The CPC Central Committee and the State Council attach great importance to environmental protection as an important part of implementing the Scientific Outlook on Development, as an important means to transform the mode of economic development, and as a fundamental measure to promote the construction of ecological civilization. During the "Eleventh Five-Year Plan" period, the state took the significant reduction of the total discharge of major pollutants as a binding indicator of economic and social development, made great efforts to solve outstanding environmental problems, and made important progress in understanding, policies, systems and capabilities. Compared with 2005, the total amount of chemical oxygen demand and sulfur dioxide emissions decreased by 65438 02.45% and 65438 04.29% respectively, exceeding the emission reduction task. With the rapid development of pollution control facilities, the sewage treatment rate of the whole city has increased from 52% in 2005 to 72%, and the installed capacity of thermal power desulfurization has increased from 12% to 82.6%. Let rivers and lakes recuperate in an all-round way, deepen pollution prevention and control in key river basins and regions, and improve environmental quality. The proportion of surface water in the national control section is better than that of Class III, which is increased to 565,438 0.9%, and the average concentration of sulfur dioxide in urban air in China is reduced by 26.3%. Environmental law enforcement and supervision have been continuously strengthened, the comprehensive improvement of rural environment has achieved remarkable results, ecological protection has been effectively strengthened, nuclear and radiation safety is controllable, the awareness of environmental protection in the whole society has been continuously enhanced, and the participation of the people has been further improved, thus fully fulfilling the environmental protection objectives and key tasks of the Eleventh Five-Year Plan.

At present, the overall deterioration of the environmental situation in China has not been fundamentally curbed, environmental contradictions are prominent, and the pressure continues to increase. Water pollution is serious in some key river basins and sea areas, and atmospheric smog is prominent in some areas and cities. The discharge of major pollutants in many areas exceeds the environmental capacity. Environmental pollution in rural areas has intensified, with heavy metals, chemicals, persistent organic pollutants, soil, groundwater and other pollution. In some areas, the ecological damage is serious, the ecosystem function is degraded, and the ecological environment is relatively fragile. Nuclear and radiation safety risks have increased. The people's requirements for the environment are constantly improving, and sudden environmental incidents remain high. Environmental problems have become one of the important factors threatening human health, public safety and social stability. The pressure of global environmental problems such as biodiversity protection is increasing. The legal system of environmental protection is not perfect, the investment is still insufficient, the law enforcement power is weak, and the supervision ability is relatively backward. At the same time, with the sustained growth of population, the rapid advancement of industrialization and urbanization, the total energy consumption continues to rise, pollutant emissions will continue to increase, and the environmental constraints of economic growth are increasingly strengthened.

The situation is the reason. If possible, learn more about the government's principles and policies on related issues in recent years, so that they can be basically solved.
