摘要
从不同时间尺度分析了黄河入海口的海洋动力输沙能力,阐述了黄河入海流路选择与海洋动力输沙能力的关系。结果表明:黄河口海洋动力输沙能力与流路安排紧密相关,黄河河口海洋动力输沙能力应从宏观、中观、微观三重特性上去把握,三者是相互对立统一的辩证关系。在黄河下游改道入海口选择时,应考虑渤海或黄海的近岸输沙能力;进行黄河三角洲的流路规划时,应分析各流路多年平均海洋输沙量;在确定清水沟流路组合方案时,应分析海洋动力的微观输沙能力。
Sediment transporting characteristics of ocean dynamics in the Yellow River estuary were analyzed in different time scales, then relation- ships of flow path selections and sediment transporting characteristics of ocean dynamics were studied. Results show that sediment transporting capaci- ties of ocean dynamics are closely related to flow path selection. Sediment transporting characteristics can be understood by macro, mid and micro in time scales, which are unity of opposites. To select lower roaches and estuaries of the Yellow River, sediment transporting capacity of the Bohai Sea and the Yellow Sea should be considered. To plan the flow path of the Yellow River delta, the average sediment transporting capacity of each path should be analyzed. To determine the combination scheme of Qingshuigou path, sediment transporting capacity of micro time scale should be studied.
