摘　　要：扼要介绍了 2 0世纪 80年代初发展起来的 ,被誉为数学“显微镜”的信号分析新方法———小波分析。在此基础上 ,综述了小波分析在水文水资源系统中的应用研究现状。展望了小波分析在该领域的未来研究趋势和发展方向。将小波分析引入水科学 ,不但拓宽了应用范围 。A new mathematical method, wavelet analysis which is called mathematical microscope, is introduced Then the state of application and research of wavelet transform is introduced in the hydrology system, including four aspects: (1) time frequency multiple time scales analysis of hydrological time series, (2) change properties of hydrological time series, (3) forecasting in hydrology, and (4) simulating of hydrological process Finally, some trend and directions for future studies in hydrology and water resources are presented
