摘要
本文采用南太子河流域南甸站1958-2022年的年降雨径流数据,通过Mann-Kendall趋势分析法分析近65年来流域降雨径流的趋势及突变点,应用EEMD分析方法进行多时间尺度分析,提取出该流域降雨、径流的年际频率特征,为该流域防汛、抗旱、水利规划提供依据。
In this paper,annual rainfall and runoff data from Nandian Station in the South Taizihe Basin from 1958 to 2022 were used to analyze the trend and mutation points of rainfall and runoff in the basin in recent 65 years through Mann-Kendall trend analysis method,and multi-time scale analysis was carried out using EEMD analysis method to extract the interannual frequency characteristics of rainfall and runoff in the basin.It provides basis for flood control,drought resistance and water conservancy planning in river basin.
