摘要
基于1950—2013年的黄河水文泥沙资料,系统研究了黄河实施调水调沙以来入海泥沙在通量、粒度组成和时间分布上的变化特征,揭示了调水调沙影响下黄河入海泥沙的变化趋势。在2002年黄河实施调水调沙以来,6—11月平缓均衡的持续性高水沙量取代了调水调沙之前7—10月峰值尖瘦的汛期特征,汛期与非汛期差异减小,入海水沙通量的季节性特征显著改变。随着调水调沙的逐年实施,河床泥沙颗粒粗化,临界起动功率不断增大,而调水调沙期间的径流量峰值基本稳定,径流对下游河床冲刷效率不断降低,导致入海泥沙通量持续降低、泥沙颗粒变细。可以预见,黄河河口的淤积将会大大减缓,入海的泥沙将更多地沉积在远离河口的区域,维持河口三角洲叶瓣冲淤平衡的临界泥沙量将会加大。
