摘要: 论述了椒江河口粘性细颗粒泥沙洪、枯季及大、小潮悬沙浓度分布.椒江河口水体高度混浊,近底层悬沙浓度可达71kg/m3以上.在河口最大混浊带,小潮期水体层化现象明显,悬沙浓度垂向分布呈三层结构,即活动悬沙层、泥跃层和浮泥层.泥跃层是水体中悬沙浓度分布剧变层,梯度大.在河口咸、淡水互相作用下,悬沙浓度大于3kg/m3、盐度在4～16及水流速度中等的条件下泥跃层发育.Abstract: Water is higher turbidity and turbidity maximum occurs in the Jiaojiang Estuary.Typical concentration profile is often present in turbidity maximum.There is three order of magnitude range in concentration from the surface to the seabed,i.e.mobile suspended layer,lutocline and fluid mud.It is noted that three layers in concentration vertical profile develops the most clear during neap tide in winter.
