The role that planning departments can play in improving the atmospheric environment and controlling smog is as follows:
1. Improve public services, including the renovation of urban heating facilities, the development of public transportation, and the construction of green spaces in large areas. Attaching importance to the construction of green space, in addition to large parks, all kinds of exquisite small and medium-sized green parks are all over the city.
2. Stipulate that only smokeless fuel can be used in urban areas; Large-scale renovation of residents' traditional stoves, and gradual introduction of central heating in winter to reduce the use of coal.
3. Adjust the industrial structure, vigorously relocate and compress traditional industries, especially the manufacturing industry, move from industrialization to "de-industrialization", and focus on the development of the service industry represented by the financial industry.

Planning departments can make a rational layout to bring together high-energy polluting companies.
Coordinate and cooperate with the environmental protection department.
Provide scientific evidence for ** and related departments.

It's been a long time since I graduated, and I will briefly talk about my opinion: according to the official words, the biggest source of pollution comes from car exhaust, which I think is a little nonsense. Personally, I think so: first.
1. Desertification in the central and western regions of Inner Mongolia is more serious, and it is brought to the central, eastern and northeastern parts of China by the monsoon, which is the main condensation - dust in hazy weather. Clause.
2. Automobile exhaust emissions. In Beijing, for example, there are more cars than bicycles, and the exhaust emissions of cars are very high in nitrogen and sulfide, which pollutes the air. Third, there is a problem in the layout of the urban design, the air inlet or outlet of a city is blocked by high-rise buildings, resulting in air vortex in the city, which is not conducive to air renewal.

1. Implement pollution prevention and control measures such as coal control, vehicle control, oil control, and pollution control. This is a document issued by the local **, and there is a strict control of serious polluting enterprises by the Environmental Protection Bureau, reducing the emission of corporate waste and keeping the air clean.
2. Afforestation. Afforestation is of great significance for regulating climate, conserving water and reducing air pollution. This is because trees absorb carbon dioxide and release oxygen.
And it can withstand the wind and sand. It can also beautify the environment. According to different management purposes and characteristics, artificial afforestation can be divided into five types: timber forest, shelter forest, economic forest, charcoal forest and special purpose forest.
3. Strengthen the awareness of environmental fiber protection. The protection of the atmospheric environment is related to the fundamental interests of the people, the sustained and healthy development of the economy, the building of a moderately prosperous society in an all-round way, and the realization of the Chinese dream of the great rejuvenation of the Chinese nation. It is necessary to strengthen the people's awareness of environmental protection, urge everyone to protect the environment, reduce the discharge of waste, carry out propaganda and education in rural areas, and prohibit straw burning and other behaviors that pollute the environment.
4. Reduce emissions. Electricity generation requires the burning of coal, and less than 30% of the coal that is actually burned is converted into electricity, and the rest is emitted. Encourage power generation and thermal energy enterprises to use clean energy for power generation.

Fog or haze is a disastrous weather that has a significant impact on roads, railways, aviation, shipping, power supply systems, crop growth, etc. Fog and haze will cause air quality to deteriorate, affect the ecological environment, and bring great harm to human health.
In foggy and hazy weather, bacteria and viruses are often present in the air, which can easily lead to the spread of infectious diseases and the occurrence of various diseases.
Air pollutants in cities are not easy to diffuse, which aggravates the toxicity of sulfur dioxide, carbon monoxide, nitrogen oxides and other substances, and endangers human health.
In winter in foggy and hazy weather, if the air pollution is serious, it may form toxic fog such as smoke (fog) or black smoke, which seriously threatens people's lives and health.
-
adjust the industrial structure and reduce the proportion of seriously polluting industries;
Strengthen management, polluting enterprises to meet the standard discharge;
adjust the energy consumption structure and use clean energy;
develop science and technology to improve energy efficiency;
strengthen publicity and education to raise citizens' awareness of environmental protection;
develop public transport to reduce the use of private vehicles;
Plant trees and grasses to increase the area of urban green space.
-
Throw less garbage, reduce vehicle exhaust, and reduce the emission of three wastes from industrial enterprises.

1. Cashmere goats in Inner Mongolia will be uprooted sooner or later, which will seriously lead to desertification of grassland.
2. Mineral mining in many areas of the north, especially coal mining, sand and gravel mining leads to land loss and environmental degradation.
3. Coal burning in industrial boilers causes air pollution.
4. Air pollution caused by sulfur dioxide emissions from industrial production.
Reducing air pollution and smog must start with the most widespread and devastating projects that cause the most pollution. In addition, a large proportion of funds will be invested in the restoration of the ecological environment. Expanding the area of vegetation is an effective control method in the long run.
-
Drive less, walk more, refuse coal-fired boilers.

Improving the coordination mechanism for regional environmental construction is an important measure to control haze.
Haze pollution is a regional environmental problem, and regional coordination and joint prevention and control are required for both pollution source analysis and pollution control. At present, the Beijing-Tianjin-Hebei region has initially established a basic framework for regional environmental management, and Beijing, Tianjin and Hebei have signed the "Agreement on Further Strengthening Cooperation on Environmental Protection" and the "Framework Agreement on Strengthening Cooperation in Ecological Environment Construction" respectively, with a view to achieving integrated and coordinated development.

If it is dust-proof or anti-haze, it is still KN100 level mask with good protective effect. It is recommended to choose a high-grade silicone material for the mask. It is recommended to choose a double-piece design for the filter, the filter is double-sided or pleated, the area is large, and the breathing is relatively smooth.
At present, due to the improvement of the level of mechanization, the relatively high dust concentration in the working environment, the wrong choice of masks, excessive attention, ignoring the protective effect, quality, comfort and service life of masks, are easy to lead to the selection of low-grade and counterfeit products, resulting in occupational injuries. It is recommended to combine the GB2626-2006 standard to scientifically select dust masks to effectively prevent respiratory injuries.
d Liquefaction Dry ice has only gaseous solid two-phase in the atmosphere and therefore cannot be liquefied.
