Drought may be upgraded in the future and Zhejiang will fight against drought for a long time

Hangzhou, 41.6 ℃ yesterday, the hottest in the new history Fenghua, 43.5 ℃ yesterday, equalled the provincial record just set When the extreme hot weather ravages the land of Zhejiang, the drought is also spreading rapidly, and the whole province is thirsty Yesterday, the provincial flood control and Drought Relief Headquarters reported the current drought situation and drought relief work in our province, and analyzed the future drought trend As of August 6, 86 small rivers in the province were cut off, 170 small mountain ponds dried up, and 1.08 million people were affected After December 12, the intensity of high temperature in our province may be gradually weakened, but there are still high temperature weather of 35 ~ 37 ℃, so the situation of drought resistance in our province will be more severe The hottest week in Hangzhou yesterday is still the hottest day in history Zhejiang is the rhythm of breaking a record every day The so-called weather records, in various cities, play with the same drum flower Yesterday at 9:00, high temperature attacked the city and occupied the land At 11:00, Fenghua, Yuyao and Zhenhai led the way to "break 4" As of 16:00 yesterday, the highest temperature of 27 counties (cities and districts) in the whole province exceeded 41 ℃ Most of the southeast coastal areas and parts of southern Zhejiang returned to below 40 ℃ The temperature of the top three is 43.5 ℃ in Fenghua, 42.4 ℃ in Xinchang, 42.2 ℃ in Jiande and Shaoxing, respectively Hangzhou also set a new record for the highest temperature since 1951 at 41.6 ℃ Since July, there have been 11 days of extremely hot weather over 40 ℃ in Hangzhou, 9 days more than the same period in 2003 Yesterday, the air conditioning load of Hangzhou power grid remained high, and the power gap once again exceeded 1 million kilowatts In order to ensure people's daily electricity consumption, Hangzhou's early warning plan for orderly electricity consumption was once again upgraded from level D to level F This weekend, it's still the barbecue rhythm The provincial meteorological station predicted that today, except along the island island, most parts of the province will be 38-40 ℃ and some parts will be 41-42 ℃ Especially today, in southern and eastern Zhejiang, there may be thunderstorms from afternoon to night, but Hangzhou has no share The provincial meteorological station predicted that from the 12th, with the eastward retreat of the subtropical high, the extreme heat will be relieved, but there are still 35-37 ℃ high temperature weather, and some areas may still reach 41-42 ℃ It is said on the Internet that Typhoon No 11, which will relieve the summer heat in Jiangsu, Zhejiang and Shanghai, is still brewing Therefore, the meteorological department is still cautious about the forecast of turning cool at the beginning of next week As of August 6, 86 small rivers, 170 small mountain ponds and 1.08 million people were affected by the drought Among them, 288000 people have difficulty in drinking water, 49000 large livestock have difficulty in drinking water, and 3.85 million mu of crops suffer from drought (2.65 million mu of light drought and 940000 mu of heavy drought) In this year's drought in our province, the evaporation and water demand are rising rapidly, and the precipitation is seriously less Since July, the average evaporation of the whole province has exceeded 200 mm, more than 20% more than that of the whole year Due to the large water demand for irrigation and heatstroke prevention, the water supply in urban and rural areas has repeatedly reached a new high, while the average precipitation of the whole province is only 58 mm, more than 70% less than that of the whole year Crops are affected by drought and lack of water, as well as high temperature Due to high temperature and little rain and no condition for irrigation in some farmland, the soil moisture shortage is serious, which affects the normal growth and development of crops At the same time, due to the continuous high temperature and scorching, even if the irrigation conditions are available, some crops may be severely burned, and the agricultural disaster is serious The spread of drought covers a wide area and is scattered and multi-point 11 cities in the province have suffered from different degrees of drought, but the affected areas are scattered The drought areas are mainly concentrated in mountainous areas, semi mountainous areas and remote islands Some fields without effective irrigation facilities for water conservancy projects, such as reservoirs, suffer relatively serious drought, but no large-scale disaster areas of more than ten thousand mu have emerged People with drinking water difficulties are mainly distributed in rural areas and remote islands that use mountain streams or small mountain ponds for water supply Drinking water is difficult What's the concept? It means that the water supply for each person over 15 days is less than 