摘 要:近年来黄河流域下垫面发生了巨大变化,研究现状下垫面条件下极端暴雨再现后黄河可能的产洪产沙量是目前人们关注的主要问题之一。以1933年8月黄河流域发生的大暴雨为研究对象,分别建立15条小流域在天然和现状下垫面条件下的产洪产沙模型,按照现状下垫面与天然下垫面相比各小流域场次洪水产生的次洪水量和次洪沙量的减少比例,估算现状下垫面条件下1933年8月大暴雨再现后黄河三门峡站的产洪产沙量。研究结果表明:在2种现状下垫面条件下若重现1933年8月大暴雨,预测黄河三门峡站可能产生的次洪水量为25.20亿~25.57亿m^(3),次洪沙量为5.14亿~6.42亿t。In recent years,the underlying surface of the Yellow River Basin has undergone tremendous changes.Researching the possible flood and sediment yield of the Yellow River after extreme rainstorms reappears under the conditions of the underlying surface is one of the main issues that people are concerned about at present.Taking the heavy rain that occurred in the Yellow River Basin in August 1933 as the research object,the flood and sediment production models of 15 small watersheds under the conditions of natural and existing underlying sur⁃faces were respectively established.According to the reduction ratio of sub⁃flood volume and sub⁃flood sediment volume produced by small watersheds flood when the current underlying surface was compared with the natural underlying surface,the flood and sediment yield of the Yellow River Sanmenxia Station after the heavy rainstorm reappeared in August 1933 under the current underlying surface conditions was esti⁃mated.The research results show that if the heavy rain in August 1933 reappears under the two current underlying surface conditions,it is predicted that the secondary flood volume that might be generated at the Sanmenxia Station of the Yellow River is 2.520 billion m^(3)to 2.557 billion m^(3),and the secondary flood and sediment volume is 514 million t to 642 million t.
