摘要
基于广西岩溶区流域澄碧河水库1963-2014年最大洪峰流量序列,采用水文变异诊断系统中的多种检验方法对序列的趋势和突变进行综合分析,并运用Morlet小波分析法对其周期性进行研究。结果表明:岩溶区澄碧河水库年最大洪峰流量序列整体呈不显著下降趋势,年均下降速率为6.04 m^3/s;序列于1979年发生以跳跃形式为主的变异;1985年之前,序列的主周期为15 a,次周期为8和28 a,1985年之后无明显周期性规律。
Based on the annual maximum peak discharge series from 1963 to 2014 in Chengbi River in karst basin of Guangxi, various test methods of Hydrological alteration diagnosis system are used to analyze the trend and mutation, and Morlet wavelet method is used to analyze periodicity. The results show that: the annual maximum peak discharge series has an insignificant declining trend, whose rate is 6.04 m^3/s per year, and mutation occurred in 1979.
