In recent years, the party and the country to environmental governance as a new era of socialism with Chinese characteristics of the basic guarantee of the development of various undertakings, clean air is a necessary condition for human health survival, quality air quality is a beautiful livable important indicator. The diurnal, monthly and annual changes of PM2.5 in Gansu Plateau in recent years were tracked and analyzed by means of instrument measurement and mathematical statistics. Based on the analysis of the data model, the promotion strategies are put forward from the perspective of human health.

Composite fabrics based on Polytetrafluoroethylene (PTFE) polymer displays several notable properties. They are waterproof, windproof, permeable to moisture and thermally insulating at the same time. In the present study, PTFE fibers are used as raw material to make fiber membranes. The film is formed by crisscrossing interconnected fiber filaments and the related air permeability: tensile creep characteristics and other properties are tested. The results show that the pore size, thickness, and porosity of the film itself can affect the moisture permeability of the film. The water pressure resistance of the selected fabric is 8.5 kPa, and the moisture permeability is 7038 g/(m 2 •24 h).

Based on the perspective of environmental safety, this study uses literature, instrument measurement and data statistics to study the physical exercise of the masses in the Gansu Plateau. It points out the environmental characteristics of the Gansu Plateau and the impact of the plateau environment on human health. Environment construction strategy. According to the WHO, outdoor environmental air pollution in urban and rural areas caused 4.2 million premature deaths in 2016 due to exposure to particulate matter (PM2.5) with a diameter of 2.5μm or less, which can cause cardiovascular and respiratory diseases and cancer. The World Cancer Organization’s International Cancer Research Institute conducted an assessment in 2013 and found that outdoor air pollution has a carcinogenic effect on humans. The particulate matter composition of air pollution is closely related to the increase in the incidence of cancer, especially lung cancer. [1] A study by Kunai et al, Points out that outdoor air pollution causes approximately 800,000 deaths worldwide each year, and the total healthy life expectancy of the world population is reduced by approximately 4.6 million years. Among them, twice as many people die each year as a result of traffic accidents. [2] Environmental pollution has severely affected our work and life, especially the haze weather in recent years has seriously harmed our physical and mental health.
