摘要
洪泛和河道变迁是历史时期黄河下游频繁发生的最重大自然灾害事件,也是中原地区人民所面临的深重灾难.基于历史文献资料记载和前人研究的成果,对历史时期黄河下游洪泛和河道变迁的原因及其对自然环境和经济社会所造成的影响作分析.结果表明,黄河下游频发的洪泛和河道决口事件是多方面因素共同作用的结果,自然因素主要包括气候、泥沙淤积、地形等,人类活动则加速了黄河下游洪泛、河道变迁的发生.黄河下游洪泛现象与河道变迁关系密切,河道决溢改道大部分也是洪泛的结果.
Frequent flooding and avulsion are the main natural disasters in the lower reaches of the Yellow River during the historical period,which may have exerted traumatic impacts on human livelihood in this area.Based on the synthesis of published records and historical documents,the causes about flooding and river course displacement and their impacts on natural environment,economy,and society in the area during different historical periods are studied.It appears that the frequent disasters in the area are the result of the complex interactions of many factors.The natural factors mainly include climate,sediment deposition,and topography.Human activities also may have accelerated these processes.In addition,the flooding phenomenon is closely associated with river course displacements in the area and the avulsion is also the result of flooding.
