摘要
基于唐乃亥水文站1956～2009年实测年径流量和年输沙量序列,应用协整分析和集对分析方法量化探讨了黄河源区水沙变量之间的波动关系。结果表明,年径流量与年输沙量之间存在协整关系;黄河源区年径流量和年输沙量波动的同一度最高,对立度最小且仅为0.02;黄河源区水沙变化具有较稳健的同步波动关系。
Based on the annual measured runoff and sediment time series from 1956 to 2009 at the Tangnaihai gauge station,cointegrated analysis and set pair analysis methods are applied to research fluctuation relationship between runoff and sediment at the source region of the Yellow River.The results show that there exists cointegrated relationship between annual runoff and sediment series;the similarity value of the two series is the most highest and the counter value is the smallest as only 0.02;there is robust synchronous fluctuation relationship between runoff and sediment series in the source region of the Yellow River.
