The rain in the south will continue until the Spring Festival. Will it solve the drought problem in Wenzhou, Zhejiang and other places?

From the end of September 2020 to the end of January 2021, Zhejiang Province has maintained sunny weather with less rain, with an average rainfall of less than 100 millimeters, especially in the southeastern coastal areas. A relatively serious local drought has occurred, which can be said to be a severe drought that is rare in 50 years. In the southeastern part of Zhejiang Province, there are areas such as Yueqing in Wenzhou City, Wenling in Taizhou City, Xiangshan in Ningbo City and other areas, as well as Zhoushan City and some mountainous areas and islands in Zhejiang. There have been relatively serious droughts.

The impact of this drought on areas such as Wenzhou, Taizhou and Ningbo is very large. Many areas have stopped a large number of water-using units such as swimming pools, bathrooms and car washes, and restricted the use of hotels, enterprises and institutions. The unit's water usage time and water consumption. The Shanxi Reservoir in Wenzhou, Zhejiang Province has dried up in large areas, which has seriously affected local agricultural production.

The Central Meteorological Observatory has issued a rainfall weather forecast. The scope of this rainfall in the south will continue to expand, and this heavy rainfall is mainly concentrated in Yunnan and South China, which is beneficial to alleviating the drought. The Central Meteorological Observatory predicts that the rainfall range in the south will further expand starting from February 8. Moderate to heavy rain will occur in the eastern part of Southwest China to southern Jiangnan and South China, and light to moderate rain will occur in most of Jiangnan and South China. Affected by the lack of rainfall in the first half of 2020, the moderate to severe drought that occurred in southern Jiangnan, South China and Yunnan is expected to be alleviated to a certain extent after this round of rainfall. But rainfall cannot completely solve the water shortage problem.

Zhejiang Province has historically been a province with moderate water shortages. The annual per capita water resource in Zhejiang Province is 1,702 cubic meters, which is 20% lower than the national standard. This is mainly due to the lack of water resources. The distribution is extremely uneven. The use of a large amount of water resources is not well managed. Most of the freshwater resources flow into the sea and are not effectively utilized. Moreover, water reserves are obviously insufficient in several densely populated areas of Zhejiang Province. Therefore, improving the utilization and storage of water resources is the key to truly solving the water shortage in Zhejiang Province.

First of all, we must vigorously develop forest resources and increase the area of ​​​​forests, which can effectively conserve water sources and regulate the regional climate to form good regional rainfall. Secondly, improve the utilization efficiency of water resources and reuse limited water resources. The city's sewage resources can continue to be recycled after treatment. Vigorously promote water-saving technologies and equipment. Only in this way can the impact of drought on Zhejiang Province be fundamentally solved.
