摘要
对小波变换的基本理论和小波分析(多分辨分析、小波包分析)方法做了简要的阐述,介绍了国内外当前小波理论在不同领域应用研究现状,结合长江111年的水文资料,分析了小波技术在水文预报预测中的应用,研究结果表明小波分析用于水文时间序列趋势分析是合理可行的。
We briefly introduce the wavelet analysis theory and wavelet transform methods (multi - resolution analysis, wavelet packet analysis), analyze its status quo of development in different aspects at home and abroad, and discuss its applying prospect to hydrological trend forcast. The study based on the gauged 111 years hydrological data of the Yangtze River, the results show that the mode is feasible.
