Ministry of Water Conservancy: In the summer, the effect of leading the river Jeta is significantly cumulative to attract 291 million cubic meters of water in the Yangtze River water

On August 9, the Taihu Lake Basin Administration of the Ministry of Water Resources (hereinafter referred to as the "Taihu Bureau") held a press conference in the summer of 2022.

It is reported that since the launch of Jiang Jitai on July 16, the Yangtze River water has entered 291 million cubic meters, and the water has entered the lake 131 million cubic meters. The water supply to the two sides of the strait is 160 million cubic meters of water, and the water supply is 446 million cubic meters of water through other ports of Taihu Lake. The water adjustment effect is significant.

Yinjiang Jitai refers to the use of the backbone water conservancy project of the Taihu Lake Basin and other Taihu Lake Basin to lead the Yangtze River in the Taihu Lake and the surrounding river network, and combined with the use of Yuhong resources to supply water surrounding cities and downstream areas through the Taihu River and other cities. River and lakes flow, increase the amount of water resources in the basin, and improve the water environment.

This year, the rainy period of the Taihu Lake Basin was 6 days less than the year, and the rainfall was 75.4 mm, which was 69%less than the year. Since the plum, the Taihu Basin has continued to be sunny and hot. On July 16, the water level of Taihu Lake fell to 3.16 meters, which was 0.40 meters lower than the same period of the year. Facing a certain risk. To this end, the General Office of the People's Government of Jiangsu Province applied for the implementation of Jiang Jitai, and the water conservancy (water conservancy) department of the Taihu Bureau of Jiangsu Province, Zhejiang Province, and Shanghai Water Conservancy (Water) departments comprehensively and judged by the Ministry of Water Conservancy. The summer was launched this summer to lead Jiang Jita.

The relevant person in charge of the Taihu Bureau said that the leading Jiangji is an important part of the Taihu Basin's multi -target coordinated and coordinated scheduling, and it is an important means to ensure the safety of water resources, water ecology, and water environment in Taihu Lake Basin. According to reports, in the case of 20 % less rainfall in the basin since July 16, this time the leading Jiang Jita has effectively slowed down the trend of water level in Taihu Lake. On August 9, Taihu's water level remained at 3.13 meters. Water supply has created favorable conditions, effectively meeting water supply, agricultural production, shipping, water ecology, and water environment of water supply, agricultural production, shipping, water ecology, and water environment in the area of ​​the Wangyu River, around Taihu Lake, and the lower reaches of the Tai Pu River.

At the same time, Qingshui enters the lake to effectively improve the quality of the water environment in Taihu Lake. During this period of leading Jiangji, the average concentration of the total phosphorus in the lake was only half of the average concentration of the average concentration of the total phosphorus concentration of the total phosphorus of the Lake Canal, Chengdong Port, and Yincun Port in the lake. The average phosphorus concentration of the lake source. The introduction of the Yangtze River water with excellent water quality into Taihu Lake is introduced. On the one hand, under the self -purification of the lake body, the water quality will improve further and effectively improve the quality of the water environment in the northern lake in Taihu Lake; The amount of water entry into the lake by the polluting river in the area indirectly reduces the contaminated load entering Taihu Lake, and improves the overall water environment of Taihu Lake.

This time, Jiang Jita also accelerated the flow of water body flow in the Gonghu body of the lake in northern Taihu, improved the water power conditions in the lake area, to a certain extent suppressing the gathering of Gonghu Lake Lake Water, and reducing the risk of the epitaph of cyanobacteria. During this period of leading Jiangji, there was no large -scale cyanobacteria water phenomenon in Gonghu.

According to meteorological forecasts, the Taihu Basin will continue to be sunny and hot, high temperature and rain, and the water level in Taihu will continue to decline slowly, and the risk of water safety guarantee in Taihu Lake will further increase. The Taihu Bureau said that the next stage will continue to do a good job of leading Jiangji, and continue to highlight the overall targets of flood prevention, water supply, water ecology, and water environment.
