Air quality assessment is a crucial guarantee for the healthy development of a city. The current air quality assessment methods mostly focus on pollutants themselves, to some extent neglecting the significant role of human health in air quality evaluation. To objectively assess the air quality of different districts in Beijing, six pollutants, namely NO2, SO2, CO, O3, PM10, and PM2.5, were selected as evaluation factors, and the 14 major districts of Beijing were taken as the evaluation objects. The hourly concentration data of the six pollutants from July 6th to July 12th were integrated. On the basis of the traditional AQI air quality assessment method, two dimensions of humanistic care, time and space, were added. At the same time, the original method of using the main pollutants as the evaluation basis was changed. The fuzzy comprehensive evaluation method was used to comprehensively consider the impact of the six pollutants on human health, and the excess health risk was used to quantify the harm of pollutants. Finally, the air quality assessment of each day from July 6th to July 12th was completed.
