The river bed became a grassland. Why is Poyang Lake shrinking so badly?

The reason why Poyang Lake has shrunk so much is caused by the continuous high temperature weather. The riverbed has become a grassland, and the shrinking water body has also worried the local people. Affected by the continuous high temperature weather, the water level of Poyang Lake continued to drop, and the wide water surface turned into grassland. The grass has grown two or three centimeters, and it can even run on it. The area of Poyang Lake has shrunk obviously, and the drop of water level directly affects the drinking water problem of residents along the line.

1. The serious shrinkage of Poyang Lake is caused by extreme high temperature weather and less precipitation.

Not only the water level of Poyang Lake has dropped, but also the water levels of many rivers in China, and droughts have occurred in many places, all because of the continuous high temperature weather. Many cities in southern China have reached a high temperature of 40 degrees, which is due to the influence of subtropical high. It also caused insufficient rain, and it will last for a long time and cannot be alleviated.

2. The serious shrinkage of Poyang Lake is also caused by the fact that the evaporation on the lake surface is greater than the precipitation and the river water supply is insufficient.

The continuous high temperature has also caused the lack of irrigation and drinking water for crops along the lake, resulting in reduced production. Poyang Lake has been hard to find water. In addition, it is the dry season of Poyang Lake, and the water level will be lower in the dry season. This year's special circumstances will lead to a lower water level in Poyang Lake. This is not a good phenomenon. Artificial rainfall was adopted to alleviate the local drought.

In a word, the reason why Poyang Lake has shrunk so much is because of climate change. Under the background of global warming, extreme high temperature appears in many places, and it is even higher in summer due to La Nina phenomenon. Many areas in the south of China have low terrain and sultry climate, and the water level drops due to multiple effects. The global climate is changing, which is one of the reasons why the riverbed of Poyang Lake has turned into grassland. If global warming continues, the situation will be even worse next year.
