rail transit lines will be built and put into operation. While building urban rail transit with multi-level and line network, the concept of sustainable development has been paid more and more attention by the industry. To achieve sound and rapid development of China’s urban rail transit by adhering to economic development, clean development and safe development is also the embodiment of the overall requirements of our participants to seriously implement and vigorously promote the construction of ecological civilization, and to deeply implement the goals and tasks of energy conservation and emission reduction.

The operation cost of urban rail transit project is not only related to scientific and reasonable planning, construction and management, but also how to implement the design concept of energy conservation and emission reduction to all aspects during the construction. The energy-saving and emission reduction technology of urban rail transit engineering covers many systems and specialties, such as urban rail transit vehicles, power supply, electromechanical system and operation organization. How to systematically and reasonably implement and implement energy conservation and emission reduction design, actively consider the environmental pressure, energy crisis and other social problems brought by high energy consumption to our country, and take effective measures to give good control is the sacred mission entrusted to today’s subway builders and operators.

前 言

中国城市轨道交通正面临发展大机遇，据初步统计，将有 40 多个城市、数千公里的城市轨道交通线路将陆续建设和投运，在构建城市多层次、线网化的城市轨道交通的同时，可持续发展的理念也逐步被业界高度重视，坚持节约发展、清洁发展、安全发展来实现中国城市轨道交通又好又快发展，也是我们参与者认真贯彻、大力推进生态文明建设的总体要求，深入落实节能减排的目标和任务的体现。
       城市轨道交通项目运营成本的高低不仅与科学、合理的规划、建设、管理有关，更重要的是在建设期间如何将节能减排的设计理念贯彻到方方面面、点点滴滴，而城市轨道交通工程的节能减排技术涵盖了城市轨道交通车辆、供电、机电系统及运营组织等诸多系统和专业。如何系统性、合理性地全面落实及贯彻节能减排设计，为高能耗给我们国家带来的环境压力、能源危机等社会问题积极思考，并采取有效措施给予良好控制是这个时代赋予当今地铁建设者和运营者的神圣使命。
      鉴于技术水平及实践的局限性，本书内容如有不妥之处，敬请原谅并赐教，不胜感谢。
