摘要
采用Mann-Kendall法(M-K法)对响洪甸流域1951年~2022年降水量进行分析,采用小波分析的方法对M-K法分析结论进行验证。结果表明,采用M-K法与小波函数能够正确地反映响洪甸水库流域降水序列的突变性和周期性规律,可为其他流域降水系列特征分析研究提供借鉴。
The Mann-Kendall method(M-K method)was used to analyze the precipitation of Xianghongdian Basin from 1951 to 2022,and the results of M-K analysis were verified by wavelet analysis.The results show that M-K method and wavelet function can accurately reflect the variability and periodicity of precipitation series in Xianghongdian Reservoir basin,which can provide reference for the analysis and study of precipitation series characteristics in other basins.
