Why is China building high-speed rail on a large scale?

China ranks third in the world, fourth in the United States and fifth in Australia. Few countries are bigger than China.

Russia's population 1 100 million, slightly more than Guangdong Province and Japan.

The population of Canada is over 30 million, slightly less than that of Fujian Province in China.

The population of Australia is only over 20 million, which is equivalent to Shanghai in China.

It is obviously unrealistic for these countries to build high-speed rail on a large scale. They have no one, either near the North Pole or the South Pole, or too cold or too hot. Living in the wild is unrealistic and costly. Moreover, the population of these countries is concentrated in a few cities, and even if these cities are connected by high-speed rail, it is difficult to form a scale. If you look at the map, there are only a few lines.

Then the fourth place, the geographical condition of the United States is slightly close to that of China. Compared with those three sparsely populated countries, the population of the United States is more than 300 million, less than a quarter of that of China, but at least it is a little close. China1400 million people, the transportation of the United States mainly depends on civil aviation and highways, especially expressway. Railways are mostly used for freight transportation, so there is no such high demand for speed. It doesn't matter if the goods arrive half a day late, and the goods themselves won't feel tired. But for passenger transport, the experience of 12 hours is completely different from that of 4 or 5 hours. Red-eye overnight passenger transport is very tiring, and it usually takes 2-3 days to recover. If it is jet lag, the one-hour jet lag usually needs to be adjusted by one day, and the bus (Fuzhou-Guangzhou/Shenzhen) needs 13 hours. I have taken a 13 hour green leather car (Guangzhou-Shenzhen-Shangrao) and a 26-hour plane (Melbourne-Edmonton, with three stopovers). Generally speaking, people who travel more than 10 hours will feel very painful and uncomfortable. If they travel for more than five hours, their fatigue will obviously increase by several grades. If the journey is less than 5 hours, they won't. Off topic, keep talking about America. The American people rely on civil aviation and highways to complete passenger transportation. This is because the United States is a country based on fuel, and planes and cars burn oil. Yes, the United States is a major contributor to global warming, including American fat people, who also heat the world 24 hours a day. Therefore, the president of the United States pays great attention to controlling the oil supply. In order to ensure the domestic oil supply in the United States, President Bush did not hesitate to launch two Gulf wars. The United States is also exploiting shale oil and other resources, because domestic transportation in the United States depends on oil supply, while China and even East Asia have no oil resources. Although China also produces oil, it is not enough to support the overall transportation demand of China. What should we do?

Importing oil is a method, but it is a big oil producer in the world, and most of it is pinched by the United States. The United States grabs oil all over the world, because the United States itself is a big oil consumer, so China's thirst for oil will inevitably touch the interests of the United States, and Americans will certainly not be polite to China. then what

Besides oil, there are other alternative energy sources, such as electricity, which can replace oil as the energy supply for transportation in China, such as electric cars, subways and railways that used to burn coal. Later, after the electrification reform, electric trains ran on the tracks in China, so electricity is an alternative energy source, which can support the traffic demand in China and replace oil.

China is building a large-scale high-speed subway, as well as a large hydropower station for power supply and coal. The main purpose of coal mining in China is for thermal power generation. At the same time, China is vigorously promoting wind power generation and building windmills in various places, such as the offshore of Pingtan, Fujian. It is optimistically estimated that by 2030, China wind power can replace coal to supply all the electricity demand in China [1]. Electric cars, subways and high-speed trains are big consumers of electricity. Compared with the oil supply in the hands of the United States, the electricity brought by geomantic omen is obviously much more reliable and cleaner. Therefore, China is investing heavily in high-speed rail, hydropower stations and wind farms in order to meet the transportation needs of our people and avoid competing with the United States for oil resources.

Similar to China, there are European countries and Japanese countries, but the high-speed rail construction in these countries was actually completed in the last century. France's tgv and Japan's Shinkansen were both built in the 1990s before the reform and opening-up, and their land area itself is not large. The whole of Europe adds up to the area of China, not to mention that Europe is divided into dozens of countries, so in the face of the completed rail transit,
