For three consecutive years of drought, Yunnan has been thirsty. As of the end of January, a total of 33 meteorological monitoring stations in the province had meteorological droughts of varying degrees, 2.35 million mu of crops were affected by drought, and 1.441 million people and 827,000 head of livestock had difficulty drinking water. Please see the reporter’s report from the frontline of the drought.
On February 8, the reporter learned from the Yunnan Flood Control and Drought Relief Headquarters that severe drought, which is still continuing to develop, has caused 2.35 million mu of crops in Yunnan drought, and 1.441 million people and 827,000 head of livestock have difficulty drinking water.
Due to the abnormal climate, continuous shortage of water flowing from rivers and rivers, and serious shortage of water in reservoirs and reservoirs, the drought-resistant and water-supply situation in parts of Yunnan before the arrival of the rainy season this year is not optimistic.
Drought persists and meteorological drought occurs at 33 meteorological stations
“This year's Xiaochun has basically lost its harvest.†Wang Fa, the party secretary of Fuyang Street, Yuming County, Kunming City, said, “In a normal year, wheat should be heading for flowers, but you see, this grows to twenty or thirty. cm."
The reporter saw that a large area of ​​arable land in the Luan Village, which is located in the Mid-levels, was cracked and the wheat, broad bean and other crops generally did not last long or died in the fields.
"The water output from the village's Longtan was only 1/3 of the previous year. It was difficult for more than 400 people from two villagers groups to drink water," said Wang Fa. "Since December last year, we have used a pump to pump water to them."
Similar droughts also occurred in many places in Yunnan. There are 8 natural villages in Pingyao District, Luyi District, Shilin Autonomous County, where there are currently no effective water points and drinking water for humans and animals is difficult. A villager from Xiaoguanzhuang said that the water supply in the village has been provided by Xiaotun Reservoir. Since the drought is serious this year, about 5,000 people relying on the water supply of the Xiaotun Reservoir have already used water urgently, and now they rely mainly on the street offices and the village committee to regularly pull water. supply.
In Quzhong, Qujing, as of February 6th, 48 rivers had been cut off, an increase of 6 from the previous week; 74 reservoirs had dried up, five more than the previous week; electromechanical wells had less than 83 eyes, which was more than the previous week. 5 eyes. The water storage capacity of the reservoir in the city's reservoir was reduced by 45% over the same period of the past several years.
The total amount of water stored in the Honghe Hani and Yi Autonomous Prefecture in southern Anhui is currently only about 370 million cubic meters, accounting for 51.13% of the planned water storage capacity. The drought-stricken area of ​​crops in Quanzhou exceeded 100 million mu, and direct economic losses due to drought amounted to 593 million yuan.
According to statistics from the Yunnan Flood Control and Drought Relief Headquarters, the average precipitation in Yunnan Province since the end of the last year was only 51.7 millimeters, which is 20.8 millimeters less than the same period in the same period and 29% less. In January of this year, the river average water supply in the province was 31% less than the average. As of the end of January, a total of 33 meteorological monitoring stations in the province had meteorological droughts of varying degrees, 2.35 million mu of crops were affected by drought, and 1.441 million people and 827,000 head of livestock had difficulty drinking water.
The water in the city is tense, water restrictions in Kunming, Qujing, etc.
The lack of water caused by drought and rain caused inconvenience to the production and life of the people.
"Beginning in late February, Kunming will adopt measures with advance notice, plans, and time-limited water supply in the zoning area. According to the development of drought, based on the protection of basic domestic water, the water pressure of the city's water supply will be adjusted in a timely manner, and water supply will be appropriately reduced. The city water supply is safe," said Wang Daoxing, deputy mayor of Kunming.
It is understood that as of February 4th, Yunlong, Songhuaba, Baoxianghe, Dahe, Chaihe and Sweiweicun Reservoirs, which are the water sources for Kunming's urban water supply, have only 132 million cubic meters of water, which is 57% less than the same period of last year.
According to estimates, from the 4th of February to the 31st of May this year, after Kunming took water saving measures to save 50,000 cubic meters of water per day, the city’s daily average water demand was 900,000 cubic meters, and the total water supply demand was 106.2 million cubic meters. The actual water availability of the Songhuaba Reservoir is only 73.17 million cubic meters, and the raw water gap is as high as 33.03 million cubic meters. Taking into account the water supply during the project period and the emergency water supply project, the raw water gap still has 1.21 million cubic meters.
Even if the rainy season comes normally this year, runoff will not be able to form until the end of June. Therefore, the original water supply after the end of May is still uncertain, and the water quality of the water supply reservoir in the city is low, and the quality of the factory water quality is not up to the standard. Urban production and life The situation of water security is severe.
