摘　　要：采用小波分析和有序聚类分析法分别对柘林水库的年最大洪峰、年降雨量、年径流量进行分析。研究结果表明,水库建成后流域年最大洪峰值和年径流量呈增大趋势,年降雨量基本无变化。In the paper, multi-scale wavelet and ordered cluster segmentation analysis methods were used to study the changes of annual maximum flood peak, annual rainfall and annual runoff, respectively. On the conclusion that all periods of hydrology cycle factor are changed, maximum annual flood peak and annual runoff became larger after reservoir construction. However, there is no effect on annual precipitation.

关 键 词：周期分析 年径流 洪峰 小波分析 聚类分析
