气候变化下极端水文事件的研究进展

气候异常变化导致洪涝灾害、干旱等极端水文事件的发生及其增加的水灾害风险正成为人类生存所面临的重大挑战。近年来，开展气候变化背景下流域极端水文事件的变化趋势、发生机理及其对气候变化的响应与预测研究正逐渐受到国内外众多学者的关注。本文从极端水文事件的定义、研究方法、水文极值分布函数、观测事实及模拟研究等方面分析评述了极端水文事件问题的研究现状和研究成果。在此基础上，讨论了研究现状存在的问题并对该领域未来研究方向进行了展望。

Progress in the Study of Extreme Hydrologic Events Under Climate Change

Extreme hydrologic events such as floods and droughts caused by abnormal climate change and increased risks of water disasters are becoming the major challenges to the survival of the people survival.In recent years,the research on the change trend,mechanisms,response and prediction of the climate change of the extreme hydrologic events in basins under climate change is drawing more and more attention from the scholars at home and abroad.This paper begins with the definitions of extreme hydrologic events,an...
