| 摘 要： | 利用四川西南地区1960至2007年7个气象观测站点的逐日气温资料,分析了该地区日平均气温稳定通过0、5、10℃的初日、终日、持续日数、积温的年际变化、空间变化特征。结果发现,四川西南地区≥0℃、≥5℃、≥10℃的积温变化均呈增加趋势;在这48年里,1998～2007年是热量和持续日数增加幅度最大的时期,其中四川西南的东、西部地区≥0℃、≥5℃、≥10℃的平均年积温增加幅度最显著,中部的西昌平原地区次之,盐源地区增加最少;≥5℃的初日提前、终日推迟、持续日数增加最显著;在空间上,东、西部地区≥5℃、≥10℃的持续日数增加最显著。

| Abstract: | By using the observation data from 7 meteorological stations in the southwest of Sichuan from 1960 to 2007, the changes of the starting date, ending date, duration days and the accumulated temperature above 0 ℃, 5 ℃, 10 ℃ in different space and different years were analyzed. It was found that there were increasing trend on the accumulated temperature above 0 ℃, 5 ℃ and 10 ℃ in the southwest of Sichuan. In the 48 years, thermal resource and duration days most remarkably increased from 1998 to 2007, especially the accumulated temperature above 0 ℃, 5 ℃ and 10 ℃ rose with the highest range in the east and west of the southwest of Sichuan, in the Xichang plane was taken second place, and in Yanyuan area rose with the lowest range. The starting date of the accumulated temperature above 5 ℃ was earlier, it's ending date was later and it's duration days were rising than the accumulated temperature above 0 ℃ and 10 ℃. In the space, duration days of the accumulated temperature above 5 ℃ and 10 ℃ most remarkably increased in the east and west of the southwest of Sichuan. |
