The drought at the end of June, the development of local development in the middle of July, and the rapid spread of the end of July to late August ...

After the flood this year, the rainfall in Hubei province has continued to be less. Since July 7th, Hubei has encountered the worst drought and high temperature and harsh climate since 1961.

Drought resistance and harvest! The province's water conservancy department planned early, carefully dispatch, comprehensively applied policies, and accurately exerted its efforts to ensure water supply and water supply, fully protect the Qiu grain to stabilize the production of irrigation, and achieve staged results in drought resistance. At present, the water conservancy systems in all parts of the province are at the beginning, and do their best to do drought resistance.

Water storage and water reservation to the bottom

5006 reservoirs have 100 million cubic meters daily water

Through the channel, the clear water flows to the field ... On September 14, the Zhanghe Reservoir opened the third round of agricultural irrigation to meet the needs of rapeseed and wheat sowing irrigation in the Zhanghe Sanqian canal irrigation area. Wanlian meter.

In normal years, Zhanghe Reservoir generally irrigated two phases, mainly serving rice growth. In September, although the weather in the Zhanghe River Basin and the irrigation area turned cold, it did not have effective precipitation, and the drought in the irrigation area continued to develop. After the rice harvest of rice, rapeseed and wheat sowing will be ushered immediately. The Zhanghe Reservoir will go all out to actively carry out the third round of irrigation.

According to reports, from May 16th to the present, the Zhanghe Reservoir has accumulated a total of 152.11 million cubic meters of water and 1.83 million mu of farmland.

The sufficient water source is the confidence of drought resistance. Before the flood this year, the Provincial Water Resources Department guided the local area to seize the opportunity of rainfall in March and April according to the medium- and long -term forecasts.

According to the Provincial Water Resources Department's reservoir, there are 5006 reservoirs in the province's peak periods of water and irrigation, and the daily water supply is 100 million cubic meters. Since the beginning of this year, a total of nearly 6 billion cubic meters of irrigation water has been irrigated.

In addition to storage and water storage in advance, the province's water conservancy supplement shortcomings also provide solid support for drought resistance.

Since 2021, the Provincial Water Resources Department has actively promoted the completion and acceptance of more than 3,000 reservoirs, and was completed at the end of June this year. A total of 2.5 billion cubic meters of Xingli Rong Rong was restored to effectively ensure water supply safety and food safety.

"The water level is raised by 0.5 meters, and the storage capacity of the reservoir has increased by 4 million cubic meters." According to the relevant person in charge of Anlu Jiefang Landscape Reservoir, after the completion of the main project in May this year A total of 18 million cubic meters of water supply have benefited nearly 100,000 acres of farmland in the irrigation district.

After entering September, the drought in the Yangtze River Basin continued to develop, forming a summer and autumn drought, the water level in the Yangtze River fell below the record and continued to decline. On the one hand, it seized all the timing of water storage and water.

At the junction of Hong'an County, Macheng City and Xinzhou District, Wuhan City, due to scientific management, water conservation, scheduling with water, and providing plenty of irrigation water for more than two months. At present, there are still more than 59.60 million cubic meters The amount of water exceeds half of the total library capacity.

Nowadays, when you need to use water in the next reaches, you must declare it first. Use immediately, close the sluice immediately after use, and never waste a drop of water.

Seize the timing to quote the water

851 culvert pumping station grab the rivers and rivers

10 pipelines with a caliber of 300 mm are pierced into the Yangtze River, and the other end connects the Ma'anshan of Jiayu Sanhu Lianjiang Reservoir into the flood gate. With a 700 -meter -long pipeline, the Yangtze River water flows into the reservoir.

In order to resist drought and harvest and protect people's livelihood, Jiayu launched six Yangtze River water lifting projects. The Sanhu Lianjiang River Yinjiang Reverandry Reservoir Project is one of them. Meter.

Sanhu Lianjiang Reservoir is the backbone project of farmland of Jiayu County. The beneficiary area of ​​300,000 mu has been beneficial. Since the water leaving water, the water level of the reservoir has dropped from 27.5 meters to 26 meters. The local plan to replenish the water level of the Sanhu Lianjiang Reservoir by nearly 27 meters through the nearly two months, providing support for continuous drought resistance.

