北京地区急诊死亡与气象要素关系的探讨

Study on the Relation Between the Death Number of Emergency Treatment and the Meteorological Elements in Beijing

对北京急诊死亡人数与气象要素进行了逐步回归分析，结果表明：逐月、旬死亡人数与同期平均气温或平均最低气温呈负相关，与平均气压呈正相关。影响脑血管和循环系统疾病逐月死亡人数的主要气象因子为月平均气压，呈正相关。呼吸系统疾病和呼吸衰竭逐月死亡人数分别受月平均最高气温和月降水量的影响，呈负相关。所有回归方程都反映出冬季（气温低、气压高、降水少）死亡人数多，夏季（气温高、气压低、降水多）死亡人数少。

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).
