Poyang Lake in Jiangxi Province is the largest freshwater lake in China, however, it has now become the grassland of Poyang Lake, and has become a holy place for aunts and Internet celebrities.
Every year in August, just over 1,000 square kilometers of Poyang Lake's water body remains, and the rest is a large area of grassland.
In order not to waste resources, some people have proposed that it is okay to harvest large areas of pasture, or nomadic herding, in fact, if you think about it carefully, it should be possible in theory, but as soon as this proposal was exported, it was banned?
Poyang Lake is an important freshwater lake
Poyang Lake is one of the main tributaries of the middle and lower reaches of the Yangtze River, and it is also a water-flowing, through-flow and seasonally important lake in the Yangtze River Basin.
It is not only the largest freshwater lake in China, but also one of the most important wetlands in the world, and it is rich in natural resources and has a unique geographical environment, which attracts a large number of tourists every year.
Visitors who come here can not only enjoy the sunset, but also enjoy the grassland of Poyang Lake, which is blown green by the spring breeze, with both water and grassland, which can really be described as a scene to see two different scenery.
This beautiful scenery also attracts a large number of birds to inhabit here, blending in with the beautiful natural scenery, not only that, but tourists can also visit ancient cultural sites and temples after enjoying the beautiful scenery, and feel the ancient cultural heritage and temples.
However, in the summer of this year, due to the decrease in water from five rivers such as the Ganjiang River in Jiangxi Province and the push of the water level of the main stream of the Yangtze River, the water level of Panyang Lake continued to fall, below the 8-meter extreme dry water level, and only 277 square kilometers of the lake area was left in the river area, meeting the blue warning standard for dry water.
From this point of view, the problem of water shortage in Poyang Lake is indeed more prominent, but I did not expect that Poyang Lake will be transformed and appear in front of the public in another form.
In the past, Poyang Lake was famous for "water", but now it is famous for "grass", and has become an endless prairie.
Although this seems to be a retreat from the lake, this is not the case behind the facts......
Returning the lake to grass
As the second largest lake in the mainland, Poyang Lake covers an area of 3,150 kilometers and has a high water level of more than 4,125 square kilometers.
But just this year, a large area of Poyang Lake suddenly grew green grass, becoming a "sea of grass", so why did Poyang Lake suddenly grow grass, and what harm did they have to the surrounding ecology, as well as the environment of animals and plants?
In fact, the reason why grass suddenly grows in Poyang Lake is because it has experienced a dry period, and the dry period is a period that every lake has to go through every year.
The dry season is also the dry season, when the surface water flow in the basin is depleted, and the length of the dry season is also irregular in a year, depending on the natural geographical and climatic conditions of the basin.
In fact, the biggest reason for the occurrence of this phenomenon in the end is mainly due to rain, if the climate of this place is humid and it rains a lot, the dry season will be interrupted, and if there are no raindrops for a few months, then the problem will come.
In some places, because the dry season is too long, sometimes the bottom of the lake will be exposed, which is not conducive to the growth of grass and trees, but this time Poyang Lake has grown a lot of grass during the dry season, and the reason behind this is because of the season.
The general dry period is usually during the Spring Festival and winter, which is also because of the lack of rain, and it seems that there is some truth in the saying that spring rain is as expensive as oil.
This season is not suitable for the growth of plants and trees, and there is not a lot of moisture in the soil, but the dry season of Poyang Lake this time is summer.
Although spring is the season of recovery, summer is the season when plants and trees are most lush, and the dry season is not the right season, and the moisture in the soil is sufficient for grass to grow.
It can be said that the time and place are favorable, less than a month of effort, Poyang Lake has become a prairie scene, you can see the endless prairie in the mainland, this is really not going out to have the prairie, but the people around Poyang Lake are happy, this place is also known as the holy place for aunts to check in.
After all, the lake has become a grassland, and it is better to see it than to hear it, and although such a scenery is beautiful, it is actually full of dangers.
By August, the grassland area of Poyang Lake had become larger, leaving the lake with less than 600 square kilometers of water to cover.
Although the arrival of the dry season has brought the place into another season, and spring is full of joy, in fact, it is the environment that is the first to be threatened.
Due to the long dry season of Poyang Lake, there is no grass in a large area of Poyang Lake, and the sediment at the bottom of the lake is scraped everywhere, even to Nanchang, resulting in many cities in the south experiencing sand blowing for several days, which brings a lot of inconvenience to people's travel.
Not only that, but the spread of wind and sand will also lead to the destruction of many pastures and fertile fields in the surrounding area, and in addition, there will be no water source in advance, resulting in a shortage of water around the lake, and grain production will also begin to decrease.
In addition, it will also have an impact on the survival of local wildlife, as Poyang Lake, as an "East Asia-Australia" "East Asian-Australian" waterbird wintering ground, is also home to nearly half of the Yangtze finless porpoise.
But now the environment is affected, and there is also a certain impact on these inhabited animals.
Although Poyang Lake in the sea of grass has become a holy place for check-in, will the appearance of endless moss and grass form a vicious circle in later life? This is obviously an unknown quantity.
But then again, a large part of the reason why Poyang Lake has become a Poyang grassland is not only because of the climate, but also because of humans.
According to the data, in the previous decade, the amount of sand mined in Poyang Lake reached 2.154 billion tons, which dried up day and night, so that all the sediment of the lake for hundreds of years was hollowed out.
As a result, there is less sediment below, and not only the amount of water is affected, but also the ecological balance of the water is also affected.
There are more sand quarries, and the money earned is becoming more and more, and some people around look red-eyed, and they have begun to do their old business, enclosing lakes and making fields, and the people who have no land with slow hands have begun to fill in the lake to make land, occupy wetlands, and illegal cofferdams are commonplace.
The above behavior can be very difficult to supervise, especially sand mining, as long as there is a broken boat, plus a machine, the sand in the lake can be extracted.
This also leads to a decline in water levels and volumes, coupled with climate problems, and the ecosystem is declining, so that the dry season also changes the time, resulting in endless savannahs.
But some people may wonder, since there are so many large grasses, why not circle them and feed them to cattle and horses, or cut them down and use them as fertilizer?
You must know that the grass here does not grow grass in the grassland, and the varieties including the surrounding climate are different, so I am afraid that the grass will not be adapted, and the grass has not eaten much, maybe the cattle have been eaten by unknown parasites.
Then some people would suggest that since the cattle could not go to the grassland to eat, why not cut all the grass and feed the livestock?
First of all, the season for grass is not right, and the geology below is not suitable for large machines, so even if it is an endless grassland, there is still no machine on this holy place to check in.
If a machine comes forward, it will definitely be noticed by the Environmental Protection Agency, so that there will not be so many tourists next year.
However, everything that happens here is not broken, but continuous, and when the moss grass of Poyang Lake is submerged in the water during the flood season, in fact, they are not "drowned", but are in sleep mode, and then take root and sprout again the following spring, becoming spring grass, turning this place into an endless prairie.
Although the prairie of Poyang Lake can only be a tourist destination, it should also make rational use of grassland resources, unremittingly take the road of ecological priority and green development, and at the same time protect the ecological water balance of Poyang Lake, it should also scientifically standardize the use of grass resources, correctly guide the society to participate in the development of grassland ecological products and grassland tourism, and let all people know how to protect ecological resources.
