摘　　要：2009年7月22日,我国长江流域能很好地观测到一次千载难逢的日全食现象,且重庆是一个非常好的日全食观测点。作者观测了重庆地区7月21日及22日两天的室外气象数据(太阳辐射,空气温度,相对湿度等),基于实验观测数据,分析和探讨了日全食对室外热环境的影响。日全食当天,室外气温和地表温度随太阳辐射强度的减小而减小,空气温度降幅为2.4℃。对比两天的室外气温,日全食所引起的空气温降达到4.6℃。There was a very good observation area in Chongqing for the total solar eclipse along the Changjiang river on 22 July,2009.Through the experiments,the outdoor meteorological data（solar radiation,air temperature and relative humidity） were observed and recorded on 21 July and 22 July.Based on the experimental observation data,the effect of thermal environment in Chongqing area was to analyzed and discussed.Experiment indicates that the reduction of air temperature and surface temperature resulted in the decrease in the solar radiation intensity,and the amplitude of the air temperature change is 2.4 ℃ during the total solar eclipse.Compared with the two days＇ air temperature,the amplitude of the air temperature change reached 4.6 ℃ on account of the total solar eclipse.
