1. Environmental assessment: Before urban construction, the environment should be comprehensively assessed, including soil, water source and air quality, so as to assess the impact of construction on the environment and take corresponding measures to reduce the impact of construction on the environment.
2. Control of pollution sources: In urban construction, it is necessary to strengthen the control of pollution sources, such as strengthening the sewage management of industrial enterprises, limiting the number of motor vehicles, and promoting clean energy, so as to reduce the impact of pollution on residents' health.
3. Building public green space: The city should build public green space to improve the greening rate and air quality of the city. Public green space can not only provide places for residents to play, but also absorb pollutants in the air and purify the air.
