目前,准确估算河流泥沙通量是实施河流泥沙总量控制的前提。以新疆北疆河流1980年的含沙量资料为基础,基于负荷历时曲线方法计算泥沙通量,分析泥沙通量的年际变化及其影响因素,探讨基于负荷历时曲线通量估算的不确定性、适用性。得出基于负荷历时曲线的通量估算方法能较准确估算新疆河流泥沙通量,可为新疆河流泥沙通量的研究提供新思路,为泥沙防治工作提供理论依据,具有一定的学术意义和应用价值。
At present, accurate estimation of river sediment flux is the premise of implementing total control of river sediment. Based on the data of sediment concentration in the Beijiang River in Xinjiang in 1980, the sediment flux was calculated based on the load-duration curve method. The interannual variation of the sediment flux and its influencing factors were analyzed, and the estimation of the curve flux based on the load duration Certainty, applicability. It is concluded that the flux estimation method based on load duration curve can accurately estimate the sediment flux of Xinjiang river sediment and provide a new idea for the study of sediment flux in Xinjiang River. It provides a theoretical basis for sediment control and has certain academic significance And application value.
