China News Service, Beijing, June 17 (Reporter Yu Lixiao) With the continuous advancement of sand prevention and control projects such as the second phase of the Beijing-Tianjin sandstorm source control project and two rounds of million-mu afforestation and greening construction, as of the end of 2020, Beijing The forest coverage rate of the city has reached 44.4%; the mountain forest coverage rate has reached 58.8%, an increase of 19% over 2000. More than 60% of the city’s land has been covered by greenery.
June 17, 2021 is the 27th World Day to Combat Desertification and Drought. The Beijing Municipal Bureau of Landscaping and Landscaping revealed the above data.
At the beginning of the founding of New China, the forest coverage rate in Beijing was only 1.3%. The five sand-hit areas in Kangzhuang, Changping, and Chaobai River, Yongding River, and Dasha River Basin had a total area of 2.475 million mu. There was no forest vegetation protection, waterlogging, and sand damage. Natural disasters such as drought, wind and sand occur frequently.
In the 1950s, the average annual dusty weather in Beijing reached 26 days.
Beginning in the 1980s, Beijing has successively carried out the "Three Norths" shelterbelt project, farmland forest network, and greening and afforestation in key wind-sand-hazard areas. Large-scale sand prevention and control have achieved remarkable results.
As a national ecological project to curb the hazards of sandstorms, the Beijing-Tianjin sandstorm source control project was launched in June 2000. Seven districts including Mentougou, Fangshan, Changping, Pinggu, Huairou, Miyun, and Yanqing were included in the scope of the project, through tree planting. , Returning farmland to forests, and comprehensive management of small watersheds, etc.
At present, the Beijing-Tianjin sandstorm source control project has completed a total of 8.96 million mu of afforestation and afforestation tasks. At the same time, it has also achieved a small watershed comprehensive management area of 748 square kilometers, artificial grass planting 90,000 mu, and ecological relocation of 14,934 people.
Beginning in 2012, Beijing has launched a million-mu plain afforestation project, highlighting the use of abandoned gravel pits, barren beaches and wasteland for afforestation, increasing ecological restoration efforts in the five sand-hazardous areas, and creating multifunctional forests with wind-proof and sand-fixing, landscape recreation, etc. 253,000 acres, the five sand-hazardous areas have been thoroughly controlled.
Large green areas suppressed the raging wind and sand, and Beijing’s sand and dust weather was significantly reduced.
According to statistics from the Beijing Observatory, the dust in Beijing was the worst in the 1950s, with as many as 26 days a year.
From the 1960s to the 1980s, the number of dust days declined, fluctuating between 10-20 days.
After the 1990s, it was significantly reduced to about 5 to 7 days. In recent years, this number has dropped to 3 days.
According to Hu Jun, director of the Desert Control Office of the Beijing Municipal Bureau of Landscaping, during the "14th Five-Year Plan" period, the city will continue to promote a new round of afforestation and greening of one million mu with high quality. In 2021, it is planned to add 150,000 acres of afforestation, and 86,300 acres have been completed. (Finish)Keywords:
