中文摘要：

变异点识别在区分气候变化和人类活动对水文过程的影响中具有十分重要的作用。近几十年来，国内水文序列变异点的研究逐渐发展，从最早的使用单一方法发展到由多种方法组成的水文序列变异点诊断系统和对部分方法的改进。同时，各种方法在中国各主要流域得到广泛应用，但是使用的方法不同，水文序列时间年限不同，得到的变异点的结果也不完全一致。本文将目前普遍采用的方法及在各流域的应用成果进行了系统总结，为今后水文序列变异点的方法改进及其在流域中的应用发展提供参考。

英文摘要：

Detecting abrupt changes in hydrologic sequences plays an important role in discriminating the impacts of climate change and human activities. In recent decades, researches on abrupt changes of hydrologic sequences have advanced greatly in China from using only one method in the earliest stage to applying diagnosis system of multiple methods and improved methods in the study in the late stage. Different results were given by studies using different methods and/or different time series of hydrologic sequences in the same drainage basins. In this paper, the theories of methods determining abrupt changes in hydrologic sequences and their application in the main watersheds in China are reviewed in order to provide reference for further development of these methods and their applications.
