The future temperature in the northeast region will continue to rise and flood disaster risk

People’s Network Shenyang October 27th (Filial Piety) On October 26 And propose advice.

In 2021, the Northeast Regional Meteorological Center organized Liaoning, Jilin, Heilongjiang Province meteorological department completed the second Northeast regional climate change assessment, and published the "Northeast Regional Climate Change Assessment Report: 2020 Policy Summary" (hereinafter referred to as "Report" .

The observed climate change shows that from 1961 to 2017, the annual average temperature rise rate in the Northeast region is ° C / 10 years, higher than the temperature rise rate in the same period of the country and the rise in temperature in nearly 50 years, of which the average temperature rise rate of Liaoning is ° C / 10 years.

During the same period, the number of fresh water days in the Northeast region reduced the day, the precipitation intensity increased with millimeters / day / 10 years, and the number of fresh water days in Liaoning reduced the rate of days / 10 years, and the precipitation intensity was mm / day / 10 years of reinforcement. The facts mentioned in the "Report" also include the sunshine, the wind speed is reduced, the snow is shortened, the maximum snow is increased, the maximum frozen soil depth decrease is reduced.

For future climate change trends and risks, the Northeast Regional Meteorological Center Analysis Prediction Risk drop. The relevant person in charge of the Liaoning Provincial Meteorological Bureau said that the climate warming will have a significant impact on the distribution of the regional water and heat resources, and the fields of agriculture, natural ecosystems, energy and other areas will have a significant impact, and the overall performance is "disadvantaged". It is recommended to increase the feature of heat in the future northeast area, choose the middle and evening cooked product species suitable for the region; retrofit and upgrade farmland infrastructure and water conservancy projects, enhance the abilities of agricultural response to more serious or more floods and drought disasters; curb black soil degradation. By establishing long-term hydrating mechanisms, the wetland recovery technologies that adapt to climate change, etc., protect and repair the wetland resources of Liaoning. At the same time, improve the building energy-saving design standards, carry out the assessment of photothermal climate resources, and scientifically control the energy consumption of urban heating.
