February** Dynamic Incentive Program
Speaking of Dongting Lake, everyone must be familiar with it, because this Dongting Lake is our largest freshwater lake, and all kinds of life are nurtured in it.
But after reading the title, are there many people who are confused? Why did the 800-mile Dongting Lake become "a river".
It can be said that it has gone through a very long process from a lake to a river, and if it is the evolution of nature, then we can only follow nature, but the real reason behind this change is caused by our own man-made.
Dongting Lake a few decades ago and today's Dongting Lake can be described by the idiom "world is different", and it is not an exaggeration at all. Today, let's talk about the story of Dongting Lake turning into a Dongting "river"!
Whether it is for some people who love to read ancient books, or people who love to observe nature, they will understand the whole development process of Dongting Lake.
In ancient times hundreds of years ago, although it was a long time ago, there is still historical evidence to prove everything.
In the past, Dongting Lake was located in the Jianghan Plain, and in ancient times, it was nicknamed "South China Sea".
From ancient books, we can learn that as early as the pre-Qin period, the area around Dongting Lake was called "Yunmengze", and when I heard this name, I suddenly felt very tall.
According to our current name, at most, such and such a lake, such and such a river, who would have thought of using "Yunmengze" to call Dongting Lake!
Our excellent traditional culture does not stop at these, for our own culture, we must increase efforts to carry forward, to enhance our own culture exclusive self-confidence!
Although there are so many beautiful ancient names, there is no question about when the three words "Dongting Lake" were activated.
Unfortunately, there is no historical information to be found, and the person who took the "Dongting Lake" has disappeared.
There are also a lot of poems about Dongting Lake from ancient times to the present, all of which are about describing and praising the beauty of Dongting Lake.
Travelers who have been to Dongting Lake will surely experience the gentle ripples of water splashing on the surface of Dongting Lake under the leaves of the autumn breeze blowing slowly.
Speaking of Qu Yuan, his works contain poems about the beauty of Dongting Lake. Qu Yuan was a poet of Chu during the Warring States Period, and according to an online information search, it can be known that Qu Yuan's life was from 340 BC to 278 BC.
is over half a hundred years old, but he is still a very dedicated person!
In his poems, the word "Dongting Wave" is involved, which shows that before the good name of "Yunmengze" in the pre-Qin period, the name "Dongting Lake" had already appeared.
However, at present, at the historical level as we know, it is not possible to give an accurate answer!
Between the Qin and Han dynasties, due to the natural sedimentation of sediment, the river channel was blocked due to sediment sedimentation during the past 100 years.
So much so that the water that was originally going to flow to the entire "Yunmengze" began to irrigate the "Dongting Lake".
And because of the changes in the water flow of many rivers, the originally relatively small Dongting Lake gradually expanded to a range of five or six hundred miles over time, and this data was recorded in the Eastern Jin Dynasty.
However, there is still a certain gap between the five or six hundred miles of Dongting Lake and the eight hundred Dongting Lake.
Due to the continuous growth of Dongting Lake, the waterway transportation conditions around Dongting Lake are getting better and better, which has also driven the economic development of the surrounding areas to a certain extent!
In the Eastern Jin Dynasty, the area of the entire Dongting Lake was between five or six hundred miles, and it did not reach the eight hundred Dongting Lake in the reputation.
In the Tang and Song dynasties, we all know that in this era, economic development reached the most prosperous stage, and more attention was paid to the development opportunities of the Yangtze River Basin.
After hundreds of years of development, the water that was supposed to flow to "Yunmengze" basically flowed to "Dongting Lake".
First of all, the geographical location of Yunmengze is located in the plain, and after a long time without sufficient water flowing, most of Yunmengze has become a plain area.
The former water resources also made the land resources of this place very fertile, so it became the "best fertile land" in the mouth of the people.
Under the effect of these fertile fields, the planting industry at that time also developed very well, but if the planting industry was to be developed, it was necessary to further control the amount of flowing water passing through "Yunmengze".
This led to the behavior of "human intervention in the flowing water", allowing more water to flow into the "Dongting Lake", and the "Yunmengze" around him began to become more suitable for planting.
In this way, under the condition of "human intervention" by the common people, the "Eight Hundred Dongting Lake" completed its final form.
The superior fertile land has spurred the local planting industry and helped the local population get rid of the food problem.
After all, the people take food as the sky, and the big guy has solved the problem of eating, so the remaining plan is to continue to make money and seek development.
