摘要:

利用2009—2012年北京市467例中暑病例与同期9个气象要素资料和当日及前期1—4 d累积平均气象要素共45个气象因子,采用相关分析法分析北京夏季中暑发病人数与气象因子之间的关系|采用多元线性回归和非线性拟合方法构建了改进的北京中暑气象预报模型,选取拟合优度较好的模型对中暑人数进行回代及预测检验,并与现用模型进行对比。结果表明:气温是引发北京夏季中暑的决定性因子|气温、水汽压、气压及降水的两日累积效应均高于当日效应,表明气象要素的连续累积作用对人体中暑影响较大|建立的中暑预报模型具有较好的历史拟合及预测效果,中暑等级划分较合理,对北京市中暑气象等级预报服务和公众有效防范中暑有实际的指导意义。

Abstract:

 Based on 467 heatstroke cases, daily meteorological data and 1-4 days’ accumulated meteorological elements before heatstroke day from 2009 to 2012 in Beijing (sum 45 meteorological factors), relationships between heatstroke incidence and meteorological factors were analyzed by a correlation method. Improved forecast models of heatstroke were established by methods of a multiple linear regression and a nonlinear fitting, and the better model was selected to back substitution and verification for number of heatstroke patients. Also, this model was compared with the current used model. The results show?that temperature is a dominant factor causing heatstroke in summer in Beijing. Cumulative effects of temperature, vapor pressure, air pressure and precipitation in two days have a greater impact on heatstroke. In addition, new models have better fitting and forecasting effect for heatstroke, so is the grades of heatstroke. Thus, the models are of indicative to forecast heatstroke grades and prevent heatstroke.
