| 摘 要： | 泥沙积聚再悬浮是长江口浑浊地带形成的主要机理.促使泥沙积聚有径流潮流相互作用和盐淡水交汇混合两种机制,前者形成潮汐浑浊带,后者形成盐水浑浊带长江口浑浊带是具有两种不同机制的盐潮复合浑浊带.长江口浑浊带在不同时间、不同地点表现出不同的特点.

| Abstract: | The sediment accumulation and the accumulated sediment resuspension in the mouth-bar area under the hydrodynamic environ ment of the Changjiang Estuary are the major mechanism of the gturbidity maximum formation. The sediment accumulation has both mechanismsof the runoff and the tidal current interaction and the salt and fresh-water mixing, the former forms the tidal acidity, and the latter formsthe salt water turbidity maximum. The turbidity maximum of the Changjiang Estuary belongs to co-turbidity maximum with both tide and saltmechanisms. |
