摘要
利用4种数学方法——M-K检验法、Spearman检验法、滑动平均法和小波分析,对和田绿洲实测气温序列进行趋势分析。结果表明,和田绿洲的年、夏、秋、冬季平均气温序列均存在显著的递增趋势;经对比分析不同方法的优缺点,推荐小波分析与传统方法结合分析时间序列的趋势变化。
4 me thods--M-K test, Spearman test, running mean method and wavelet analysis are used to analyze the trend change of the temperature series from Hotan Oasis. The analysis results show that annual, summer, autumn, and winter temperature series have an remarkable increasing trend in Hotan Oasis. Compared with the strong and weak points of 4 methods, the combination of the wavelet analysis and the conventional methods is recommended to analyze the trend of time series.
