摘　　要：本文根据重矿物分散流分析和沉积物运移方向的定量统计,研究了珠江日黄茅海河口湾的泥沙来源和运移。重矿物分散流分析表明黄茅海河口湾的泥沙来源除了流域径流来沙外,河口湾周围小河输沙和湾内外岛屿供沙也是不可忽视的组成部分,其中上川岛的SW向来沙是一股重要的泥沙流。在此基础上的泥沙运移方向的定量统计证实了上述分析的正确性和合理性。Analysis of heavy-mineral dispersion flow and statistics of sediment transporta-tional directions were made to probe the source and movement of sediment load in Huangmaohai Bay .which is west of the Pearl estuary. The sediment was largely from the runoff of larger rivers at the head of the bay,while smaller river on the sides of the bay and islands around the mouth of , the bay counted for considerable shares in sediment sources,with the SW-ward sand flow coming from the Shangchuan Island as the largest one. The statistics calculation on sediment transporta-tional directions gave a verification on the accuracy and reasonability of the analysis.