According to the reporter’s understanding, Qujing, Yunnan’s second-largest city, proposed to provide water for all cities and towns in the urban water supply program from September 1st to June 30th last year. Industrial water use, and the implementation of stepped water prices, vigorously promote the reuse of water and other recycling water measures.
As of the end of 2011, 216 of the high-water-consuming enterprises such as bathing centers and car-washing plants had been closed in the central city of Qilin City, and the water consumption plan for residents in the downtown of Qilin City had been reduced from 120 liters per person per day to 80 liters.
Use advanced geophysical equipment to find groundwater and ensure drinking water safety
Severe drought caused the Yunnan Provincial Party Committee and the provincial government to attach great importance to the provincial party committee secretary Qin Guangrong, acting governor Li Jiheng and other provincial leaders to carry out special research and in-depth investigation and guidance drought drought drought disaster work.
The Department of Water Resources of the Provincial Department of Water Resources will use water supply to May 31 as the time limit, starting from the balance analysis of water supply and demand, urge local governments to formulate urban and rural water supply plans based on the existing drought-resistant water sources, clarify the urban and rural water supply safety responsibilities, and refine and implement emergency water supply measures.
Recently, experts used the world’s leading geophysical equipment to find groundwater for the first time in Yunnan. These devices can detect geological conditions from 100 meters to 2000 meters underground and help determine the location of wells.
At present, the Yunnan Provincial Department of Land and Resources has organized 79 sets of drilling rigs to carry out underground water search, construction of 79 deep wells, more than 20 wells have been accepted, and the amount of sunrise water is more than 6,300 cubic meters, which has eased drinking water problems for about 85,000 people.
The counties and counties that were affected by the drought also took active action. The Guandu District of Kunming City allocated 500,000 yuan to build a fixed rainfall increase operation point and a mobile rainfall increase operation point. At the same time, guide farmers to adjust the structure of agricultural planting, mainly for the cultivation of barley and other drought-resistant crops. In Wuhua District, Kunming City, through the improvement of the use rate of recycled water, water conservation, good drought protection and water supply work, and actively promoting the reuse and treatment of sewage in the area.
Da Yao County in Chuxiong Qiang Autonomous Prefecture is the old dry area in central Guizhou. Since the beginning of this year, Dayao County has implemented a responsibility system for administrative heads of reservoirs for impounding reservoirs, and has adopted various measures such as storage, introduction, extraction, and pull-in according to local conditions to actively increase the water resources for drought relief.
Relevant departments predict that there is a high possibility of large-scale severe drought
Since 2009, Yunnan has experienced severe drought for three consecutive years. Experts from the Yunnan Meteorological Bureau explained that during the three years, the precipitation in the rainy season in Yunnan was relatively small, resulting in the continuous development of meteorological drought. The main cause is the continuous abnormality of the summer monsoon that affects Yunnan, the decrease of water vapor transported to Yunnan, and the decrease of the low-value convergence system formed by the monsoon, resulting in weak convection over Yunnan, and the location of the western Pacific subtropical high is also unfavorable for precipitation in Yunnan.
After mid-January of this year, the fluctuation of the south branch trough turned into a weak state, which is not conducive to the transport of warm and wet air in the southwest. Under the control of dry and warm westerly winds, most of Yunnan continued to be sunny without precipitation. In addition, the high temperature and evaporation during the same period made the recent meteorological drought in Yunnan develop rapidly.
According to the comparative analysis made by the Yunnan Meteorological Bureau, due to the low rainfall in the past three years and the lack of water storage in the reservoir, the situation of the reservoir in the reservoirs in the central and eastern parts of Hebei Province is even more severe, and the degree of drought will increase. According to the weather forecast, in early February, except for cloudy or local rain in parts of eastern Yunnan and parts of northwestern Yunnan, most areas in Yunnan still maintain clear and cloudy weather.
The meteorological and hydrological departments analyze and predict that Yunnan is in a high-frequency period of drought. It is more likely that a large-scale severe drought will occur in the next period.
It is understood that this month, the Yunnan small spring crop will gradually enter the critical period of water demand and low temperature sensitive period, combined with farming and weather, meteorologists recommend that all localities should continue to pay close attention to the development trend of drought, pay attention to saving water and drought.
According to reports, the meteorological department of Yunnan Province has further strengthened its analysis and assessment of drought conditions and soil moisture monitoring. The units at all levels of the province's artificially affected weather units are waiting in a row and will take advantage of the opportunity to actively carry out artificial rainfall enhancement operations to increase the reservoir capacity. Water and reservoir come in water.
On February 8, the reporter learned from the Yunnan Flood Control and Drought Relief Headquarters that severe drought, which is still continuing to develop, has caused 2.35 million mu of crops in Yunnan drought, and 1.441 million people and 827,000 head of livestock have difficulty drinking water.
