Observation today ｜ How can Sichuan win the drought -resistant "tough battle" in the most drought in the past ten years?

On August 11, the Sichuan Province Flood Control and Drought Resistance Headquarters decided that from 18:00 that day, the fourth -level drought resistance response launched on July 15th was upgraded to the third -level drought emergency response. Near a month, Sichuan's drought resistance and disaster reduction once again "sounded the alarm", and the last provincial level launched a third -level drought resistance emergency response, which dates back to the period of Sichuan South Drought in 2011. Why should I upgrade the level of emergency response to drought resistance? What is the current Sichuan drought situation and how to deal with it next?

For more than ten years, our province has launched a third -level drought resistance response during the Sichuan South Drought in 2011. Why should we improve the level of response? From the perspective of the current situation of drought, the drought that lasted more than a month this year has become the heaviest in ten years; from the perspective of weather trends, on August 10, the Provincial Meteorological Observatory upgraded the high temperature blue warning to a high -temperature orange warning. From 7:00 on the 11th to 17th to 17th At the time, the province has issued 70 high -temperature red warning signals. In the next 10 days, the high temperature weather in the basin will continue; from the perspective of the main rivers in our province, the next 10 Lord will take the rivers and rivers in the next 10, and the rainfall in mid -to -late August will be less than the same period. In general, the drought resistance of the province is more severe. Drought drought in southern and part of the basin in the basin of the basin will continue to develop.

Since July this year, the continuous high temperature and hot weather in our province has led to some cities and prefectures in the northwest of the basin, northeast of the basin, southern basin, central basin, southwestern basin, and west. 69 counties (cities, districts) in the city (state). According to statistics from the Sichuan Water Safety and Water Disaster Disaster Defending Center, as of August 11, the province's cumulative drought in the field of field crops was nearly 287.9 ​​thousand hectares. 125,000, the most drought in our province in the past ten years.

So, why did our province the most severe drought in the past ten years? The first is the abnormal high temperature weather this year, the high temperature duration and strong strength. According to the statistics of the Provincial Meteorological Observatory, since July, there have been two obvious continued high temperature weather process. The first stage appeared from July 4 to 16, and the second stage has continued from July 25. Since July, high -temperature weather in 129 counties in the province, of which the maximum temperature of meteorological monitoring stations such as Gulin, Qu County, Hejiang and other meteorological monitoring stations exceeded 42 ° C. The average temperature since July is also the highest in history. Significantly high 2-3 ° C, and the local area is above 3 ° C. In addition, after the flood this year, the rainfall of our province has shown a monthly decrease. Especially for nearly 40 days in July to the so far, most of the province's precipitation is 20-90 % less, of which most of the middle of the basin is 60 % less than 60 % less than 60 % less. Above, the average precipitation in our province has ranked first in the same period in history since July.

Next, how can our province deal with drought development and win this "hard battle" of drought resistance? At present, the critical period of flood prevention in our province is the most concentrated period of rainfall in the same period of the same year. Will there be a "timely rain" to relieve drought in the future? According to the Provincial Meteorological Observatory, from August 19th to 21st, the province will have a relatively obvious precipitation weather from west to east. At that time, the continuous high temperature weather in the basin will end, and drought may be relieved to a certain extent.

However, according to the current development trend of drought, the relevant person in charge of the Provincial Department of Water Conservancy said that all departments from all over the province should make full preparations for "preventing drought, anti -drought", and implementing accurate research and judgment and scientific policies, and implementing drought anti -insurance control measures in advance. Strive to minimize drought loss. From August 12, the Provincial Water Resources Department will continue to send a working group to Guang'an, Dazhou, Luzhou and other places with heavy droughts to carry out drought supervision and guidance. The Provincial Department of Water Conservancy also requires all localities to take various measures such as "storage, quotation, adjustment, and raising" to fully ensure the production of living and living water and agricultural production water for the masses. In response to the current situation of various types of water conservancy projects in our province compared with the same period of water storage in the same period last year, localities should also combine drought resistance and disasters and water storage to ensure water storage at the end of the flood. In order to resist drought and disaster reduction and production of living water this winter and next spring, providing sufficient water for electricity.
