摘　　要：为研究小波理论在枯水特征值分析中的应用,介绍了小波分析理论,包括基本小波数、小波变换系数与小波方差,并用该理论研究了西北江三角洲的枯水特征,识别了马口、三水站和思贤滘水文序列周期、突变情况。结果表明小波分析可以有效识别水文系统的多间尺度特性。For the study of wavelet theory in the application of low flow characteristic value analysis,this papermainly introduces the basic theory of wavelet analysis,including wavelet functions,wavelet transform coefficientsand wavelet variances,applies the theory to the study of the low flow characteristics in Northwest River Delta,andrecognizes the cycles of hydrological sequence and mutations in Makou Station,Sanshui Station,and SixianjiaoStation.The results show that wavelet analysis can effectively identify the multiple time scale characteristics ofhydrological system.
