Study on the Relation Between the Death Number of Emergency Treatment and the Meteorological Elements in Beijing
The relation between death number of emergency treatment and meteorological elements are analyzed by using the successive regression. The result shows that there are anticorrelation between the total death number of emergency treatment of every month and the monthly mean temperature and between that of every dekad and the mean minimum temperature in the same period and positive correlation between that of every month in fall and winter and the monthly mean atmospheric pressure.The major meteorological element which influence the death number of the cerebral angilogical disease and the circulatory system disease of every month is the monthly mean atmospheric pressure,and the relation between them is of positive correlation. The death number of respiratory system disease and the respiration exhaustion is affected obviously by the mean monthly maximum temperature and the monthly precipitation respectively,and the relation between them is of anticorrelation. All regression equations reflect the character that the death numbers of emergency treatment are largest in winter (temperature is lower ,atmospheric pressure is highest,and precipitation is smallest.) and least in summer (temperature is highest,atmospheric pressure is lower,and precipitation is most).
