Based on the anti -drought and long drought -Hunan scientific response to the drought demon

On September 19th, Zhenghe Farm, Daoxian County, the villagers' spray and irrigation leader in managing vegetable fields. Recently, the county has encountered high temperature and rainy weather, and the agricultural bases have increased the construction of irrigation infrastructure, using drip irrigation, spray irrigation and other methods to irrigate crops to minimize losses caused by drought.

"Out of the water, the water is out of the water." On September 19, Qinfeng Village, Shijiachong Street, Jishou City, successfully made a machine well, about 200 tons of water per day, which can solve the safety of more than 500 people drinking water.

Since July 8th, the province has continued to be sunny and hot, and the drought has continued to develop and spread. At present, the drought in summer and autumn has become a set. Faced with the increasingly decreased water conservancy project, drought gradually increased, our province went all out to find large -scale water conservancy projects, to find water sources, and to carry out water and diversion, etc., scientifically cope with droughts, and minimized drought losses.

Precise scheduling, timely water storage and hydration

On September 12, the Ministry of Water Resources once again launched a special operation of the "Joint Disclosure of Drought and Water Supply for Drought Protection of the Yangtze River Basin Reservoir Group". Our province actively cooperates with the Sanxia Reservoir to jointly dispatch the backstream large -scale reservoir to accurately hydrate downstream, with an average daily hydration of 50 million cubic meters to meet the needs of the river ecology, the living of residents along the line, and the water supply enterprise.

Under the high temperature of the heat, the amount of water and evaporation of life in the province increased significantly. During the peak period, water consumption was more than 350 million cubic meters per day. Nevertheless, according to the current operation method, except for Ouyanghai, Shuifu Temple, Jiubu River, and Guanzhuang in the Xiangjiang River Basin, the six streams and Huangshi reservoirs of the Lishui Basin can be maintained in 50 days, and the remaining large reservoirs can be maintained until it can be maintained until it can be maintained to At the end of November.

Reserve drought -resistant water sources in advance. In early July, the Provincial Water Resources Department seized the tail of the rainy season and accurately dispatching major reservoirs to stop the tail flood. The large -scale reservoirs such as Ouyanghai, Shuangpai, Shuifu Temple, Jiubujiang and other large reservoirs in the Xiangjiang River Basin are “full of a lot”. Highest. On July 8th, the province's various types of water conservancy projects storage of 38.66 billion cubic meters, which was 8%over the same period.

The reservoir has water and does not panic. At present, the amount of irrigation water in various types of irrigation areas in the province is 9.06 billion cubic meters of irrigation water, consumes 75 million cubic meters per day, and can keep the area of ​​late rice irrigation 19.1 million mu.

Find the well to find water, the variable memory is incremental

"There is an abandoned pit in Meta Village, Yuyu Ping Town, which is a source of water resistance to drought emergency reserve. The water storage capacity is nearly 2 million cubic meters. It is expected to irrigate nearly 10,000 acres of farmland." At the beginning of September, the water conservancy bureau in Yuelu District, Changsha City locks the water source. Action quickly. Use 5 large -power water pumps to operate day and night, which can supply 120,000 tons a day, which is equivalent to the water volume of a small second reservoir.

Continuous droughts have gradually decreased on surface water, and it is imminent to find new water sources. Our province adopts well -bearing and finding a cave water, underground rivers and other measures to open up new water sources.

Water conservancy and other departments have converted the existing groundwater monitoring wells into water supply wells, and the amount of drought -resistant water sources is increasing. The province's existing groundwater monitoring well is 306, of which 100 monitoring wells can be provided. At present, the 4 monitoring wells in Shimen County and Hetang District have begun to supply water, ensuring more than 500 people's lives and irrigation water for 1,000 acres of farmland.

Increase water. Since August, local governments have fully tapped the potential of groundwater through drought resistance. The Provincial Geological Academy and the 15 ground survey units affiliated to the work of drought resistance to find water and find water to provide technical support for drought resistance. At present, the province has accumulated more than 3,700 wells, increasing more than 44 million cubic meters of water.

Scientifically divert water, "water nest" solves thirst

The high temperature and high temperature and rainy weather caused the water level of the "water nest" of Dongting Lake to continue to decline and the water surface decreased, and it began to "thirst".

On September 19, the reporter came to the first phase of the hydration project in Dongting Hubei. He saw a large drain pipe deeply tied in the Yangtze River, and the water from the Yangtze River continued to flow into the surrounding farmland through the canal.

Taking the dry flow of the Yangtze River, Songyu Water, and Caowei River as the source of water, jointly dispatching the northern region's hydration project for hydration. Since the drought this year, the segmentation and hydration projects in Dongting Hubei have given full play to the water replenishment efficiency. The cumulative hydration exceeds 600 million cubic meters, and the maximum daily hydration volume is 16.62 million cubic meters, which effectively relieves the water use of drought.

Facing the drought brought by the low -history low water level, Dongting Lake District relieves the drought through the water diversion of the river, the water to the water, the water reservation of the inner lake, and the northern replenishment of the northern part. During the drought, Dongting Lake District invested over 100,000 mobile pumps, with more than 1,400 wells, and a total of more than 700 million cubic meters of water lifting the water level. At present, the Dongting Lake District has carried out 1,515 water raises above the second level, and the daily water is about 4.2 million cubic meters, which directly solves the problem that cannot be taken from the water.
