摘　　要：The results of the suspended material measurement in the Huanghe River Estuary show that the silt movement in the estuary is different during summer and winter. The centric water-mass in Bohai Sea enters the Laizhou Bay, which makes the fresh water occupy the head of Laizhou Bay and prevents the silt from spveading to the sea.The disturbing of wind in winter makes the sediment resuspend which results in the high content of suspended materials in the water. The distribution of suspended materials and salinity in summer indicate that because of its own momentum, the silt from the Huanghe River will go ahead out of the river mouth and the effect of centric water-mass in the middle Bohai Sea is relatively small in summer. The distributions of suspended materials in the mid and bottom layer water during different seasons show that the primary direction of the siltl movement in the estuary is towards NE, whice coincides with the movement of residual current.Our paper also presents the size distribution of suspended materials.According to the data, we consider that the silt from Huanghe River moves mainly in the surface layer and the Huanghe River Estuary belongs to weak mixing estuary.The results of the suspended material measurement in the Huanghe River Estuary show that the silt movement in the estuary is different during summer and winter.
