通过杭州湾3个代表性站位的日内连续观测数据，对其冬季表层水体悬浮泥沙质量浓度的逐时变异进行研究，分析不同的潮时、潮型以及风速等因素对悬浮泥沙的质量浓度变化的影响。结果表明：风速较小且稳定时，不同涨落潮时引起的流速变化是杭州湾悬浮泥沙质量浓度变化的主要原因；在风力较大且不稳定时，风力作用引起的泥沙再悬浮可能会导致悬浮泥沙质量浓度变化异常。

The in situ data observed in three representative stations showed that the hourly variability of the suspended sediment concentration of Hangzhou bay surface water in winter was attributed by the variation of tides and winds .The results indicated that when the wind speed was slow and stable ,the velocity change caused by different fluctuation tide was the main cause of the variability of the suspended sediment concentration in Hangzhou bay .However ,when the wind speed was fast and unstable , the suspended sediment resuspension caused by wind may lead to the abnormal variations of suspended sediment concentration .
