Xinjiang’s ecological water transfer broke the record and how many Tianchi “supplies” southern Xinjiang in one year?

In 2017, the entire Tarim River basin in Xinjiang delivered a total of 2.469 billion cubic meters of ecological water, exceeding the water delivery volume of nine Tianchi Lakes in the Tianshan Mountains. The vegetation on both sides of China's longest inland river has regenerated, and the downstream " The "Green Corridor" has been gradually restored, and Taitema Lake in Weulu has regained its beautiful scenery of vast expanse of blue waves.

According to the latest information, in the past year, the lower reaches of the Tarim River transported 1.214 billion cubic meters of ecological water, replenished 633 million cubic meters of water to the key Populus euphratica forest areas in the basin, and replenished 622 million cubic meters of ecological water to the Kongque River. The cumulative total of the entire basin Transport 2.469 billion cubic meters of ecological water and restore 503 kilometers of rivers in the middle and lower reaches that have been dry for 15 years.

The latest monitoring data from the Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, shows that Xinjiang’s ecological water transfer in 2017 set three historical records: the earliest ecological water transfer, the largest water volume, and the fastest discharge head. Among them, the area of ??Taitma Lake and surrounding wetlands currently reaches 511 square kilometers, forming the largest water surface since the ecological water transfer; the ecological water transfer to the lower reaches of the Ta River has exceeded the 1 billion cubic meter mark, marking the first time since the Tarim River stopped flowing in 1972 and 2000. This is the year with the largest amount of water released since the implementation of ecological water transfer. In addition, ecological water transfer irrigates approximately 2.72 million acres of Populus euphratica forest through flood diversion, affecting a vegetation area of ??5.64 million acres.

The 1,321-kilometer-long Tarim River is located in the arid southern Xinjiang. It is the longest inland river in China and the "mother river" for the people of southern Xinjiang. Since the 1950s, due to the disorderly development and inefficient use of water resources, nearly 400 kilometers of river courses downstream of the main stream of the Tarim River have been cut off, the groundwater level has dropped, Taitma Lake in the tail end has dried up, large areas of Populus euphratica forest have died, and many places on National Highway 218 have Sections of the road are often buried by quicksand, and the downstream green corridor is on the verge of destruction.

In June 2001, the State Council approved the "Report on the Recent Comprehensive Management Plan of the Tarim River Basin" and invested 10.739 billion yuan to save the ecological crisis in the lower reaches of the Tarim River. As the comprehensive management project continues to advance, Xinjiang has transferred water to the lower reaches of the Tarim River 18 times. So far, a total of 6.88 billion cubic meters of ecological water have been transported, of which the water volume at the Challa section in the lower reaches of the Tahe River this year has reached the largest value since hydrological records began, reaching 1.586 billion cubic meters.
