The main stream of the Huaihe River is close to the closure of Jiangsu Province to replenish soil and water conservation production
Xinhua News Agency, Nanjing, 14 Nov (Reporter Zhao Jiulong) on the 14th, the reporter learned from the Flood Control and drought Relief headquarters of Jiangsu Province that under the dual effects of less rainfall and dry water, the storage of lagoon reservoir is obviously insufficient, and the main stream of the Huaihe River is close to being cut off. Small reservoirs such as Xiangyanghu Reservoir in northern Jiangsu are close to drying up, and the phenomenon of dead seedlings appears in some areas. At present, many departments in Jiangsu Province have made every effort to implement the diversion of river water from the north to the east to ensure the livelihood of the people.
From May to July this year, a series of droughts occurred in spring and summer in Jiangsu Province. Since late August, the province has once again sustained drought and lack of rain, and most areas have experienced serious meteorological droughts. Hydrological monitoring shows that since mid-September, most of the accumulated rainfall in about 60 days between Jianghuai and the central and western parts of southern Jiangsu has been less than 10 mm, reaching a new historical low in the same period. At the same time, the amount of water coming from the upper reaches of the Huaihe River has decreased, with only 726 million cubic meters of water coming from the main stream of the Huaihe River since July, which is 95% less than that of the same period of the year. Since mid-September, the main stream of the Huaihe River has been close to being cut off again.
The monitoring data show that the water level of Hongze Lake, Luoma Lake, Weishan Lake and Shilianghe Reservoir in northern Jiangsu is more than 1 meter lower than the normal water level, and Hongze Lake is about 1.75 meters lower than the normal water level. The total water storage capacity of the "three lakes and one reservoir" is 2.39 billion cubic meters, 46 percent less than that of the same period of the previous year. Drought appeared in some areas, the soil moisture was generally poor, and the phenomenon of dead seedlings appeared in some areas of northern Jiangsu.
In view of the serious meteorological drought, Jiangsu Province has allocated water sources as a whole, dispatched water conservancy projects, strengthened water storage and water conservation in lakes and reservoirs, and increased the scale of river water transfer to the north of Jiangsu Province. More than 7 billion cubic meters of water has been replenished to the northern part of Jiangsu Province. In addition, every effort has been made to implement the diversion of river water to the east. As of November 9, the cumulative amount of water diverted from the river by the east gate and the Gaogang hub has reached a record high of 10.99 billion cubic meters since the beginning of this year.
Jiangsu is also constantly strengthening the ability of farmland to resist natural disasters. In the whole year, it plans to invest 7 billion yuan to build 3.5 million mu of high-standard farmland and more than 400,000 mu of high-efficiency water-saving irrigation. The proportion of drought and waterlogging farmland in the province has increased by 4 percentage points. Jiangsu has made it clear that more than 380000 mu of efficient water-saving irrigation will be added to the province by 2020.