35 liters per day At present, the water storage rate of the whole province's reservoir and river network is basically the same as that of the whole year, but the water level drops rapidly As of 8:00 yesterday, the water storage capacity of large and medium-sized reservoirs in the province is 23.94 billion cubic meters, with a water storage rate of 74.8% The main water supply reservoirs can generally guarantee normal water supply for more than two months If emergency control measures are taken, the water supply time can be longer But compared with August 1, the water storage decreased by 940 million cubic meters, almost 100 million cubic meters per day However, don't worry, the capacity of Xin'anjiang reservoir accounts for about 50% of the whole province At present, the water level of Xin'anjiang reservoir is 100.8m, with a storage capacity of more than 14 billion cubic meters The assurance rate is still very high The downstream cities, including Hangzhou, generally have no problem in urban water supply In addition, the water level of Taihu Lake is also very stable The urban water supply in Hangjiahu area can be basically guaranteed This year, there is also an obvious feature: the drought resistance capacity of traditional dry areas has improved significantly, and there is no water supply difficulty At the same time, a number of desalination plants have been built in coastal islands In Zhoushan, Xiangshan, Cixi, Wenzhou, Yuhuan, Yueqing, Dongtou and other traditional dry areas, the drought resistance capacity has been greatly improved At present, the water supply is normal, but in 2003, these areas are all in severe drought However, Pan'an and Jinyun have no water reservoir in the county, which is relatively serious At present, both cities are planning to build reservoirs to supply water to the county Trend in the future, the situation of drought resistance will be more severe, and the population with poor drinking water will continue to expand yesterday There are 7 municipal and county governments in the province, including Lishui, Shangyu, Shengzhou, Zhuji, Fenghua, Taishun, Tiantai, etc., which have organized 9 rounds of artificial precipitation increase operations, and precipitation will generally occur in the beneficiary areas after operations According to the statistics of the provincial Office of weather modification, from July 28 to August 9, 32 cities and counties (cities and districts) have organized 115 rounds of artificial rain enhancement operations But in the future, the rain situation in the province is still not optimistic Shanghai authorities predict that there will still be little rain in the next 30 days Even if there are new typhoons, the impact on Jiangsu, Zhejiang and Shanghai will be limited The atmospheric circulation in Zhejiang and Shanghai is similar, so we can refer to the situation in Shanghai Provincial defense index predicted that although the intensity of high temperature may be weakened after 12 days, the drought situation in the province is more severe In the worst case, there may be a summer drought followed by a autumn drought, a autumn drought followed by a winter drought, and a winter drought followed by a spring drought next year This has happened several times in the past decades Next, the general trend of drought in our province, the urban and rural water supply of large and medium-sized reservoirs and areas covered by trans regional and trans basin water diversion projects can be guaranteed However, some small watersheds may be cut off, some mountain ponds and small reservoirs may be dried up, and the agricultural drought will continue to spread, and even point by point disasters may occur At present, it is in the period of vigorous growth of crops, and the water demand is large If we want to ensure the water for farmland irrigation by water diversion from mountain streams, we need to invest a lot of manpower and material resources The contradiction between peak power generation, irrigation and water supply of some large and medium-sized reservoirs will be more prominent In accordance with the principle of "living first, production later, key points and general considerations", measures such as "let electricity supply water" and "let irrigation supply water" need to be taken to ensure the safety of water supply The population with difficulty in drinking water will continue to expand The drinking water project for farmers in mountainous areas, which relies on the water from streams or ponds, may not be available due to the lack of water sources The places and number of people who need to supply and transport water will probably increase dramatically The contradiction of inter regional and inter basin water diversion may be intensified, and it is more difficult to coordinate In addition to the high temperature, water quality deterioration events such as cyanobacteria are likely to occur, which aggravates the shortage of water supply According to preliminary statistics, 1.355 million people have been put into drought relief, 