摘　　要：分析了京津冀地区7个代表城市站1999年实行"五一"和"十一""黄金周"长假期以来地面气温变化特征。采用7个城市站1961—2007年平均气温、最高气温和最低气温逐日观测资料,主要比较分析了长假7天的平均气温与长假前后各7天平均气温的差异。结果表明,实行"黄金周"长假以来,7个城市"黄金周"期间的平均气温、最高(低)气温一般有较明显的变化。平均气温在"五一""黄金周"期间有明显上升趋势,"十一""黄金周"期间则有下降趋势;"五一""黄金周"期间平均最高和最低气温均有明显增加,最高气温增加更显著,而"十一""黄金周"期间最高气温变化不大,最低气温则有较显著降低。Using the meteorological data of seven cities in Beijing,Tianjin and Hebei Province,the variation of surface air temperature during the long vacations of International Labor Day and National Day was analyzed to determine the climate effect of＂Golden Weeks＂beginning from 1999.Results show that mean and maximum temperature significantly change during the long vacations of＂Golden Weeks＂.An apparent increasing trend of average air temperature is found during the seven-day vacation period of International Labor Day,whereas average air temperature shows a decreasing trend during the seven days of National Day.During the long vacation of International Labor Day,both mean maximum and minimum temperatures significantly increase with a larger increase in maximum temperature.Mean maximum temperature shows weakly change in the vacation of National Day,whereas the minimum temperature significantly decreases during the same period.
