Abstract: Many factors influenced the spac-etime distribution of the atmosphere pollen.By analysis of sampling the atmosphere pollen in difference months and analysis of sampling the atmosphere pollen in difference days in a month,we found that the atmosphere pollen mainly distributes the space between 0 and 50m,but pollen also distr ibute in 80m high space.Wind velocity,wind direction and temperature during the pollen formative period emerges as the most influential factors.In addition,relative humidity and distribution of high-rise also affect the space-time distribution of the atmosphere pollen in some extent.
