On August 25, the Wuhan Municipal People's Government held a press conference to introduce the relevant situation of the city to carry out drought resistance. Jimu Journalists learned from the press conference that there are currently 202,000 mu of drought in Wuhan. Through scientific scientific scheduling of water engineering, a total of 144,100 acres of drought were relieved, accounting for 71.3%due to drought disasters, and fully played the benefits of comprehensive drought and disaster reduction in water conservancy projects.

Since the plums on July 7, Wuhan has continued to have high temperature and rain, and the rainfall is more than 40 % less than the same period of the year. The amount of water from the Yangtze River is 20 % to 80 % less than the same period of the same year. At 8 o'clock, the water level in Hankou Station in the Yangtze River was 16.26 meters, which was 7.52 meters lower than the average dates of the same period over the years, and 0.67 meters lower than the lowest water level in August.

According to the information provided by the agricultural department, there are about 3 million acres of crops in Wuhan City, and the current drought area accounts for about 1.9%of the area of ​​Tiannong crops. As of August 25, the city has an area of ​​57,900 acres of disasters due to drought disasters (07,400 acres of disasters).

Cheng Jianjun, deputy director of the Wuhan Water Affairs Bureau, introduced the flood prevention and drought -resistant work. Cheng Jianjun, deputy director of the Wuhan Water Affairs Bureau, introduced that the city prepared early to coordinate drought resource resources, scientifically dispatch various types of water projects, and reserve water for drought resistance. Especially in several key rainfall at the end of the rainy season, instruct all relevant areas to make full use of water conservancy engineering facilities such as lakes, reservoirs, Tangyan, and Hong Kong canal, and make every effort to reserve the drought -resistant water source. It was reported to the municipal government to arrange 30 million yuan in special funds in advance to support the construction of short -board projects for small farmland water conservancy infrastructure in the city.

At the same time, comprehensively collect and report drought information in a timely manner, provide scientific basis for discharge and decision -making, dispatch the city's water conservancy projects, and ensure water sources in multiple ways. As of August 25, 769 facilities such as irrigation pump stations, gates, reservoirs and other facilities in the city were used for irrigation, diversion, and water adjustment. The city's irrigation water volume was 240 million cubic meters, and the irrigation area was 1.03 million mu. At present, a total of 202,000 acres of drought in the city. Through scientific dispatching of water engineering, a total of 144,100 acres of drought were relieved, accounting for 71.3%of the disasters due to drought disasters, which gave full play to the efficiency of comprehensive drought and disaster reduction in water conservancy projects.

Can meet the needs of residents' living water

Wuhan City has made every effort to ensure living water, and adopts a variety of emergency measures such as adding pressure pumps and tube network water pressure to ensure the demand for water for residents. In the case of emergency situations such as large or long -term stops, effective measures are taken as soon as possible to quickly coordinate and deal with. There are 42 water plants in our city, with a total water supply capacity of 6.58 million tons/day. Since August, the city has an average daily supply of 5.275 million tons, and the water plant load rate is 80%. The water supply condition is generally stable.

Since the summer, the demand for residents' living and production water has increased significantly. From July to August, Wuhan's maximum water consumption in a single day has reached 5.449 million tons, which is over 324,000 tons from the highest single -day water consumption in 2021, reaching the highest level of history. At present, the city's water supply situation is generally stable, which can meet the demand for living water for residents.

Cheng Jianjun said that it will continue to increase investment in the construction of water supply infrastructure, continue to carry out updates of old water supply pipe networks, and continue to implement the transformation of secondary water supply facilities in residential houses to ensure that citizens can drink "safe water, high -quality water, assured water" At the same time, he also called on citizens to join hands to protect water resources and develop a good habit of saving water.

Experts go deep into the field to guide scientific irrigation

Tang Jichao, deputy director of the Wuhan Agricultural and Rural Bureau, introduced that in recent years, there have been frequent frequent occurrence of extreme catastrophe weather. In 2019, Wuhan City suffered a drought in Fuqiu. In 2020, it was a major heavy rainfall in 50 years. This year, it is a historic high temperature drought. The weather has a certain impact on the growth of crops. As of now, the city has suffered 202,000 acres due to drought. After the disaster, the city has invested 9,742 yuan for drought resistance, and 64 guidance groups were established. 4,979 agricultural technicians were organized, 46,000 people were dispatched to the front line to carry out drought resistance work, and 144,100 acres were lifted. The area is still 57,900 acres, accounting for about 2%of the area of ​​farming crops.

According to agricultural expert analysis, this year's drought showed four characteristics. One is that high temperature heat damage and water deficiency and drought lead to decline in the strong rate of crops such as rice and soybeans, and the dark disaster is greater than the open disaster. Crops in the irrigation area; Third, the degree of drought in dry land is greater than that of water field crops; the fourth is that the forecast may have a certain impact on the next autumn and winter production of the next autumn and winter.

Since July, Wuhan Agricultural and Rural Bureau has organized rice, corn, soybean and vegetable experts, with a piece of packaging area, penetrating into the front line, guiding drought resistance and self -rescue, and in -depth guidance of scientific irrigation in the fields, regulating heating with water, defensive high temperature and heat damage. At the same time, focus on controlling control and strict control of diseases and insects.

