Falling 15 meters!The water level in the Wuhan section of the Yangtze River reached a new low, which has no effect on the water taking

The Yangtze River Daily Da Wuhan Client August 31st News In the past few days, the water level of the Wuhan section of the Yangtze River continued to visit. At 2 am on August 31, the water level in Hankou Station in the Yangtze River was 14.99 meters, falling below the 15 -meter mark. At 17:00 on the same day, the water level at Hankou Station in Yangtze River was 14.87 meters, which was 8.65 meters lower than the dates of the same period over the years, which was 2.06 meters lower than the lowest water level in August.

According to hydrological predictions, the water levels of the Yangtze River Hankou Station will be 14.85 meters, 14.75 meters, 14.69 meters, and 14.67 meters in the next 4th (September 1st to 4th), and still show a downward trend. According to the relevant person in charge of the Office of the Municipal Flood Control and Drought Resistance Headquarters, the average historical water level in Hankou Station in Yangtze River was 23.45 meters in August. The lowest water level in August appeared on August 30, 1972, 16.93 meters. Under normal circumstances, the lowest water level in the Wuhan section of the Yangtze River appeared in January and February each year, and the average values ​​of January and February were 14.32 meters and 14.28 meters, respectively. The water in the Wuhan section of the Yangtze River fell below 15 meters at the end of August, which was rare in history.

The downside of the water level does not affect the safety of water removal and the supply of tap water

The relevant person in charge pointed out that due to the weakening of rainfall and the weakening of high temperature intensity, the drought in Wuhan has eased. According to statistics from the municipal agricultural department, the city has not been submitted to the agricultural disaster situation. The decline in the dry flow of the Yangtze River has a certain impact on drought resistance in Xincheng District, such as the Yangtze River and the Han River to protect the drought -resistant water sources of agriculture in Hannan, Cai Dian. The drought resistance of drought -resistant water anti -drought resistance work has limited impact.

The water level is so low. Does Wuhan's water supply facing a situation of waterlessness? The relevant person in charge of Wuhan Water Affairs Group said that at present, the downside of the water level does not affect the safety of water removal. The production operation of 12 water plants owned by the Municipal Water Affairs Group is normal, and the urban water supply is smooth and orderly.

"The water removal process of tap water has taken into account various natural factors, which can completely cover the demand for water. At present, the citizens do not have to worry about waterlessness." The relevant person in charge of the Municipal Water Affairs Group introduced that there are mainly the water selection methods of 12 water plants owned by Wuhan Water Affairs Group. Two types: floating ships take water and well -sharing tube. Among them, the three water plants of Baishazhou, Zongguan, and embankment use floating boats to take water, and the other nine water plants use well -to -use water to take water. The floating ship's water takes the water -based rocker liaison tube, which can adjust the height of the water picking by itself with the level of water level. The water pipe is buried deep under the water and penetrated into the water of the river, which is basically not affected by the water level.

"Flood Reverse Period" will have a certain impact on the water ecosystem of the Yangtze River Basin to a certain extent

Regarding the current low water level in the Wuhan section of the Yangtze River, Liu Jiantong, an expert at the Institute of Aquatic Institute of Chinese Academy of Sciences, pointed out that this year, the Yangtze River Basin shows a rare flood season. At present, the Yangtze River dry flow, Dongting Lake and Poyang Lake water level have the lowest in the same period. "Dongting Lake and Poyang Lake belong to the Tongjiang Lake, and its elimination function will be affected to some extent. However, in the Wuhan section of the rivers and lakes, most of the gates have been enabled for man -controlled control. The environment is too much interference. "

"This time the flood period of the Yangtze River Basin has a long duration, a wide range, and strong intensity, which will not only affect the agricultural production and aquaculture of the coast, but also have a certain impact on the water ecosystem of the entire Yangtze River Basin." Expert Liu Huanzhang said that the high and low water level of the Yangtze River is closely related to the space of aquatic animal activity. Continuous high temperature and drought will cause a large reduction in the water surface. Animals and plants in the river and lakes and shallow water areas will lose their living places. At the same time, the reduction of water levels leads to a decrease in primary productive forces in the water body, the number of floats and plants is reduced, and the source of fish foods will also be affected.

Related data show that due to multiple factors such as high temperature time and less rainfall this year, the dry flow of the Yangtze River is 1 ° C-3 ° C higher than the same period of previous years (the temperature of different geographical location will float). Liu Huanzhang said that the rising water temperature will have a coercion effect on cold water fish that is more sensitive to temperature perception. For example, the rising water temperature may affect its spawning activity.

According to the recent information of the Water Conservancy Tribe Committee, according to predictions, the dry flow of the middle and lower reaches of the Yangtze River in September and the water levels of the two lakes and the water systems continued to fall. The Ministry of Water Conservancy will be based on anti -drought and long drought, closely monitor the rain, water, and drought conditions of the Yangtze River Basin. According to the needs of urban and rural water supply and agricultural irrigation water, water conservancy engineering water storage and hydration accurately.
