After boiling the hot summer, but did not wait for Mianmian Autumn Rain, how can Hunan cope with the next drought?

Guide

High temperature and rain, I believe this is the first impression of many people this summer.

I thought it would usher in a hot summer day. However, people are not waiting for Gan Lin, who have long desire, but also high temperature and drought for the day.

On September 19, the Provincial Meteorological Observatory released the weather forecast. It is expected that the rainfall in the next ten days is less, and most areas are mainly cloudy weather in sunny days.

A few days ago, the provincial drought -proof and drought -resistant work class reminded that it is necessary to prepare for "summer, autumn and winter drought".

What is the drought facing in our province? How to deal with it?

status quo

The editor learned from the Provincial Department of Water Resources that at present, the water storage of the project is increasingly decreasing, the drought has gradually increased, and the area and scope of the area are gradually expanding.

The overall judgment is that this year's drought is very serious, the drought is basically controllable, and the future situation is severe.

Why is it here?

Less precipitation is one of the main reasons. Since this year (8:00 on January 1, 2022 to 8:00 on September 19), the province's cumulative precipitation has a total precipitation of 1175.3 mm, and the average of 1204.4 mm in the same period of many years is 2.4%. Since the flood in the flood (8:00 on April 1, 2022 to 8:00 on September 19th), the province's cumulative precipitation has a total precipitation of 812.0 mm, and the average of 924.7 mm in the same period of many years is 12.2%.

Another important reason is that the continuous high temperature weather leads to an increase in evaporation. According to statistics from the 47 surface evaporation stations in the province, the average daily daily water surface evaporation volume in the province in August was 4.9 mm, and the average value of the same period of many years was 34%.

These factors lead to low water levels in the river and lakes, and the water volume is small. About 10 % of the province's water level is close to or lower than the lowest water level in history. The dry streams of Xiang, Zi, 沅, and 澧 澧 are mainly controlled by 0.26 meters to 2.72 meters for many years. Essence The water volume of Dongting Lake has been less than 60 % since July, and the flow of the lake on the 19th is nearly 80 %.

In addition, the main large reservoir has less water storage and the groundwater level continues to decline ... These have brought certain challenges to the mass production of the masses.

How to keep the bottom line of drinking water, stabilize food production, and minimize the impact of drought on production and life? Become a must -answer in front of Hunan.

Respond

Faced with the rare and high -temperature weather in history, all departments at all levels in the province quickly acted, made a lot of efforts, and made a lot of efforts.

At present, various types of water conservancy projects in the province are 27.98 billion cubic meters of water, and the amount of available water can be 16 billion cubic meters; water lifting and water and water is 4 billion cubic meters, and 3,600 wells are used. Late rice irrigation water demand.

It is estimated that by the beginning of October, the irrigation of farmland in the province can basically be lifted, and the harvest of autumn grains is expected.

Those who want to win up and down. The Provincial Party Committee and Provincial Government attaches great importance to drought -resistant and drought -resistant work, set up special classes for drought -proof and drought -resistant work, and organize and guide the province's drought -proof and drought -resistant work. In accordance with the requirements of the provincial party committee and provincial government at all levels, in accordance with the requirements of the provincial party committee and provincial government, they adhere to the "water" as the core, start and improve the emergency response in a timely manner, consolidate work together, and go all out to fight drought and disaster.

Persevere water storage water and water, precise pipe water for water. According to the editor's understanding, the Provincial Water Resources Department, in accordance with the overall idea of ​​a multi -purpose water, overall planning, and classification, cooperates with the joint dispatching of the three -water river basin large reservoir in the Three Gorges Reservoir to accurately hydrate the downstream, with an average daily hydration of 50 million cubic meters to meet the river ecology of the river to meet the river ecology. , Demand for water consumption and power supply companies along the line.

