区划方法在无资料地区水文预报中的应用研究

区划方法是目前国际上解决无资料地区水文预报问题的常用方法,是近20年水文学界热点问题之一。本文通过介绍当前国际应用区划方法解决无资料地区水文预报问题的研究进展、存在问题和应用前景,为国内无资料地区水文模拟研究提供借鉴和参考。文章将区划方法分为3类:临近流域替代法、水文相似流域替代法和回归法。通过文献梳理及案例分析,本文指出各类方法的问题、适用范围及不同资料条件下方法选择。最后,通过对国际上无资料地区水文预报的总结分析,提出我国无资料地区研究亟待解决的5个问题。

Application of Regionalization in Hydrological Forecasting for Ungauged Basins

Regionalization is a common method for prediction in ungauged basins (PUB), and it is one of the research hotspots in recent 20 years. This paper introduced the current international research on regionalization in solving PUB problem, to provide reference for domesti c research. This paper divided re gionalization into 3 categories, namely, regionalization based on spatial distance, regionalization based on hydrological similarity and regionalization based on regression. By literature review and case analysis, the problem and the scope of application has been analyzed. At last, this paper pointed out 5 problems in the PUB in China.