137000 sets of drought relief equipment, 26000 pumping stations, 7400 electromechanical wells, 7000 water trucks and 266 million funds have been invested in the province Drought resistant irrigation of 9.58 million mu times temporarily solved the problem of drinking water for 330000 people and 80000 large livestock Next, the provincial prevention index will take the drought prevention and drought relief work as a concrete action to carry out the party's mass line education and practice activities, conscientiously implement the important instruction spirit of the central and provincial leaders, and strive to do a good job in the current drought prevention and drought relief work based on the "drought resistance and long-term drought resistance" Pay close attention to the weather, master the situation of drought and water supply and demand in time, do a good job in the statistics of drought and disaster, and solve the problems in drought prevention and drought relief in time Based on "long drought resistance", we should be ready for continuous drought resistance Strengthen the coordination of drought resistance, coordinate the water use of upstream and downstream, left and right banks, inter basin and inter regional water diversion, reasonably distribute the water volume, gradually reduce the water use for hydropower generation, and strictly control the pure power generation waste water Organize the water shortage areas to take measures such as emergency well drilling, construction of emergency water diversion and supply project, desalination of seawater, artificial precipitation increase, etc., and make every effort to increase the emergency water source We will continue to dispatch working groups on drought control, led by leaders and attended by relevant professional and technical personnel, to key dry areas to guide and assist them in their work Drought relief measures in Hangzhou: at present, there are 53% drought areas above medium level in Hangzhou (12% of which are serious drought areas), 1.147 million mu drought areas of agricultural and forestry crops, 58000 people are faced with drinking water difficulties in varying degrees, and the drought situation has the trend of further expansion and aggravation Hangzhou flood control and drought relief headquarters decided that at 16 o'clock yesterday, Hangzhou city launched a class III emergency response to drought As of yesterday, high temperature and drought have caused agricultural losses of 640 million yuan in Hangzhou Hangzhou has allocated nearly 1 million yuan to purchase more than 500 emergency water pumps for drought relief, which will be distributed free of charge to the severely affected farmers, village collective economic cooperation organizations and farmers' professional cooperatives Among them, more than 4.8 million yuan has been invested in the construction of power supply lines, the laying of drinking water pipes and the construction of drought resistant channels at the two levels of Taihuyuan town and village in Lin'an, while actively implementing the financial subsidies of the superior agricultural departments for the purchase of drought resistant agricultural machinery Lishui: tea farmers are carrying out self-help This is the peak season of tea picking in summer and autumn In the tea garden of ten thousand mu in Xinxing Town, Songyang County, Lishui, many tea prices have curled and withered, falling at a touch In the face of the drought, tea farmers say that not only will tea production be cut by more than half this summer and autumn, but also tea production next year will be directly affected by the sunburn of tea trees The economic loss is incalculable Tea farmers are carrying out various self-help measures, using equipment such as spray and drip irrigation and electric pumps for irrigation, and village cadres are also actively organizing villagers to conduct water diversion irrigation Jinhua: send the high temperature warning message Jinhua City Flood and drought prevention headquarters formulated the Jinhua City drought prevention emergency plan, which has started level IV at present The city has invested 127000 people in drought relief services, 30.28 million yuan in drought relief funds, and 1491 machine hole wells have been used to solve the problem of drinking water for tens of thousands of people in mountainous areas As of August 7, the affected area of crops in the city is 794100 mu, the disaster area is 370700 mu, the total area is 70100 mu, and the direct economic loss is 318 million yuan Since July, Jinhua meteorological station has issued 17 high temperature warning signals, which are sent to key users of various departments and industries through SMS At present, Jinhua meteorological bureau is communicating and coordinating with communication operators to strive for more people to be covered by SMS when major meteorological disasters come Ningbo: emergency water supply pipeline is laid According to Ningbo flood and drought prevention headquarters, 28.3% of the city has been built
