Over -police experts in the longest inland river section of my country's longest inland river: abnormal high temperature weather exacerbates glacier ablation

Cover Journalist Di Rui Leisco Reporter Feng Rui intern Zhu Wenli

The Tarim River, the longest inland river in China, the area of ​​the basin exceeds 1 million square kilometers. In Xinjiang, the oasis south of Tianshan basically depend on its irrigation. Once, when it comes to this river, many people think of beauty and Populus Populus forest. This year, the Tarim River appeared in the news, but it was more related to the flood.

On August 21, the National Defense General Office and the Emergency Management Department organized discussions. Cover reporters noticed that clear requirements were put forward for the super police river section such as the Tarim River. According to Xinhua News Agency, a few days ago, the Tarim River dry flow and its source of the Hetian River, the Yeerqian River, the Aksu River, and the Weigan River occurred above the flood above the flood.

Why is there a "super police" in the Tarim River? What about its current situation?

What is the Tarim River?

The Tarim River, located in the north edge of the Tarim Basin in southern Xinjiang, is my country's longest inland river. According to Tan Jing, a senior engineer of the Tarim River River Basin (Tower Management Bureau), since August, the middle and upper reaches of the Tarim River are close to or exceed the alert traffic. On August 13, the maximum flood peak flow of the Tarim River's dry section reached 1830 cubic meters per second.

"There have been floods in previous years in memory." Mr. Liu in Alar City told the cover journalist. "The flood of the Tarima River has continued for more than half a month." The Tarim River Bridge section was observed- "still turbulent." According to him, the flood situation also occurred last year, but this year is not as big as this year. The relevant departments have taken anti -puzzle measures in the river embankment.

"Our peak scheduling through the reservoir and the joint scheduling of the source rivers drop the peak value, and it has been controlled at about 1600 cubic meters per second." Tan Jing said that controlling the flow of water at about 1600 cubic meters per second can ensure that the dry flow can be ensured There will be no major problems along the line. Data show that as of 12:00 on August 23, the traffic flow of the dried surface of the Tarim River was 1070 cubic meters per second, showing a downward trend.

On August 23, Zheng Xin, Director of the Water Disaster Disaster Defense Division of the Water Resources Department of the Xinjiang Uygur Autonomous Region, told the cover journalist that the water flow of the Tarim River has fallen, but some of the river sections of the dry flow are still in a super police state, such as the upstream Xinqu Manfang Station Station. The observed traffic exceeds 1300 cubic meters per second, and it is still in the stage of flood control emergency treatment.

On August 23, the Tarim River Basin dry flow administration bureau and Weili County Tarim Township government and surrounding water households reinforced the water to the north bank of the Tarim River

Why is there a flood situation?

The cover reporter learned in the interview that the flood situation in the Tarim River was "mixed flood", which was mainly formed by continuous high temperature weather caused melodia melting water to increase the rainfall. In addition, the reporter noticed that the relevant reports of Xinhua News Agency also mentioned that the flood situation was "affected by continuous high temperature and strong precipitation in mountainous areas."

It is understood that the dry flow of the Tarim River itself does not produce flow. Its runoffs mainly come from the three source flows of the upstream of the Aksu River, the Yeerqian River, the Hetian River, and the input of the downstream peacock River.

"The hydrological cause of this flood of the Tarim River is the continuous abnormal high temperature and the weather exacerbate glacier ablation, which leads to an increase in the flow runoff." The increase in extreme weather events caused by global climate change and high -intensity human activities is also one of the reasons for floods. "

Tan Jing told reporters that the flood in the Tarim River was caused by short -term heavy rainfall in the mountains and the melting floods of glacier ice and snow. Rare. "Zheng Xin also mentioned that this time the Tarim River flood situation is a bit special compared with previous years." The floods in the past year mainly occurred in late July and early August. Many. "Tan Jing said that in the long run, in recent years, the amount of water from the Tarim River has a large amount of water, but it is still in a stable trend.

Is the risk controllable?

In response to the differences between the inland river and the Yangtze River and the Yellow River, Tan Jing said that the Tarim River is a seasonal river, and its dry flow is mainly from 7, 8, and 9 months, so the flood season is particularly concentrated. "For us, this time is in the flood prevention every year, and the experience is relatively rich. There is basically no danger that happened this year."

The Xinjiang Water Resources Department also stated that the overall risk of the Tarim River flood conditions is controllable and did not cause much loss.

In response to the situation of the "Super Police", since August 16, the Tarim River Basin Administration regulates the flow of the Uluvati Reservoir and the Altash Reservoir in the upper reaches of the Heada River, and coordinate the upstream Shimaka Reservoir upstream of the Yeerqian River to stop generating electricity, stop the floods, and at the same time Increasing the Aksu River, Yeerqian River, Kalakhar River, Yulong Kashi River Irrigation District, water diversion and coastal ecological hydration capabilities, reduce the amount of water leakage, and ensure that the flow of the river in the Sanhe convergence is controlled within 1,600 cubic meters per second.

In addition, according to the China News Network, during the flood of the Tarima River, Payin Guo Leng State Wheeling County passed project measures such as dredging floods and piles of dams to pile up the 150,000 acres of natural artpu Yanglin.On August 14, the sluice of the full reservoir in Shaya County slowly released the water flowing into the Tarim River.

The reporter learned from the Tarim River Basin Administration that from August 10th to 17th, a total of 928 million cubic meters of floods were added to the Aksu River, Yeerqian River, and Hetian River, with a total of 717 million cubic meters of floods, and the flood utilization rate reached 77%.Among them, agricultural irrigation was 176 million cubic meters; Populus euphratica forest introduced the flood to replenish 203 million cubic meters; the reservoir water storage was 338 million cubic meters, achieving maximum benefits of flood resources.

On August 23, the cover reporter learned from the Emergency Management Department that the National Defense General Office and the Emergency Management Department emphasized that in the defense of the super police super -guarantee rivers such as the Tarim River, we must do a good job in the warning and early warning of meteorological and hydrological monitoring.The risk is 24 hours a non -interruption, and the rescue force and supplies are preset to ensure the efficient disposal of the danger.