The first large -scale use of "one tree, one bag"

Zhang Hailei, deputy director of the Garden and Forestry Bureau of Wuhan City, introduced that in order to fight drought resistance and protect the green war, ensure that the safety of urban gardens has a high temperature and drought period, and the minimum loss of forestry resources and forest farmers. A total of 126,000 drought -resistant personnel were dispatched, and about 1.54 million tons of water were used; forestry production invested more than 10,000 drought -resistant personnel, and more than 150,000 acres of drought and green. The phenomenon has no forest fire in the city. This year, for the first time in Wuhan City, "one tree, one bag", "the bags that everyone saw under the street trees, called drip irrigation bags, each bag can be loaded with 10-20 kilograms of water, there is a hole in the bottom, dripping water, dripping water. You can fully absorb water. "Zhang Hailei introduced that this is a low cost, effect, and more water -saving method of watering in the garden department in the practice of drought resistance and greening. Nearly 208,000 are set up. In recent years, newly planted, drought -resistant trees have basically achieved "one tree and one bag".

Not only relying on garden staff to manually water manual watering all night, the garden department also uses scientific and technological power to apply smart irrigation systems in Optics Valley High -tech Avenue and other places to achieve remote watering of plants. Different plants in different regions adopt a variety of methods including waterwheel watering, sunshade nets, and wetting belts to so that they can be poured and poured through. Zhongshan Park, Ziyang Park, etc. also adopt a grid drought resistance method to ensure full coverage of greening. At the same time, the fourth ring line ecological belt and the forestry on both sides of the Yangtze River have been watering and moisturizing in the major forestry projects in recent years. The focus is on this year's new forests to increase the frequency of watering to ensure the survival rate.

Expert: Multiple reasons cause abnormal high temperature

Data show that since plums this year, the average accumulated precipitation of Wuhan City has a total precipitation of 141.7 mm, 46.1%less than the same period of the same year (an average of 263.1 mm per year), of which Jiangxia is 62.6 mm, which is 76%less than the same period of the same year (average 261.1 mm per year on average, 261.1 mm per year, 261.1 mm per year, 261.1 mm per year. ), Medium to severe meteorological drought, other areas are light to moderate meteorological drought. The average temperature in the city is 31.7 ° C, which is 2.8 ° C (average of 28.9 ° C in the same period per year), which is the first place in history.

Since July 7th, Wuhan City, July 9-16 and July 31st-August 23rd, two continuous high temperature processes appeared, and the second process was stronger and wider. After comprehensive judgment, this year's high temperature comprehensive intensity reached the strongest weather record in 1961, of which the average number of high temperature daily reached 36 days, 18.8 days more than the same period of the year.

Tang Renmao, deputy director of the Wuhan Meteorological Bureau, introduced that the extreme maximum temperatures of the five national meteorological stations have been 40.7 ° C (August 18) (August 18) (August 16th, 17th), and Wuhan 39.7 ° C (August 18), respectively. August 18), Huangpi 39.7 ° C (August 18th, 19th), Xinzhou 39.7 ° C (August 19), of which Jiangxia Station broke through the historical extreme value, Wuhan Station was the same as the historical record, and Cai Dian and Huangpi Station were close to the approaching History record.

Why is there an abnormal high temperature? Tang Renmao's analysis said that global warming is a big background, and the subtropical high pressure is abnormal and strong is the most direct and most important reason. In addition, the sunny and less radiation temperature increases. Under the control of heating and high pressure Warm, the air is dry, and it is not easy to form clouds, which makes solar radiation easier to reach the ground. Since the plum, Wuhan has a lot of rain and less rain, which is conducive to the ground temperature increase, resulting in high temperature sustainability and strong intensity. He also believes that the intensity of typhoons near the coast of my country is weak, and the influence is south. It is mainly in the South China Sea and South China. The typhoon landing is significantly less. High temperature weather.

Wuhan has implemented many artificial rainfall operations

The meeting revealed that Wuhan has implemented many artificial rainfall operations. From August 16-17, the meteorological department seized the opportunity to carry out artificial rainfall operations. Among them, the Meteorological Bureau of Huangpi District carried out two smoke stoves to rain, and Jiangxia and Xinzhou District Meteorological 4 innings carried out rocket rainfall operations. On August 17, the Hubei Provincial Meteorological Bureau organized the province to carry out air rainfall operations and successfully operate over Wuhan. The operation area is small to the middle rain, with local heavy rain. Among them, Panlong City in the south of Huangpi, 32 mm of the General Mountain in the eastern part of Xinzhou, and 34 mm in the southern hillside of Jiangxia. Carry out rainbrows.

According to the latest meteorological data analysis, it is expected that the high temperature weather will be further alleviated by the end of August, but the precipitation is still less. Among them, from August 25-28, Wuhan City from the afternoon from the afternoon to the night of multi-sex precipitation, the local rainfall was medium, and the highest temperature was 33-35 ° C; the 29th night-31st day during the day during the day, and the high temperature intensity was weakened. The maximum temperature drops below 33 ° C, and the minimum temperature drops below 25 ° C.

Tang Renmao said that according to the forecast, Wuhan City's autumn flood season (September-October) in the 2022nd (September-October), the total high temperature and rain in most areas were 90-110 mm, which was 1-3 % less than the same period of the same year. The average temperature was 22-23 ° C. 1.3-1.5 ° C higher than the same period of the year.
