以泾河中游彬县至礼泉段的JH-CJC沉积记录的古洪水信息,结合实测洪水和历史洪水资料,比较了泾河流域不同时间尺度洪水序列频率。研究结果表明,将古洪水研究成果加入到历史洪水和实测洪水资料序列中,可大大延长洪水序列的时间长度,提高洪水频率分析的精度,说明河流沉积记录的古洪水信息,对于水利工程建设和防洪减灾具有重要的意义。 Based on the historical flood information recorded by JH-CJC from Binxian to Liquan in the middle reaches of Jinghe River, the flood sequence frequencies of Jinghe River Basin at different time scales were compared with the measured flood and historical flood data. The results show that adding the research results of paleo-floods into historical flood and measured flood data sequences can greatly extend the length of flood sequences, improve the accuracy of flood frequency analysis, and explain the ancient flood information recorded by river sediments. For the construction of water conservancy projects and Flood control and disaster mitigation are of great significance.
