The report of the State Council on the environmental situation and the completion of environmental protection objectives in 2021 was submitted to the Standing Committee of the National People's Congress for deliberation on the 18th. The report shows that in 2021, the quality of the national ecological environment has improved significantly. Huang Runqiu, Minister of the Ministry of ecological environment, said in a report commissioned by the State Council that in 2021, the ratio of days with excellent air quality in prefecture level and above cities was 87.5%, an increase of 0.5 percentage points year-on-year; PM2. 5 the average concentration was 30 μ g / m3, a year-on-year decrease of 9.1%. The number of cities with air quality standards reached 218, an increase of 12 year-on-year. Among them, the air quality in key areas has improved significantly, and the improvement range of Beijing Tianjin Hebei and its surrounding areas, the Yangtze River Delta and Fenwei plain is generally higher than the national average. In 2021, the environmental quality of surface water in China will improve steadily. The proportion of surface water quality is 84.5% compared with that of section I to section III in 2020; The proportion of sections with inferior class V water quality is 1.2%. Water quality in key river basins continued to improve. The water quality of the Yangtze River Basin and the Pearl River Basin continued to be excellent, the water quality of the Yellow River Basin improved significantly, and the water quality of the Huaihe River Basin and Liaohe River Basin improved from mild pollution to good. The groundwater quality is generally good. The sea water quality in the sea areas under China's jurisdiction continues to improve as a whole. Huang Runqiu said that the eight binding indicators in the field of ecological environment in the national economic and social development plan in 2021 were successfully completed. Among them, the ratio of days with excellent air quality in cities at prefecture level and above is 2.3 percentage points better than the annual target, PM2.5 percentage points 5. The proportion of concentration decline is 13.6 percentage points better than the annual target, and the proportion of class I to III water quality sections of surface water is 1.4 percentage points better than the annual target. The report points out that the foundation for a stable and sound ecological environment is not yet solid. At present, 29.8% of urban PM2 5. The average concentration exceeds the standard, and regional heavy pollution weather processes still occur from time to time. The improvement effect of water ecological environment is not stable. It is difficult to eliminate class V sections in a few areas. Cyanobacteria bloom in some key lakes remains high. There are pollution risks around pollution sources and groundwater drinking water source protection areas, and problems such as imbalance of water ecosystem need to be solved urgently. In order to protect the blue sky and clear water, in 2022, we should organize and implement landmark campaigns such as the elimination of heavily polluted weather, the prevention and control of ozone pollution and the control of diesel truck pollution; Organize and implement landmark campaigns such as the treatment of urban black and odorous water bodies, the protection and restoration of the Yangtze River, the ecological protection and treatment of the Yellow River and the comprehensive treatment of key sea areas, and continue to carry out the investigation and regulation of sewage outlets.
