The relevant person in charge of the Eco-Environment Bureau revealed in the forum “Towards Reform and Opening-up†that the cumulative concentration of PM2.5 in Beijing in the first ten months of this year was 49 μg/m3, a year-on-year decrease of 18.3%, a record low. At the same time, the concentration of sulphur dioxide in the air in 2017 was only 8 μg/m3, which was 93.3% lower than the highest in 1998. At present, the concentration of sulphur dioxide in the air in the city is equivalent to the average level in Europe and America.
According to reports, since 1978, Beijing's economy and society have continued to develop rapidly, and the quality of the ecological environment has continued to improve. In 2017, the concentration of sulfur dioxide in the air was only 8 μg/m3, which was 93.3% lower than the highest in 1998. In fact, since 2004, the concentration of sulfur dioxide in the air of this city has begun to reach the national standard and is currently equivalent to the average level in Europe and America. The concentration of nitrogen dioxide and PM10 also decreased.
Since the monitoring of PM2.5 in 2013, the PM2.5 concentration in the air of this city has decreased year by year. In 2017, it decreased by 34.8% compared with 2013, reaching 58 μg/m3, successfully completing the first phase of national gas pollution control. As of the end of October this year, the cumulative concentration of PM2.5 has dropped to 49 micrograms per cubic meter, down 18.3% year-on-year, a record low.
At the same time, the water quality of the main centralized drinking water sources such as Miyun Reservoir has reached the national standard, and the water quality of rivers and lakes has been steadily improved. In 2017, the proportion of excellent water bodies in the city has increased to 36%, eliminating 52 black and odorous water bodies in the built-up area. The soil environment is generally clean. The eco-environmental quality index is maintained at a “good†level and is stable.
Since the reform and opening up, the scale of green space in Beijing has increased. Compared with 1980, the city's forest coverage rate increased from 12.8% to 43%, the urban green coverage rate increased from 20.08% to 48.2%, and the per capita park green area increased from 5.14 square meters to 16.2 square meters. There are 21 nature reserves of all levels, accounting for 8.4% of the country's land area, and play an important ecological conservation function.
The relevant person in charge said that Beijing's ecological environmental protection undertakings have achieved fruitful results, benefiting from the high attention of the Party Central Committee, the deepening of understanding, the improvement of institutional mechanisms, strong comprehensive support and the participation of the whole society.
According to reports, the city's pollution control path continues to expand. In terms of emission reduction methods, from single project emission reduction to comprehensive project emission reduction and management emission reduction; in management means, from relying solely on administrative means to the rule of law, economic, technical and administrative means; In terms of strategy, from the end of pollution control to the source control and the whole process supervision of energy and industrial restructuring; in the governance system, from the government’s “single fight†to “party leadership, government leadership, corporate responsibility, public Participate in; in the governance space, from local pollution control to regional collaboration.
In addition, technology monitoring continues to strengthen. Focusing on the problems of drinking water source protection, gas pollution prevention and other problems, and obtaining a number of important scientific research results such as PM2.5 source analysis. Accelerate the construction of an ecological environment monitoring network, and establish an automatic monitoring system for environmental quality such as gas and a monitoring system for key pollution sources. Relying on the high-density PM2.5 monitoring network, it will accurately enforce the high-value areas and improve efficiency. Carry out international cooperation, introduce advanced technology, experience and projects, and at the same time tell the story of Beijing.