Facing the drought, throughout the province, through the gates and pumping stations, they tried to attract the pumping of the Yangtze River and the Han River to "quench thirst" for farmland.

Miaotou pumping station is a drainage and drought resistance hub project in Hannan District, Hanchuan City. It is responsible for 7 township drainage and drought resistance. Due to the low water level of the Hanjiang River, pumping stations cannot take water operations, and 300,000 acres of farmland are "thirsty." On August 10, the Hanchuan Water Conservancy Department quickly organized machinery and Labor to build a dam pier machine in the templetout head of the Hanchuan section of the Hanjiang River.

In Duoxiang Town, Tianmen City, the channels along the irrigation are almost dry. On August 11, Tianmen City Water Conservancy and Lakes organized a special class to set up a temporary pump motor at the Liujiahe pumping station rack at the Han River to reinforce drought resistance in the eastern area of ​​Tianmen.

On August 23, at the martial arts gate, the pumping pump was open, and the river was continuously pumped into the embankment. Jiang Shui passed the current out of the Guanqiao Port of Wudukue, and stretched a few kilometers to reach the irrigation district around Wushan Lake to ease the drought conditions of 17 administrative villages in the surrounding 6 towns.

Zaoyang is a large city in Hubei, and northern Hubei is a "dry bun", and its resource deficiency is serious. As early as June this year, Zaoyang City launched the two major pump stations in Dagangpo and Shitai Temple. "By attracting guests, intercepting river water, developing spring water, increasing rainwater, and excavating groundwater, water storage water and water and water and water." Jingmen City Water Conservancy and Lake Bureau said that they did their best to reduce the effects of drought.

The reporter learned from the Provincial Department of Water Resources that at the peak of water, there were 111 culverts and 740 pump stations in the province to attract the rivers of the outer rivers. Among them, the Yangtze River has 11 culverts, with a daily water volume of 12.43 million cubic meters, and 34 gates stations in the Han River. From July 10th to September 19th, the main gates of the Yangtze River and the Hanjiang River had a total of 2.505 billion cubic meters.

Full load adjustment

Two major projects have the power to resist drought

On September 9th, according to the instructions of the Provincial Water Resources Department, the five units of the Jiangji Han project were simultaneously operated to run emergency water adjustment to ensure water demand for the lower reaches of the Han River, around the long lake and the Dongjing River basin.

In this year's struggle with the dry demon, the leading project of the Jiangji and Hubei Water Resources Allocation Project fully played the role of the water conservancy project, scientifically regulated water, and showed great power.

After our province was provinced, the weather continued to be sunny. According to the unified dispatch of the Provincial Department of Water Resources, the process of led the river to increase the flow of traffic and "quench thirst" for the lower reaches of the Han River, Long Lake and Dongjing River Basin. On August 8, the project increased traffic. By 410 cubic meters per second, the super design flow runs, sending Ganlin to the lower reaches of the Han River.

Long Lake is located at the junction of Jingzhou, Jingmen, and Qianjiang. It guarantees the irrigation water sources of more than 4 million acres of arable land along the line and 800,000 people along the Dongjing River live water supply. How to make the "water basin" more water in the long lake has always been the focus of drought -resistant and scheduling this year.

In the "window period" of the Danjiangkou Reservoir to increase the flow of lower leakage and the rising water level in the middle and lower reaches of the Hanjiang River, starting from 17:00 on August 22, the Provincial Water Resources Department dispatched the Jiangji Han Dynasty project to pick up the flood gates of the river. Drought in the middle and lower parts of the four lakes.

On August 12, there was a shortage of water supply in Huangjiakou Town and Wanquan Town, Huangjiakou Town and Wanquan Town. The water source came from the Dongjing River. After emergency scheduling, the Yangtze River water was injected into the long lake, and then the Dongjing River was supplemented. Solve the difficulty of living water along the Dongjing River.

The northern Hubei water resource allocation project is a major livelihood project with a wide range of people's livelihood in our province. It was just built last year. In the process of drought resistance this year, it fulfilled the efficiency of engineering.

