On May 28, the Beijing City Ecological Environment Bureau held a press conference and released the "Bulletin on the Status of the Ecological Environment of Beijing City in 2023." The bulletin is supported by data and comprehensively demonstrated the trend of continuous improvement of the ecological environment in Beijing City.
PM2.5Compliance has been achieved for three consecutive years, and air quality improvement has achieved solid results.
Fine particulate matter (PM) in the air in 20232.5) The average annual concentration is 32 micrograms/cubic meter, reaching the national air quality secondary standard for three consecutive years. Sulfur dioxide (SO2), nitrogen dioxide (NO2) and inhalable particulate matter (PM10) The average annual concentrations are 3, 26 and 61 micrograms/cubic meter respectively, which have been stable to meet the standards for many consecutive years.
Since 2013, while high-quality economic and social development, Beijing City has achieved significant overall improvements in air quality. Compared with 2013, the average annual concentration of major pollutants in the city's air has dropped significantly, among which PM, which is most concerned by the public.2.5The average annual concentration dropped by 64.2%, and compared with 2019, PM was higher than that in 2019 at similar levels of socio-economic activity and diffusion conditions.2.5The average annual concentration has dropped by 23.8%, the environmental benefits of various air pollution control measures have continued to be released, and the overall air quality has maintained an improvement trend. The number of days with good air quality was 271, an increase of 95 days from 2013 and an increase of 31 days from 2019. The public's sense of blue skies was significantly enhanced.
The city's water environment quality is stable and the water ecological condition is good
In 2023, Beijing City will monitor a total of 105 sections of the five major system rivers with a length of 2,551.6 kilometers, of which more than 70% of the river length has excellent water quality, and no river is inferior to Class V. Compared with 2013, the proportion of river lengths with excellent water quality increased by 21.5 percentage points; compared with 2019, it increased by 16.2 percentage points.
More than half of the city's rivers have excellent water ecological conditions. Aquatic insects such as mayflies, stonflies, and stonflies, which are often used to indicate clean water bodies, have a large number of species in mountainous rivers such as Huaijiu River, Juma River, and Upper Baihe River, and are also found in plain rivers such as Beisha River, Tonghui River, and Dongsha River. The second-level aquatic wild protected animals in Beijing City, such as broad-fin, horse-fin, and black-fin, have been widely distributed.
The ecological environment is in excellent condition and rich in biodiversity
The city's ecological environment quality index (EI) is 70.8, and the quality of the ecosystem remains stable. The ecological conservation area continues to maintain a good ecological environment. EI in the capital's functional core area, central Urban area and plain area continues to maintain a good level. Among them, the ecological environment of the city's centralized construction areas is in good condition, with a green viewing rate of 26.96%.
Beijing City is one of the most biodiverse metropolises in the world, and its good natural endowment has attracted more and more animals to settle here. In 2023, the city's biodiversity survey recorded 73 natural and semi-natural ecosystem formations on the spot, and a total of 136 species were recorded from 2020 to 2023. The types of natural and semi-natural ecosystems recorded in the survey continue to increase, among which, 23 natural and semi-natural ecosystems have been recorded in the central Urban area. Through continuous near-natural ecological restoration and construction, the composition and structure of the ecosystem have been optimized.
The overall quality of the soil ecological environment is good
Soil environmental risks are effectively managed and controlled. Promote classified management of agricultural land, strengthen risk prevention and control of construction land, and strictly protect unused land. The soil fertility and buffering capacity are mostly above medium, and the soil fertility of agricultural land meets the growth and development needs of most crops.
The quality of the city's acoustic environment remained stable. The quality of the radiation environment remains normal.
While announcing that the city's ecological environment continues to improve, the press conference also introduced new progress in the construction of beautiful Beijing from multiple aspects.
New results have been achieved in the construction of ecological civilization
Vigorously implement the Green Beijing strategy, coordinate the promotion of carbon reduction, pollution reduction, green expansion, and growth, promote 59 key tasks in the city's ecological civilization construction, and form 171 policy results such as spatial protection planning in the upper reaches of Miyun Reservoir. Efforts have been made to solve typical ecological and environmental problems around a group of people and promote high-quality development.
Pollution prevention and control continues to deepen
Condensing NOx emission reduction, in-depth treatment of VOCs and co-treatment of "three dusts", a total of 773,000 new energy vehicles have been promoted, and "one factory, one policy" in-depth treatment has been implemented. The city's dust reduction volume is 3.6 tons/square kilometer·month, and the city's cleanliness has been significantly improved. "Three Rivers Rule" and "Three Places Co-management" have been solidly advanced and achieved solid results.
Ecosystem diversity, stability and sustainability continue to improve
Carry out remote sensing monitoring of human activities in important ecological spaces such as key nature reserves and ecological protection red lines to improve the diversity, stability and sustainability of ecosystems. Deepen the creation of ecological civilization demonstrations. In 2023, Chaoyang District and Changping District will respectively win the seventh batch of "Ecological Civilization Construction Demonstration Zones" and "Lucid waters and lush mountains are invaluable assets" practical innovation bases.
actively respond to climate change
Adhere to equal emphasis on mitigation and adaptation, and promote the transformation from dual control of energy consumption to dual control of carbon emissions. Improve the institutional system and introduce synergy and efficiency implementation plans for pollution reduction and carbon reduction. Improve the market mechanism, build a national voluntary greenhouse gas emission reduction trading market and officially launch it. Promote low-carbon innovation, Tongzhou District and Miyun District promote the construction of national climate investment and financing pilot projects; collect pilot projects such as advanced low-carbon technologies, low-carbon pioneers, and climate-friendly regions.
Strong promotion of joint prevention and control
Deepen joint construction, joint prevention and control, and carry out comprehensive air pollution control operations in autumn and winter for seven consecutive years, revise and issue emergency plans for heavy air pollution, and jointly respond to regional air pollution processes. Beijing and Hebei implemented a comprehensive plan for ecological and environmental protection in the Chaohe River Basin and signed a horizontal ecological compensation agreement for water source protection in the Yongding River Basin upstream of Guanting Reservoir. The concept of "co-governance, co-construction, and sharing" continues to be deeply rooted in the hearts of the people. The general public actively practices green and low-carbon life concepts and lifestyles, and tens of millions of people participate in environmental protection public welfare activities such as the 10th Beijing Ecological Environment Culture Week and "V Blue Beijing". Advanced models such as "Green Living Good Citizens","The Most Beautiful Green Families" and "100 Most Beautiful Ecological Environment Volunteers" have emerged widely.
Finally, spokesperson Wang Xuantong, director of the Ecological and Environmental Monitoring Division of Beijing City, said that in 2024, Beijing City will continue to useXiJinpingGuided by the idea of ecological civilization, in-depth studyXiimplementXiJinpingIn the spirit of the General Secretary's important speech at the National Ecological and Environmental Protection Conference, vigorously develop new productive forces, accelerate the green and low-carbon transformation of economic and social development, continue to deepen the battle against pollution, promote the continuous and stable improvement of the quality of the ecological environment, and provide high-quality ecology The environment supports the high-quality development of the capital and comprehensively promotes the construction of a beautiful Beijing.
