After the analysis of the observed data of pollen in the suburban and urban areas of Kunming city from January 2000 to December 2001,it is found that the periodical and seasonal characteristics of pollen concentration variation in a year are clear.Based on the relation of meteorological elements and pollen concentration in air,a prediction equation of pollen-allergy disease was statistically developed.Then the equation is verified and improved by using the actual incidence of pollen-allergy from hospitals,and humidity,wind speed and temperature.The accuracy of the forecast equation is quiet satisfactory.
