Poyang Lake "shrunk" by nearly 70% during the period of 65438+ 10, and its riverbed became a "grassland". Where did the water go when the locals drove?

Poyang Lake during the period of 65438+ 10? Shrinkage? Nearly 70%, the river bed has changed? Grassland? The locals galloped away. Many people are curious about where the water has gone as the largest freshwater lake in China. For this problem, I personally think that water has gone to two places; First, the evaporation and loss of water have accelerated, and the demand for water in surrounding towns and farmland has increased, making the water level worse and worse.

The continuous high temperature and dry weather this summer has made the water levels in several river basins in China reach the lowest in history. The water level of Poyang Lake dropped by nearly 70% in the flood season, making it the lowest water level ever recorded. The water level drops, the riverbed is exposed, and the grass grows slowly. The grass is hard enough to support cars flying on it. With such a large number of lakes disappearing, it is most likely to go to the following two places.

First, the continuous high temperature intensifies the evaporation of water. The continuous high temperature weather this year has accelerated the evaporation of ground water. Poyang Lake basin is very large. Under the continuous high temperature baking, if the daily water evaporation is counted, I believe this figure will be shocking.

In the face of hot and high temperature weather, water is evaporating every day, and with the increase of temperature, the evaporation efficiency is improved. A large part of the lake water disappeared in Poyang Lake was evaporated by high temperature and disappeared in the form of water vapor.

Secondly, Poyang Lake supplies towns and farmland, and the water intake greatly increases the existence of Poyang Lake, which plays a very important role in drinking water in surrounding towns and irrigation of farmland. In the continuous high temperature weather, whether it is urban water or farmland irrigation water, the water demand will increase greatly. Water is continuously taken from Poyang Lake, and the amount of water taken is gradually increased, so that the water level of Poyang Lake will continue to drop, and finally it will become what we see.

If there is a steady stream of water flowing into Poyang Lake, as the water is taken away, there will be running water to fill the gap in the next moment. When the whole basin is in a state of drought, there is little water to replenish. Without the source of living water, the storage capacity will naturally shrink bit by bit.
