浅谈如何发展符合中国国情的高速铁路（How to develop high speed railway in line with Chinas national conditions） At present, driven by the high-tech, due to the high speed railway transport capacity, speed, safety, comfort, small footprint, energy saving, emission reduction, environmental protection and high economic benefit is more prominent, the development of high speed railway is a common trend in the development of Railways in the world. In this paper, from the point of view of sustainable development, it analyzes the technical and economic advantages of high-speed railway, and discusses how to develop high-speed railway in line with Chinas national conditions. First, the technical and economic advantages of high speed rail 1, covering less For transporting an equal number of passengers, the infrastructure required by the high-speed railway covers only 25% of the area required by the highway. 2, save energy consumption The unit energy consumption of the high-speed EMU is less than 3% of the Boeing 747, and 20% of the private car energy consumption. High speed rail is the only mode of transportation that uses electricity, and it uses renewable energy sources, such as nuclear power, solar energy, or water power. However, the dependence and consumption of other modes of transportation on petroleum resources will further aggravate the structural contradiction of energy supply. 3, pollution is light, emission is low Road and air transport not only generates air pollution, but also releases carbon dioxide, which exacerbates the global greenhouse effect. According to the test data of major cities in Europe and America, 40% - 90% of the major exhaust gases in cities come from automobile exhaust. As the high-speed railway is electric traction, the atmosphere will not cause pollution, and basically no harmful gases will be emitted. At the same time, the high-speed railway is less noisy than the other transportation modes, such as highway and aviation. In order to reduce the noise effects of
