9.21 million acres of forests and sea are the wind -blocked sand of the capital

Today is the 28th "World Control and Treatment of Desertification and Drought Day", and it is also the implementation of the Beijing -Tianjin wind and sand source treatment project for 20 years. The reporter learned from the Beijing Forestry Working Station that in the past 20 years, the project has completed a total of 9.219 million mu of forestry forests, building a Gyeonggi green barrier to ensure the ecological safety of the capital and injecting green kinetic energy into the coordinated development of Beijing -Tianjin -Hebei.

Twenty years ago, Beijing was plagued by wind and sand. Beijing began in 2000. In 2002, the Beijing -Tianjin wind and sand source governance project was officially launched. Through measures such as trees and grass, retreating farmland, small watershed, grassland governance, ecological immigration, etc., vegetation The purpose of preventing sand prevention and sand control.

The project has been divided into two periods. From 2000 to 2012, the construction of the first phase of the first phase of the Beijing -Tianjin wind and sand source governance actually completed 7.08 million mu of forestry forest forests, which put the sandy area and the barren mountains in green. Landscape. The second phase of the project launched in 2013 began to march into areas with barren soil, lack of water, and inconvenient transportation, and the difficulty of forestry has greatly increased. With the help of the new development concept, the project pays more attention to improving the quality of forest vegetation and further consolidation and enhance the ecological function of mountains. According to the different types of ground areas in the mountains, there are local tree species such as oil pine, pine -side, deciduous pine, and ingot maple to further enrich the plant varieties, improve the structure of the forest, and at the same time protect and plant shrubs and native herbs according to local conditions. At the stage of engineering design, construction, acceptance, etc., experts and technical personnel have controlled the first pass to keep the high -quality development. As of now, the second phase of the project has actually completed 2.139 million mu of camping forests.

As the saying goes, "three -point, seven points." The city also launched the inefficient forest reconstruction project, through forest health care, and conducts scientific operations on high density forest land, allowing each tree to exert the greatest ecological value, further improve the forest to maintain soil, wind and sand, adjust the air, and solid carbon. The ecological role of the remittance.

Twenty years of green enters and sand retreat. In today's Beijing, the trees are greener and the sky is blue. Those spring that encounters sand and dust has become a memory. According to statistics, the Beijing -Tianjin wind and sand source governance project has completed 9.219 million mu of camping forests, and the forest coverage rate of Beijing mountains has reached 58.8%, an increase of 19 percentage points from 2000. The contribution rate of Beijing -Tianjin Fengsha source management project has reached more than 90%. The estimation shows that the engineering area can reduce the amount of soil and soil loss by 54.3 tons/hectares each year. A variety of wild animals and plants have returned to people's vision. The water quality of the large water basin in Beijing -Miyun Reservoir has maintained more than the II standard for many years. (Source: Beijing Daily)
