CCTV News: The reporter learned from the National Ecological and Environmental Protection Work Conference that in 2024, my country will continue to promote pollution prevention and control, and the ecological environment quality will continue to improve.

In terms of the battle to defend the blue sky, the PM2.5 concentration in cities at the prefecture level and above across the country was 29.3 micrograms/cubic meter, a year-on-year decrease of 2.7%, and it has steadily met the standards for five consecutive years.

The proportion of excellent days in the country reached 87.2%, an increase of 1.7 percentage points year-on-year. The proportion of heavy pollution days was 0.9%, a year-on-year decrease of 0.7 percentage points. Black and odorous water bodies in cities at the prefecture level and above are basically eliminated

In the battle to defend clear water, the completion rate of sewage discharge outlets into rivers and seas in the seven major basins and key bays reaches 90% and 84% respectively. The black and odorous water bodies in cities at the prefecture level and above are basically eliminated, and the proportion of black and odorous water bodies in cities at the county level exceeds 80%.

The proportion of excellent water quality sections in surface water in the country reached 90.4%, exceeding 90% for the first time, an increase of 1 percentage point year-on-year. The proportion of excellent water quality in nearshore waters is 83.7%, reaching the goals of the 14th Five-Year Plan ahead of schedule. The main stream of the Yangtze River has been stable at the Class II level for five consecutive years and the main stream of the Yellow River has been stable for three consecutive years. Focus on key areas and strive to achieve the ecological goals of the "14th Five-Year Plan"

Since the "14th Five-Year Plan", the national ecological environment indicators have made smooth progress. The Ministry of Ecology and Environment stated that it will further consolidate and improve governance results, focus on key areas to focus on key areas to carry out key breakthroughs, and ensure that all the goals and tasks of ecological and environmental protection in the "14th Five-Year Plan" are completed with high quality in 2025.

The Ministry of Ecology and Environment will strengthen air pollution control in key areas and key areas, with the main line of reducing PM2.5 concentration and strengthening coordinated control of multiple pollutants. Focus on promoting the control of total phosphorus in the Yangtze River Basin and total nitrogen pollution in the middle and lower reaches of the Yellow River. Strengthen the prevention and control of cyanobacteria water blooms in lakes such as Taihu Lake, Chaohu Lake, Dianchi Lake, and Erhai Lake to ensure the stable water quality of the main streams of the Yangtze River and the Yellow River, and the water quality of important lakes remains stable and improving.

Focusing on the Beijing-Tianjin-Hebei region and its surrounding areas, the Fenwei Plain, the Yangtze River Delta region, as well as the "Two Lakes", Chengdu-Chongqing, and the northern slope of the Tianshan Mountains, further strengthen the efforts to control air pollution. Focus on nationally controlled Class V water bodies such as some tributaries of the Yellow River, accurately manage and provide precise assistance, and achieve the goal of basic elimination of Class V water quality sections as scheduled. Continue to carry out special rectification and improve the long-term mechanism to prevent black and odor from returning.

Promote the ecological protection red line of ecological functions without reducing, area without changing, and nature without changing. Establish and improve standards and risk prevention and control systems to effectively ensure the safe use of centralized drinking water in cities and townships, as well as polluted arable land and key construction land.
