摘要:
采用1951年至2010年贵州省19个台站平均气温和日照时数逐日数据,统计了其年平均值,运用Mann-Kendall突变检验法、小波分析法、滑动平均法和线性趋势比较法等,并统计其气候倾向率,来分析贵州省平均气温和日照时数随时间和空间的变化特征。结果表明:贵州省年平均气温呈上升趋势,气温的分布在全省呈东南向西北降温态势;全省的日照时数呈现先上升后持续减少,近10年来又回升的趋势,在全省的分布为自西南向东北减少的态势。

Abstract: Based on the time series of daily average air temperature and sunshine duration of Guizhou Province from 1951 to 2010, the average air temperature and annual sunshine duration was calculated by using the methods of Mann-Kendall abrupt change test, wavelet analysis and moving average method to analyze the climatic trend rate and saptial-temporal characteristics of temperature and sunshine duration of Guizhou Province. The result showed that, the average air temperature of Guizhou has witnessed a continuing rise and the air temperature of the south-east part is higher than the north-west part. The sunshine duration of Guizhou climbed in the 1960s and started to decline since 1970s. However, the sunshine duration showed an increasing trend in the past 10 years. Different with the spatial distribution of air temperature, the sunshine duration of southwest area is more than the north-west area.
