摘  要：
柳河是东北地区泥沙问题最为严重的河流之一,该文分析了流域水沙运移特征,在此基础上建立起流域16年的沙量平衡关系,分析了流域产沙、沉积特征及沉积的分布格局。研究表明,53.5%的悬移质泥沙沉积在河道中,其中,87.9%沉积在闹德海至彰武之间;对流域上游产水、产沙与流域内泥沙沉积及流域产沙之间的关系进行了耦合分析,丰富了沙量平衡计算的内容,并可对深入认识流域泥沙发展趋势及泥沙治理提供参考。

摘  要：
Liuhe River has the most sediment concentration in the Northeast of China, while sedimentation is the most serious problem in the river. The water and sediment characteristics of Liuhe River and a mass budget for the suspended sediment for this river were established in a period of 16 years. The approach consisted of analyzing the amount of sediment contributed by the different tributaries and the sediment storage in different reaches, through the data observed by 6 hydrometric stations of Liuhe River. The findings indicate that nearly 53.5% of the suspended sediment coming from upstream was stored in the riverway, and 87.9% of the deposited sediment stored in the sector stretching from Naodehai to Zhangwu. Further study on the coupling relationship between the runoff, soil erosion upland, the sediment yield from the outlet and the sediment storage in channel was conducted, which can be used to estimate the tendency of variation in the sedimentation of the lower Liuhe River and sediment yield from this basin.
