摘要： 根据渭河流域下游历史时期以来的洪水灾害资料，统计分析170 BC-1992 AD近1 700多年洪水灾害的发生规律。结果表明：从170 BC-1992 AD渭河下游发生的有文字记载的洪水灾害约243次，其中，630 AD之前的洪水灾害发生较少，630 AD之后增多；从1920 AD开始，发生洪水越来越频繁，而且频率在波动中不断升高；1960 AD以后略有下降。根据洪水灾害发生频率，将所研究的时期分为7个阶段，并对每个阶段洪水灾害的发生与当时流域环境演变关系进行了分析，结果表明，历史时期以来环境的改变与洪水灾害的发生有直接关系。因此，加强生态与环境建设，对于当地的防洪减灾具有重要的意义。

Abstract: Flood disasters have occurred for several times in the lower reaches of the Weihe River since recent 30 years and resulted in enormous destruction. It is more and more necessary to deeply research the occurring laws of flood disasters in the study area. In this paper, the change in flood disasters during the period from 170 BC to 1992 AD was analyzed based on the historical flood disaster records in the lower reaches of the Weihe River. The results show that 243 flood disasters were recorded in the lower reaches of the Weihe River, in which they occurred less frequently before 630 AD but more frequently after that. From 1920, flood disasters occurred more and more frequently, but they reduced to some extent  after 1960. According to the historical data, fluctuation of the occurring frequency of flood disasters could be divided into 7 periods, the relationship between flood disasters and entironment evolution was analyzed, and the results show that the occurrence of flood disasters during the historical periods was directly related to the entironment evolution in the drainage basin. Therefore, it is very important for reducing flood disasters to intensify the entironment construction in the drainage basin.
