中文摘要: 为深入了解中国西南5省ET_0演变规律,利用19542013年广西、重庆、云南、贵州、四川5个省市119个站点逐日地面气象资料,采用FAO-56推荐的Penman-Monteith公式计算各站点逐日ET_0,并使用Mann-Kendall检验、 Morlet小波分析和GIS反距离加权插值定量分析ET_0时空变化特征。结果表明,19542013年西南5省ET_0多年平均值为855 mm,波动范围为819~901 mm,年均ET_0总体呈下降趋势(倾向率为-1.5 mm/10 a),在春、夏、秋、冬季也均呈下降趋势(倾向率分别为-0.4、-0.7、-0.3、-0.1 mm/10a),分别占全年的26.7%、46.7%、20%、6.6%;西南5省ET_0多年平均值分别以26 a、12 a、5 a为第1、第2、第3周期进行增大-减小交替变化;19542013年,西南5省年均ET_0空间分布总体表现为南部大于北部,云贵高原西部和广西地区明显大于四川盆地和云贵高原东部,四川盆地相对最小,川西高原南部和云贵高原东部地区相对最大;西南5省ET_0在春、夏、秋、冬季空间分布较高值区分别为云贵高原西部、四川盆地和云贵高原东部、广西地区、云贵高原西部,较低值区分别为四川盆地、云贵高原西部、四川盆地和川西高原东北部、四川盆地和广西地区。
英文摘要: For an in-deep analysis of temporal and spatial changing characteristics of ET_0 in the five provinces of Southwest China(Guangxi Zhuang Autonomous Region, Chongqing Municipality, Yunnan Province, Guizhou Province, Sichuan Province), daily climatic data in 119 meteorological stations were used to calculate ET_0 using Penman-Monteith(P-M)equation by FAO. In addition, Mann Kendall rank correlation, Morlet wavelet method and interpolation of GIS were applied to a quantitative analysis of the spatial-temporal variations characteristics of ET_0. Results showed that the annual mean ET_0 of the five provinces of Southwest China was 855 mm, the fluctuation range was 819~901 mm over the past sixty years, and the ET_0 had a decreasing trend with a rate of 1.5 mm per decade for annual series. The descent speeds were -0.4 mm/10a, -0.7 mm/10a, -0.3 mm/10a, -0.1 mm/10a in spring, summer, autumn, winter, which accounted the annual decreasing trend for 26.7%,46.7%,20%, 6.6%. The annual ET_0 of the five provinces of Southwest China existed anincrease- decreasealternating change with periods of 26, 12 and 5 years. 26, 12 and 5 years were the first, second and third periods respectively; During the past 60 years, the the annual mean ET_0 in the south was greater than that in the north, those in western Yunnan-Guizhou plateau and the Guangxi area were significantly greater than those in the Sichuan basin and eastern Yunnan-Guizhou plateau. Sichuan basin was relatively minimal, those in the south of western Sichuan plateau and eastern Yunnan-Guizhou plateau area were the relatively largest; In spring, summer, autumn and winter, the higher values were found in western Yunnan-Guizhou plateau, Sichuan basin and eastern Yunnan- Guizhou plateau, Guangxi area, wastern Yunnan-Guizhou plateau, the lower values were found in Sichuan basin, western Yunnan-Guizhou plateau, Sichuan basin and the north- east of western Sichuan plateau, Sichuan basin and Guangxi area.