In order to alleviate the drought in northern Hubei, the North Hubei project has continued to adjust the water from Danjiangkou Reservoir to Xiangyang, Suizhou, Xiaogan and other places since the first start of water and drought resistance on June 21, providing effective guarantee for the rural people drinking water and farmland irrigation along the line.

As of 7 o'clock on September 19th, the Jiangji and Han project cumulatively attracted 3.479 billion cubic meters of the Yangtze River water, of which 384 million cubic meters were replenished to Changhu and replenished 3.028 billion cubic meters to the Hanjiang River. For 100 million cubic meters, irrigated farmland area of ​​920,000 acres, and a livelihood of 775,000 water supply.

Hubei drought resistance also touched the heart of the Ministry of Water Resources. In order to ensure the demand for irrigation water for the growth of large livestock water and autumn grain crops, the Yangtze River Commission issued a dispatch order. From September 14th, the traffic traffic increased from September 14 to 9,000 cubic meters per day per day per day. second. Under the dual guarantee of artificial rainfall and water conservancy scheduling, our province has effectively alleviated the rapid decline in dry flow water levels in the middle and lower reaches of the Yangtze River, ensuring water demand for 356 large and medium -sized irrigation areas and a large number of small irrigation areas.

Do not rely on Dragon King to rely on technology

1577 sites artificially lower Ganlin

On August 24th, with the deafening roar, two rainfall rockets rushed from the artificial rain increase operation point of Muyu Town, Shennongjia Forest District. A timely rain, according to the observation of precipitation of more than 15 mm.

On the same day, the artificial rainfall operation site in Tongshan County was full of people. In conjunction with a rocket launch device with an emergency scheduling of the Hubei Provincial Meteorological Bureau, the local artificial rain increase team was treated and paid close attention to the weather. According to the relevant person in charge of the Tongshan County Meteorological Bureau, the favorable conditions of artificial rain increase operations sometimes appear in the middle of the night or even early morning. The manual rainfall team needs to wait for the pillow and wait for the 24 hours in key areas.

In September, Hubei will still maintain a trend of high temperature and rainy weather. It is expected that the province's precipitation will be 10 to 40 % less than the same period, and the average temperature is 1 ° C to 2 ° C higher than the same period of the year. On August 23, the Hubei Provincial Meteorological Bureau launched an emergency response to the fourth level of meteorological drought. Earlier, from August 15th, the Provincial Meteorological Bureau implemented a coordinated manual rainfall operation. In order to solve the demand for drinking water, industrial and agricultural production and ecological water in the drought area, the Baoqiu grain harvest provided a solid guarantee. At Xiangyang Liuji Airport, two high -performance artificial rainfall operating planes are standing at any time. 159 high guns, 220 rockets and 26 sets of ground smoke furnaces are deployed in the province. Essence Meteorological departments at all levels pay attention to weather changes in real time, and capture the timing of manual rainfall operations. After triad to seize the opportunity, after artificial rain increase operation, as of the end of August, there were 1577 stations in Shiyan, Xiangyang, Shennongjia, Yichang and other places. The single site exceeds 50 mm, and the rainfall of 6 stations reaches more than 100 mm. On August 25, on the basis of issued 50 million yuan of disaster relief funds in the early stage, the Provincial Department of Finance once again allocated 182 million yuan in drought resistance and relief funds to support Enshi, Shiyan and Yichang. , Add a variety of drought resistance and mitigation measures such as "one spray and more promotion" and fertilizer and water regulation of autumn grain crops.

The main person in charge of the Provincial Department of Water Resources said that the responsibility for drought resistance is more important than Taishan. At present and in the future, there is still no obvious rainfall process in the province. It is necessary to fully prepare for the anti -drought, long drought, winter and spring drought, and closely monitor the changes in the weather, find out the water storage of water and lakes in the river, accurate objects, accurate scope, accurate policy, and dispatch water conservancy projects. , To satisfy human and animal drinking water, irrigation water, and shipping water, and resolutely win this drought -resistant defense war.
