水文相似和尺度分析

水文尺度分析是当前水文科学的热点之一，为国内外水文学者关注和重视。综合论述以水文相似为基础的水文尺度分析，较详细地介绍了水文现象中普遍存在的三种水文相似——统计相似、自相似和动态相似，并根据已有的研究成果说明这些相似在水文中的应用。重点指出，水文相似和尺度分析紧密相联，进一步深入探讨水文现象的各种相似性非常必要。

Hydrologic Similarity and Scale Analysis

Hydrologic analysis in scale is one of the major issues of hydrology at the present time. This issue has been concerned and taken seriously. This paper deals with the hydrologic analysis in scale based on hydrologic similarity. It is introduced in more detail that three kinds of hydrologic similarity universally in hydrologic phenomenon which are statistic similarity, self-similarity and dynamic similarity. The application of these similarities to hydrology is demonstrated based on the obtained results in the past. The close relation of hydrologic similarity with scale analysis is specifically pointed out. It is necessary to explore deeply all kinds of similarity in hydrologic phenomenon.
