摘　　要：利用太湖二维水动力模型,分析了不同风场条件下的太湖西部湖流特征以及滨岸带冲刷深度。研究结果表明,太湖湖流的冲刷会对滨岸带产生不利影响,尤其在东风、南风、东南风驱动的情境下,湖流对滨岸带的侵蚀最为严重。通过对滨岸带进行基底修复,可以防止湖流的冲刷侵蚀。Based on the two-dimensional hydrodynamic model of Taihu Lake,the characteristics of lake flow and the erosion depth of littoral zone in the west of Taihu Lake under different wind conditions are analyzed.The results show that the erosion of lake current in Taihu Lake will have adverse effects on the littoral zone,especially under the situation of east wind,south wind and southeast wind,the erosion of lake current on the littoral zone is the most serious.The erosion of lake flow can be prevented by basement restoration of littoral zone.
