BEIJING, Beijing, May 29 (Reporter Chen Hang) On the 29th, the Beijing Municipal Bureau of Ecology and Environment released the Bulletin on Beijing’s Ecological Environment in 2022 (hereinafter referred to as the Bulletin), which "counted" the ecological environment in Beijing in 2022 and the new era for ten years, and comprehensively showed the changes of Beijing’s ecological "face value" in the past ten years.
According to the Bulletin, in the past ten years, Beijing has achieved a rapid decline in the concentration of major pollutants in the atmospheric environment while achieving high-quality economic and social development. Compared with 2013, the annual average concentrations of PM2.5, PM10, NO2 and SO2 all decreased by more than half in 2022. Among them, the average annual concentration of PM2.5 decreased from 89.5 μ g/m3 to 30 μ g/m3, with a cumulative decrease of nearly 60 μ g/m3.
According to the Bulletin, in 2022, the average annual concentration of fine particulate matter (PM2.5) in Beijing continued to decrease, reaching the second-class national air quality standard for two consecutive years, the water environment quality continued to improve, the soil environment condition remained good, the acoustic environment quality remained stable, the radiation environment quality remained normal, the ecological environment condition continued to improve, and the carbon dioxide emissions per 10,000 yuan of GDP maintained the best level in provincial regions.
The average annual concentration of PM2.5 has reached the second-class national air quality standard for two consecutive years.
According to the Bulletin, in 2022, PM2.5 in Beijing’s atmospheric environment was 30 μ g/m3, reaching the national secondary standard for two consecutive years. The annual average concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2) and inhalable particulate matter (PM10) were 3,23 and 54 μ g/m3, respectively, which reached the standard steadily for many years, and generally maintained a downward trend.
In the past ten years, Beijing has achieved a rapid decline in the concentration of major pollutants in the atmospheric environment while achieving high-quality economic and social development.
Compared with 2013, the annual average concentrations of PM2.5, PM10, NO2 and SO2 in Beijing in 2022 all decreased by more than half. Among them, the average annual concentration of PM2.5 decreased from 89.5 μ g/m3 to 30 μ g/m3, with a cumulative decrease of nearly 60 μ g/m3. The average annual concentration of SO2 has dropped from 26.5 μ g/m3 to 3 μ g/m3, with a drop of 88.7%, and has remained extremely low for many years, which is basically equivalent to the level of big cities in developed countries in the world. The number of excellent days was 286, an increase of 110 days; The days of heavy pollution were reduced from 58 days to 3 days. Good days have increased significantly, bad days have decreased significantly, and air quality has improved greatly in an all-round way. The effectiveness of air pollution control has been praised as "Beijing Miracle" by UNEP.
Dynamic elimination of inferior V water bodies
According to the Bulletin, in 2022, the quality of water environment in Beijing will continue to improve, and the annual average concentration of main pollution indicators of surface water will continue to decrease, and the inferior V water bodies will be eliminated dynamically. The quality of groundwater remains stable. The water ecology is in good condition.
In the past ten years, the water ecological environment in Beijing has achieved qualitative change. The proportion of excellent water bodies has increased significantly. In 2022, there were 105 sections and 2551.6 kilometers of rivers in the five major river systems, of which the length of rivers with excellent water quality accounted for 77.9%, an increase of 28.1 percentage points compared with 2013. Dynamic elimination of inferior V water bodies. The water ecology is in good condition, and more than half of the rivers in the city have reached an excellent level. Aquatic insects, such as Mayflies, stonefly and Shimoths, which are often used to indicate clean water bodies, are not only found in mountainous rivers, but also appear in rivers in plain areas such as Liangshui River, Dashi River and Liangma River. Five rivers in the city reappear as "flowing rivers" and run through the sea; The water volume of Miyun Reservoir reached a record high, and it was rated as the first batch of excellent cases of "beautiful rivers and lakes" in China by the Ministry of Ecology and Environment … … The water is clear and the shore is green, and the fish is shallow. The scene of harmony between people and water has become the norm.
The forest coverage rate will increase to 44.8% in 2022.
According to the Bulletin, in 2022, Beijing’s eco-environmental quality index (EI) was 71.1, which achieved continuous improvement for many years. The eco-environmental situation was excellent and the quality and stability of the ecosystem continued to improve. The forest coverage rate of the whole city will increase from 38.6% in 2013 to 44.8% in 2022. The types of ecosystems in the whole city are constantly enriched, the stability is gradually enhanced, and the sustainability is constantly improving.
