摘　　要：主要利用2008年5月1-19日四川省142个自动气象站的逐时观测资料,分析了“5.12”汶川8.0级特大地震前后的地面气温。分析结果表明,2008年5月除降水日外,重灾区日平均地面气温比近30年的日平均气温偏高;重灾区主震前后气温整点观测值变化幅度基本不超过±1°C,重灾区处于川西北高原阿坝州负变温区与四川盆地东部正变温区的交界地带。Wenchuan Earthquake occurred at 14：28 on May 12,2008 in Sichuan,China. Based on the data observed by 142 Sichuan automatic meteorological stations from 1 st to 19th May 2008, the characteristics of surface air temperature before and after Wenchuan Earthquake are analyzed in this paper. The results show that the mean daily air temperatures except rainyclays in severe disaster counties are higher than the 30 - year average. The air temperature change from at 14：00 to 15：00 is between - 1 ℃ and 1℃ in severe disaster counties.
