Affected by the drought, the iconic hydrological station of Dongting Lake — Chenglingji Station Water was located at 8:00 on August 23 to 22.96 meters, which was the lowest water level in August in the 30th year of the station. Faced with the increasingly severe drought situation, Hunan Province strived to reduce the impact of extreme weather through water storage, scientific water adjustment, and accurate use of water.

Re -pre -judgment: Full of water in advance

As the scorching sun, watching the golden rice waves ups and downs, Huang Hong in Qingrui Village, Huaqiao Town, Hengnan County, Hunan Province took a sigh of relief: "Fortunately, the channel has water. This year's rice is not drought this year. The output is 200 pounds more than last year. "

Hengnan County is located in the "Heng Shao Drought Corridor" in Hunan Province. This year's drought is particularly prominent. Local irrigation water sources are mainly from Ouyanghai Reservoir. Wang Xiaohong, director of Dongzi Ganqu, Hengnan County, Ouyanghai irrigation district, said: "Ouyanghai Reservoir has stored more water in advance. Although the drought in Hengnan County is relatively serious, it is more than 90,000 There are water can be irrigated in the acres of farmland. "

The situation of the Ouyang Sea Irrigation District is a microcosm of Hunan this year through the planning of reservoir water storage and actively preparing for drought resistance. Luo Yijun, the person in charge of the Hunan Provincial Department of Water Resources, told reporters that the meteorological and hydrological departments predict that the rainfall will be less from July this year. Therefore, after mid -June, the Hunan Provincial Department of Water Conservancy planned the water storage work in advance to ensure the safety of flood prevention safety. , Terminal heavy rainfall as the last heavy rain during the flood season for reservoir water storage dispatch.

By the beginning of July, when the rainfall began to be significantly less, the Ouyanghai, Double Brands, Shuifu Temple, Jiubujiang and other reservoirs in the Xiangjiang River Basin, and the Xixi Reservoir in Zijiang Basin was basically full of water. "Dongjiang Reservoir's water level is the highest in the same period in the past 20 years, and the water level of the Tianhe Reservoir is the highest since the construction of the reservoir. These water has now become precious drought resistance resources." Luo Yijun said.

Grab scheduling: scientific water supply to water supply

"The upstream large water is irrigation, and the tight water volume of the downstream" is a long -term problem of some irrigation areas. This year, multiple irrigation districts in Hunan Province proposed "pressing upstream and keeping downstream". Through scientific scheduling, it prevents the waste of upstream water resources and fully protects downstream irrigation water.

As the largest irrigation district in Xiangdong, the Jiudujiang irrigation district implemented the "four water release method" this year, that is, there were investigations before the water release, before the water release, the water release cycle was interval, and the water release effect was followed. Qiu Tieyong, a staff member of Jiubujiang irrigation district, introduced: "We have adjusted the water supply cycle. The wheel irrigation cycles of different dry canal are different to ensure that the water can reach the tail irrigation area smoothly."

It is understood that since the occurrence of drought, Hunan has a chess of chess in the province, and the system dispatch the reservoir to replenish the downstream, and strive to achieve a multi -water use to ensure that the demand for urban and rural residents' living water, ecological water, and agricultural irrigation water has been guaranteed. The water conservancy departments at all levels jointly dispatch large and medium -sized reservoirs are more than 70 towns and more than 40 large and medium -sized irrigation districts to hydrate a total of 2.48 billion cubic meters, ensuring the water demand for more than 20 million people and more than 11 million acres of crops.

Calculate the account: Precisely use good water

Under the hot sun, Xiong Huiyang, the staff of the Hongqi Water Conservancy Engineering Management Station of the Shaoyang Dazhen Irrigation District Management Bureau, carried the measurement tool to calculate the use factor of the paddy field irrigation water. He said: "Master these calculation data, we can calculate the accounts and prepare irrigation water more finely."

Xiong Huiyang introduced that due to the different stages of rice on the amount of water, the amount of water has different requirements, so through on -site calculations, combining soil humidity, you can determine the amount of water demand for each hill field, and then accurately release the water to achieve the effect of "using each drop of water". Essence "According to estimates, the water consumption in the Gaoping branch area in our place decreased by 10 % this year," he said.

Zhang Shuguang, a villager in Wanzou Village, Shuimiao Town, Xinning County, Shaoyang City, planted 1,000 acres of rice this year. He told reporters: "This year's drought, the water is more precious, can calculate the accounts in this way, and the irrigation water is more secure."

The person in charge of the Hunan Provincial Water Conservancy Engineering Administration said that through accurate water -saving, most of the large and medium -sized irrigation areas can be used for more than 25 days, and most of the rural water supply projects of small farmland irrigation projects and more than thousands of people can ensure more than 15 days.
