| 摘 要： | 本文利用2003年1月—2012年12月的MSR2臭氧总量月平均资料对四川盆地(28～31°N,104～106°E)、青藏高原(27～37°N,80～95°E)、云贵高原(23～27°N,98～106°E)3个区域的臭氧总量空间分布及变化趋势进行了对比分析。得到了以下结论,四川盆地常年存在臭氧总量最大值,青藏高原次之,云贵高原最低。在2003—2012年这10 a间西南地区臭氧总量总体呈上升趋势,这同全球臭氧总量近几十年的变化趋势相一致,其中上升趋势云贵高原四川盆地青藏高原。西南地区在这十年间分别出现了臭氧总量最小值年(2008年)和臭氧总量最大值年(2010年),其中青藏高原还出现了一个臭氧总量最小值年(2004年)。就臭氧总量季节变化而言,在2003—2012年10 a间西南地区臭氧总量在春季存在最大值,但是青藏高原的臭氧总量在秋季存在最小值,而四川盆地和云贵高原的臭氧总量在冬季存在最小值。

| Abstract: | The temporal and spatial distributions of the total ozone of Sichuan basin (28-31°N,104-106°E), Tibetan Plateau (27-37°N,80-95°E), Yunnan Guizhou Plateau (23-27°N,98-106°E) were contrastively analyzed by using the monthly mean data of the total ozone of MSR2 from January 2003 to December 2012. The conclusions show that Sichuan basin in Southwest China perennially has the maximum of total ozone, the total ozone of Sichuan basin is more than that of Tibetan Plateau, and the Yunnan Guizhou Plateau has the lowest. The amount of total ozone in Southwest China has increased from 2003 to 2012, which is the same to the total ozone of the globe. The rising trend of the Yunnan Guizhou Plateau is larger than that of the Sichuan basin and the Tibetan Plateau. In Southwest China during ten years, a minimum and maximum of annual total ozone exist in 2008 and 2010. The Tibetan Plateau also has the minimum annual total ozone in 2004. In terms of the seasonal average change in total ozone, the maximum of total ozone in Southwest China occurs in spring during the ten years, but the minimum in Tibetan Plateau appears in autumn, while in Sichuan basin and Yunnan Guizhou Plateau, it is in winter. |
