气候变化下的黄河流域极端水文现象特征分析

摘要

In this paper, nearly 50 years meteorological and hydrological data of the Yellow River Basin were used to research the characteristics of climatic variation and extreme hydrological events. The results show that temperature of the Yellow River Basin in the 1980s rose significantly, and the trend of annual rainfall decrease, storm, flood, drought and other extreme hydrological events were more prominent. This research provides great support for scientific planning and water resources optimization scheduling.%利用黄河流域近50年气象水文资料，开展了黄河流域气候变化和极端水文现象特征研究，研究结果表明：20世纪80年代以来黄河流域的气温显著升高，年降水量呈不明显下降趋势，暴雨、洪水、干旱等极端水文现象更加突出，研究成果为科学规划和水资源优化调度提供了有力依据。
