In this study, the air microorganism samples were collected through Andersen six stages sampler by using bacteria and fungi culture medium, and the time distribution characteristics of air microbial concentration of four functional areas in Taizhou were analyzed. The results showed that the concentration of bacteria, fungi and total number of air microbes of each functional area reached the lowest level at noon of a day; the concentration of bacteria in each functional region reached the lowest level in January and the highest level in April, however, the concentration of fungi and the total number of air microbes reached the highest level in September, and the annual distribution presented the wave pattern trend.
