| 摘 要： | 2003年元月在盛行西北偏北风的情况下,对位于太湖北部的梅梁湾进行了面上湖流调查,发现梅梁湾湾口的湖流较为稳定,以向南流为主,且流速相对较大,最大达8cm/s,梅梁湾西岸有稳定的向北流,而从五里湖口至拖山附近的梅梁湾东线湖水由北向南流动,且在中部附近分为两支,一支向西,再流向北以补偿西岸的向北流,另一支扩散至整个梅梁湾南部,向南流经湾口进入太湖.在梅梁湾东北部,发现有弱辐合中心,该范围内Chl.a和TP、TN的含量明显高于周围水域.从所有点的垂直运动判断,梅梁湾水流以弱上升运动为主,大小为2cm/s以下.从水量平衡分析,以梅梁湾流入太湖为主要特征,水量补给主要来自于北部的五里湖和直湖港及武进港.

| Abstract: | Hydrodynamics in shallow lake has been paid more and more attention to since it has profound effect on sediment resuspension and nutrients transportation in recent years.An investigation to current circulation pat-tern was made in Meiliang Bay,Lake Taihu on19January2003and a conclusion has been drawn that the water at the mouth of Meiling Bay moves to Lake Taihu stably with a peak speed8cm/s,and the water lo-cated along the west shore moves toward the north and it is in opposite style on the east side.The current along the east shore branches off to the west to compensate for mass loss and to the south to flow into Lake Taihu.An convergence center was found in the northeast area of Meiling Bay with high nutrients concentra-tion.The water ascends in most areas and flows into Lake Taihu totally with supply fromthe rivers located a-long shore and Lake Wuli. |