At the same time, comprehensively implement the "Thousands of Water Conservancy Cadres to the Field" action, and send 9400 batches of 53,000 passengers to accurately dock the irrigation area and rural water supply projects, calculate water accounts and long water flow, allocate water resources to help solve the problem of over 6800 supplies of insurance and insurance supply more than 6800 This; the launch of the irrigation district cadres and employees invested more than 250,000, and carried out the dredging of obstacles and water for the irrigation area channels.

Relevant departments have also moved in action, and they took multiple measures to open up water sources to make full use of groundwater resources, and the variable stock was incremental.

The natural resources, ecological environment, water conservancy and other departments have converted the existing groundwater monitoring wells to water supply wells, and the amount of drought -resistant water sources is incremental. The province's existing groundwater monitoring well is 306, of which 100 monitoring wells can be provided.

The Provincial Geological Institute has carried out field work at 14 exploration sites. At present, it has become 21. The amount of water mining has reached 1984.64 cubic meters a day, which can solve the problem of 8021 people.

The Provincial Department of Housing and Construction organized a survey and evaluation of urban water supply safety and standardized, and dispatched 184 cities in the province to ensure the safety of water for urban residents.

Water is inseparable from power protection. State Grid Hunan Electric Power opened the "green channel" of drought resistance in time, sent electricity to the fields to ensure agricultural drought resistance. According to statistics, since July, more than 30,000 electric vehicles have been dispatched and more than 80,000 electricity personnel have been dispatched. More than 200 inspection equipment such as infrared temperature measurement, drone, and other inspection equipment are used. , Pumping station, power stations and lines to inspect the scarcity.

In the face of drought, we must learn about open source pumping water, but also learn from science and technology to improve the ability of crops to resist drought and reduce water consumption.

On August 25, the thousand acres of kiwi bases in Zhulian Village, the Miao Autonomous County of Chengbu, Yang Xiaoshu, the person in charge, was inspected the operation of the control system of the water and fertilizer.

The Agricultural and Rural Bureau of the Lengshui Beach District of Yongzhou City guides farmers to irrigate the temperature, reduce high temperature heat damage, enhance the capacity of crop resistance, and apply fertilizer to supplement crop nutrients.

The Puyang Forestry Bureau instructed the growers to use the methods of covering moisturizing and properly trimming branches to reduce moisture evaporation, which greatly improved the effectiveness of drought resistance, and the drought resistance area of ​​the camellia forest reached more than 70%.

According to the different requirements of the amount of water at different growth stages of rice, the Dazhen Irrigation District of Shaoyang City combines soil humidity to calculate the use coefficient of rice field irrigation water to determine the amount of water demand for each hill field, to achieve precise water release, and fully "make good use of each one. Drip water.

What should I do if I do after the prevention and treatment of drought? The technical personnel of the Agricultural and Rural Bureau of Hanshou County regularly extract pest samples in the fields to help everyone prevent control through scientific means.

It is understood that the Provincial Department of Agriculture and Rural Affairs has organized 8 agricultural technical expert service teams, which are responsible for the guidance of agricultural drought resistance and relief technology in 14 cities and states in the province. The agricultural and rural departments at all levels in the province have dispatched more than 3,300 technical service teams to the fields to go to the field, penetrate the front line of agricultural production, and provide farmers with drought resistance and relief technical guidance services.

On the afternoon of September 17, Mao Weiming, deputy secretary of the Provincial Party Committee and Governor Mao Weiming, went to the provincial drought -proof and drought -resistant work class to investigate, clearly required, fully recognized the severe situation, and made every effort to resist drought, drought drought, and disaster. , Make every effort to protect water, harvest in harvest, and protect people's livelihood. Fully achieve the "three guarantees", that is, to ensure the safety of life, production, and ecological water when it encounters medium drought, to ensure that during severe drought, living water is basically guaranteed, ensuring the harvest of food, and minimizing drought loss.

Xiaobian believes that as long as we make long -term preparations and go all out, we will definitely be able to win the tough battle of drought resistance and disaster reduction.

In addition, sharing a good news, from the 20th, will continue to penetrate from cold air to south. By the 23rd, the temperature will drop by about 10 ° C, and the high temperature will soon be lifted.