The large area of Dongting Lake also contributes to the development of local water conservancy and transportation and agricultural irrigation to a certain extent. This has created a situation where the local economy has gone further!
In the Ming and Qing dynasties, due to the sharp increase in sediment deposition in the Yangtze River basin, Dongting Lake near "Yunmengze" became an above-ground river, and the accumulation of sediment also made the area of Dongting Lake larger.
According to records, in the Daoguang period, the area of Dongting Lake reached 8,000 square kilometers, which means that the 800-mile Dongting was only a turning point, and the subsequent development was also very rapid.
However, in the past 100 years, we have begun to develop light and heavy industries, so that this glorious Dongting Lake has begun to show signs of shrinking.
From 8,000 square kilometers to 2,691 square kilometers now, this is even a three-quarter shrinkage.
Such a change is undoubtedly difficult to predict, as more and more sand is washed away from the river upstream, and the position of Dongting Lake downstream can only be forced to accept the sand washed down from the upstream.
And it continues to settle at this location, so that it is impossible for Dongting Lake to avoid being decomposed.
The more sand accumulates, the more it will be, and the more sand it will make Dongting Lake become multiple branches, which will make the 800-mile Dongting slowly lose its original glory!
In the world we live in, everything will eventually have a time, whether it is a good friend, there will be a last feast, even if it is a glorious Dongting Lake for hundreds of thousands of years, it will usher in its own end.
The great changes in Dongting Lake are mainly due to the Tang and Song dynasties, in which the economic development can be said to be very good.
At that time, people only thought about better economic development, and ignored the natural laws of nature, which led to the early destruction of the natural environment around the Yangtze River Basin.
In the following centuries, there was no effective way to deal with the problem, so the effects of the destruction continued slowly for hundreds of years.
The natural destruction in the upper reaches of the Yangtze River, such as soil erosion, has also been in a state of continuous deterioration, which has led to more and more sand flowing into Dongting Lake, which makes the bottom of Dongting Lake higher and higher, which is why the above-ground river is formed!
During the Ming and Qing dynasties, due to the continuous accumulation of sand, the water level of the entire Dongting Lake rose, which caused the illusion of 8,000 square kilometers.
In fact, at this time, the development of Dongting Lake has changed, and the impact of ecological destruction will slowly change our Dongting Lake little by little.
Although the area of this Dongting Lake is so large, and there is a lot of water flowing downstream, due to sediment settlement, there is only one outlet of the lake.
As a result, the amount of sediment settled is much higher than the amount of sediment discharged, which is one of the main reasons for accelerating the shrinkage of Dongting Lake!
In recent years, we have been building a lot of water conservancy projects, such as our Three Gorges Dam.
It is precisely because of this Three Gorges Dam that the amount of water entering the lake is getting less and less, and the ability to scour is gradually decreasing.
The sand that has settled at the bottom cannot be discharged efficiently, and although the sand is small, it has a great impact on the area around the river.
In some areas, measures such as "enclosing lakes and cultivating fields" have begun to make use of these natural resources, but in a short period of time, "enclosing lakes and cultivating fields" is indeed making full use of natural resources.
On the other hand, this matter is to stretch the timeline, which is an act of destroying the ecological environment of water conservancy.
Why do you want to build fields around the lake? This is mainly because the economic development at that time became so good that it wasFor a time, the local population surged, and food became a major problem, which caused the situation of blindly "enclosing the lake to create fields".
If the problem of food is not solved, the local economy will only stop developing or even regress, and in order to make everyone have enough to eat, the only way to cultivate land is through the fertile fields around "Yunmengze".
At present, the development of towns around Dongting Lake is still quite good, but if the ecological environment is to be restored, then the residents of the surrounding areas must be removed.
Because the price of returning farmland to the lake is that this piece is not suitable for people to live in, but it is very difficult to get everyone to follow the instructions!
After all, there are tens of millions of people living around Dongting Lake, and with such a level of population, it is really not possible to solve the relocation matter in the near future!
Dongting Lake has a long history, but due to its economic development, its own development has also been greatly affected.
The current Dongting Lake has become less beautiful due to the siltation of river sand, and in recent years, some experts have been trying to "return farmland to the lake".
However, as far as the current situation is concerned, it is still relatively tricky, and it is necessary to continue to work hard to restore the storage capacity of Dongting Lake itself through various methods!
I believe that in the near future, Dongting Lake will still stay there beautifully and continue to write legends!
