【Abstract】 Objective To study the influence of main meteorological parameters on the mosquito density. Methods With the data of mosquito density from 2005 to 2007 provided by Beijing Center for Disease Control and Prevention and the meteorological data such as average temperature, average minimum temperature, average maximum temperature, rainfall, rainy days, sunshine time, relative humidity and average wind speed, a multiple stepwise regression would be made with statistical software SAS 9.0. Results The multiple regression co-linearity results showed there was strong linear relationship among average temperature,average minimum temperature and average minimum temperature. The multiple stepwise regression equation was y=0.533 97X2+0.078 14X7-2.673 29X8-2.232 56 (X2, X7 and X8 represented average minimum temperature, relative humidity and average wind speed, respectively). Conclusion The main meteorological parameters closely related to mosquito density were average minimum temperature, relative humidity and average wind speed. The order which affected mosquito density was in turn average minimum temperature, average wind speed and relative humidity
