Lake Baikal water storage How many? Three Gorges reservoir can fill 600 available in Beijing by 5900
As we all know, the Earth is a huge "water polo" marine area accounts for more than 71% of the Earth's surface, only about 29% of the land area, because of the presence of water and air on Earth that makes the planet became the only known the existence of extraterrestrial life.
water storage capacity on Earth is huge, with about 1.386 billion cubic kilometers of water, and this volume only to the total volume of the Earth of 0.128%,
According to scientists showed a total water storage volume of about earth 1386000000 cubic kilometers, and the total volume of the Earth is approximately 4/3 * 3.14 * (6378) = 1.08623E + 12 cubic kilometers, that is to say the volume of water on Earth is about 0.128% by volume of the earth. In fact, according to this volume, the entire planet in the solar system, the amount of water in the body is not the biggest, or even less than a tenth of Ganymede (Europa) is, relatively speaking, Ganymede is known as the solar system a super "reservoir", with 15 billion cubic kilometers of water.
However, most of the water on Earth is sea water, which is what we call" salt water ", although a relatively large amount of water but fresh water reserves on earth is miniscule amount of total body water, and only about 3,500 cubic kilometers of reserves, but also liquid water with only 4.5 million cubic kilometers, with social progress, environmental pollution, whether it is on Earth sea water or fresh water have been seriously threatened, being further contaminated.
our country's water resources
according to the amount of water on Earth for all countries, China's water resources is still relatively scarce, far, Brazil, Russia, Canada, the top three, closely followed by China, the United States, Indonesia, Bangladesh and India breakdown after China.
our water system is more developed, the Yangtze River, Yellow River, Pearl River and Huaihe River, and some foreign flows into the river or is borders, the other is the Poyang lake, Dongting lake, Taihu lake, Hongze lake, Chaohu lake, Weishan and so on freshwater lakes, though these are the most abundant natural water reserves, but China is a populous country, so our per capita rate is still not high. Especially where water shortage is more so on the Loess Plateau of place.
According to the relevant information, the total amount of fresh water resources in my country is about 2.8 trillion cubic meters, accounting for 6% of global freshwater resources, it came in Brazil, Russia and Canada after that, the body mass from the point of view is really quite rich.
Qinling Mountains and Huaihe River as the boundary, the north less water, but it is very rich in water resources in the South, so we can We see that some large rivers and lakes are basically distributed in a slightly more southerly position.
largest reserves of fresh water a lake
Of course, talk about today is Lake Baikal, the lake is located in Russia. We also know, Russia to the world's largest land area of a country, across Eurasia, Russia is a vast country's most extensive global freshwater reserves, but only a Baikal freshwater reserves accounted for 20% of the world .
Baikal fall from the formation from the fracture, 636 Lake one thousand meters long, an average width of 48 km square area of one thousand 31500 meters, the area equivalent to two area of Beijing and a total area of Beijing is 16410.54 km².
Lake Baikal is the ancient Chinese "North Sea", it was demoted Su Wu shepherd places, Kangxi and Qianlong of the Qing Dynasty Between gradually invaded Russia. The lake area is not the biggest, but it is the deepest lake, the deepest depth of 1637 meters, water storage capacity of 23.6 trillion cubic meters. The lake capacity equivalent to approximately 24.58 times the average annual runoff of the Yangtze River, the Three Gorges Reservoir 600 times, but also the equivalent of 33 times the capacity of all our lakes and, if in accordance with our water consumption 4 billion a year in Beijing square to count enough water in Beijing in 5900.
What makes Lake Baikal water storage so big?
First, due to geological structure determined Baikal, Baikal is a concave portion of the valley off, is a deep underground depths of 15 to 20 km large cracks. And according to geological exploration, Lake Baikal and its catchment area is the world's a very unique geological system. After thousands of years of evolution, making Lake Baikal has become the world's largest freshwater lakes, a water storage.
Baikal 336 surrounding rivers into the lake, river basin area of 560,000 square kilometers, flows Selenggehe Baikal water accounted for more than 50%.
because the impact of people's life and production, Lake Baikal surrounding environment once affected, local also established a number of security measures, the ecological environment in order to protect the lake do.
according to the situation in China, because the South to North water provided a guarantee, some users said that if the repair from Lake Baikal drains lead directly to a northern China, and is not able to alleviate the water problem to a greater extent in North people do?
Do you think this plan feasible?
