China released 丨 This year, the water level in Taihu has fallen down all the way, and the launch of the Jiangji Taichi Water Project launched!Quoting the Yangtze River water is Taihu "thirst thirst"

China Net, July 21 (Reporter Zhang Yanling Correspondent Wei Yuxiang) At 11:00 on July 20, the Wangting Water Conservancy Hub opened the gates and diverted the water, and the introduction of the Jiangjitai water project was officially launched. The continuous stream of water was remitted into Taihu through the Wangyu River, and the water level in Taihu Lake slowly recovered, effectively supplemented the water storage capacity of Taihu Lake.

The water level in Taihu has decreased, and the risk of cyanosawang water has increased greatly

Different from previous years, the critical period of the flood prevention of Taihu this year is not only "flood prevention", but also to prevent "low water level". Water resources are limited, and the rainy period of Meiyu this year, Taihu in the flood season in 2022, the water level fell all the way.

Since June, the rainfall in the Taihu Basin is more than 70 % less than the same period of the year, especially the rainfall during the rainstorm period has severely lower, which has led to the continued decline in the water level of Taihu Lake. At 10 o'clock on July 16, the water level in Taihu was reduced to 3.16 meters, which was 0.40 meters lower than the same period of the year, the lowest in the same period in the past 20 years. According to the data released by the Ministry of Water Resources, the actual water consumption of the Taihu Lake Basin is about 33.35 billion cubic meters, which is far more than 17.6 billion cubic meters of local water resources.

According to the preview of the Ministry of Water Resources, when the precipitation of the Taihu Basin from July to August is less than 50 %, if the water diversion measures are not taken, the lowest water level in Taihu in late August will drop to about 3.00 meters. Decrease, may even approach the dry limit of 2.80 meters. If it is introduced to Jiangji, the water level in Taihu will reach 3.15 to 3.20 meters at the end of August.

According to the forecast of the meteorological department, the precipitation in the Taihu Basin has been relatively small in the near future. In addition, the high temperature impact, the water level in Taihu Lake has continued to decline, and the risk of cyanobacteria water has increased significantly.

The amount of water quantity scheduling was started, and the water of the Yangtze River was "quenching thirst" in Taihu Lake

In order to maintain the suitable water level of Taihu Lake, ensure the safety of water supply in the Taihu Lake, and the safety of Taihu Lake, the leading water project for the leading river Ji Tai is launched again. This project is a water resource dispatch project carried out by the Water Resources Department of Jiangsu, Zhejiang, Shanghai and other provinces and cities since 2002. Since 2002, the project is the water resource dispatch project. Water conservancy hub enters Taihu Lake. As of 2021, the water adjustment project had been introduced by Wangyu River 33.76 billion cubic meters through the Wangyu River, with an average annual 1.69 billion cubic meters, of which 15.10 billion cubic meters of Taihu Lake was entered through the Wangyu River, with an average annual 760 million cubic meter.

Given that the water level in Taihu Lake is significantly low and still shows a downward trend, it has reached the prescribed water adjustment conditions, and on July 16, the Ministry of Water Resources launched a scheduling of the amount of water in the summer of 2022. The joint scheduling of gate pumps in the Changshu Water Conservancy of Wangyu River, 1,000 to 16 million cubic meters of water in the Yangtze River, and 50 to 100 cubic meters per second. In addition, the Tai Pu Gate supply water at a flow of not less than 60 cubic meters per second to supply water in Zhejiang, Shanghai and other places.

"This time the amount of water volume can accelerate the exchange of water bodies in the north of Taihu Lake, which is conducive to suppressing the occurrence of cyanobacteria water in the lake and Bay. At the same time, it can also make up for the water supply and water supply protection in the basin. The relevant person in charge of the Ministry of Water Resources and Drought Disaster Defense said.

In the next step, the Ministry of Water Conservancy will closely monitor the changes in rainwater, strengthen consultation, and guide the Taihu Bureau to avoid flood control through various restrictions. When Taihu's water level exceeds the water level, the water level will be suspended in time. When the heavy rainfall process or the influence of Wangyu River's influence is encountered by sudden heavy rainfall, the water rains will be stopped in time, and the water drainage will be transformed in time. Bao people's livelihood safety.
