What did China do to make the lake dry for 50 years reappear?

Yuan Ye Lake, more than 30 kilometers northwest of Dunhuang City. Mongolian means Black Lake or Black Haizi, which is the terminal lake of Shule River and Danghe River. 20/KLOC-In March, 2007, Yuan Ye Lake, the largest lake in Dunhuang history, reappeared after 60 years of drought. Seen from a distance, it looks like the sea. For this Gobi city, which is always accompanied by yellow sand, this rare sight has recently attracted many people to go to Gobi to "see the sea". ?

In the long river of history, kharrazi and Lop Nur in Xinjiang, which flowed westward into the eastern edge of Kuntag Desert, played a great role in preventing the desert from moving eastward, maintaining regional biodiversity and ensuring ecological security in western Gansu. However, it began to dry up and shrink during the Yongzheng period of the Qing Dynasty. In the 1960s and 1970s, the Changma Dam, Shuangta Reservoir and Danghe Reservoir in Dunhuang were all built, and it dried up.

Being in a state of desertification for a long time, people can only see a saline-alkali land and a "sand lake". This is a lake that has been dry for 50 years. After drying for half a century, the blue waves finally reappeared. On March 27th, 20 17, it was reported that in the early spring of 20 17, a green wave appeared in Halanour Lake in Dunhuang, which had been dry for more than half a century. Yuan Ye Lake, located more than 30 kilometers northwest of Dunhuang City, was once the largest freshwater lake in Dunhuang history.

According to the statistics of Danghe River Basin Water Resources Management Bureau in Jiuquan City, Gansu Province, the ecological displacement of the two rivers is about 50 million cubic meters in 20 16 years. Winter freezes, spring melts, and blue waves reappear. This is also the result of human efforts. As long as people live in harmony with nature, we can protect our nature, which is also of great benefit to our own life ~
