Analysis is made of the relation of air temperature, atmospheric pressure, and precipitation to the incidence rate of Cholera from 1994 to 1998 in Xicheng District, Beijing,using the Spearman rank correlation method and the statistical package SPSS. The results indicate that there is significant positive correlation between the incidence rate and air temperature, nonsignificant correlation with atmospheric pressure and precipitation; the incidence rate of Cholera increases with air temperature. The significance test of the incidence rate and monthly average temperature supports the correlation of incidence rate and air temperature. It is concluded that meteorological impact is one of factors that affect the incidence rate of cholera.
