摘要
阐述了小波分析在水文预报中的应用现状,讨论了小波消噪在水文序列中的中的重要性,并介绍了基于小波消噪的偏最小二乘回归模型,得出消噪后的水文序列的相依性会大大提高,能更好地为建立水文预报模型奠定基础。
This paper introduced present situation of wavelet analysis application in hydrological forecasting,mainly discussed the importance of wavelet denoising in hydrological sequence and introduced partial least squares regression model based on wavelet denoising,the dependence of the denoised hydrological sequence could greatly improved,which was better for laying the foundation of the establish prediction model.
