Later, due to flood control and development, the construction of Three Gorges Water Conservancy Project was started in 1994 and finally completed in 2006. In the past 12 years, the Three Gorges has basically changed its original appearance, but as a result, we have built the largest water conservancy hub in the world, which has not been surpassed so far.
The Three Gorges Reservoir is of great significance.
It can be said that the Three Gorges has become more practical, from the initial beautiful appearance to the practical functions of navigation, aquaculture, water storage, power generation, flood control and drought prevention. If you go to the Three Gorges, you can see the shocking water conservancy project-the Three Gorges Reservoir.
The Three Gorges Reservoir is an artificial lake which is completed by the Three Gorges Water Conservancy Project and is close to the Three Gorges Water Conservancy Project. Its total area can reach nearly 1 100 square kilometers, and it can hold nearly 40 billion cubic meters of water, making it the highest in the world. Moreover, the Three Gorges Reservoir is so rich in water resources that it naturally undertakes many functions such as water storage, flood control, aquaculture and hydropower generation.
In addition to the well-known hydropower generation, the Three Gorges Reservoir is also very powerful in water storage and flood control. The height of the Three Gorges Dam is 185 m, while the normal water storage height of the reservoir is 156 m, the maximum water storage height is 175 m, and the maximum flood control storage capacity is amazing 2.21100 million cubic meters. It can be said that the water storage and flood control function of the Three Gorges Reservoir ensures the life and property safety of more than 840,000 people in two cities and counties around the reservoir. Moreover, the aquaculture function of the Three Gorges Reservoir is also excellent.
Reservoir is also a paradise for fish.
But perhaps we can often hear rumors that there are water monsters in the Three Gorges Reservoir. After all, water monsters, as an anecdote, can attract people's attention. But the fact is that most of the legends of water monsters have been proved to be forged, just exaggerating some larger fish into giant water monsters to promote them. Therefore, the legend of the water monster in the Three Gorges Reservoir should also be false. Because the history of the Three Gorges Reservoir is not long, it is impossible to have prehistoric creatures or a history leading to mysterious waters. In addition, due to the functions of hydropower generation and flood control and water storage, it is impossible for water monsters not to be discovered.
In this way, the legendary monster in the Three Gorges Reservoir must refer to the big fish. I believe many people will be curious. The Three Gorges Reservoir has been storing water for almost 20 years, making it a paradise for fish. How big can the fish in the reservoir grow?
As we all know, the Yangtze River is the third longest river in the world, and its drainage area includes the whole area of southern China. It can be said that the water in the Yangtze River feeds half of China people. Because the geographical location is in the warm and humid south, the length spans the plateau, mountains, hills, plains and other landforms, which determines that the Yangtze River waters are rich in aquatic animal resources.
There are many fish.
In fact, in addition to the well-known rare species such as Baiji dolphin, Yangtze River paddlefish, Chinese sturgeon and giant salamander, there are 424 species of fish in the Yangtze River, among which 183 species are unique, which shows that the Yangtze River is rich in fish resources.
Moreover, the fish in the Yangtze River waters are not only rich in species, but also because the Yangtze River flows through complex and diverse areas, and the water is rich in nutrients and food, which helps fish grow, resulting in the fish in the Three Gorges Reservoir growing big, round and fat, and even some fish grow to amazing sizes.
For example, the Chinese paddlefish, which was declared extinct in 20 191February 23, is generally 2-3 meters long, and it is found to be 7.5 meters long and weighs more than 600 kilograms. Compared with people, it can be described as a monster, and it is indeed a bit of a monster. Acipenser sinensis is also an extremely dangerous species, smaller than Acipenser sinensis, but it can grow to 5 meters long and weigh 500 kilograms at the largest, and it is as huge as a whale in water. Sadly, due to the construction of the Three Gorges Project, especially Gezhouba, two extremely precious species endemic to the Yangtze River in China hindered the migration and spawning of Chinese sturgeon and Chinese white sturgeon, which led to today's extinction.
However, in addition to the above two famous fish, many lesser-known fish can also grow into giants in the waters of the Yangtze River, such as the giant herring, which weighs 2 12 kg, and the Chinese fish, which weighs more than 100 kg.
