| 摘 要： | 风浪是影响浅水湖泊物理生境环境重要的水动力要素之一。基于滆湖实测风浪数据, 建立了滆湖风浪模型, 验证结果表明模型可以较好模拟滆湖风浪随风场变化情况。在此基础上开展滆湖北部水域在人工地形重塑工程实施后的风浪变化情况分析。结果表明, 不同季节盛行风下, 风浪强度和湖底扰动强度均有一定程度的衰减, 这有利于水体透明度和水底光照条件的改善。风浪强度的衰减使得具有有利于水生植物生长与发育风浪条件的水域面积显著扩增。人工地形重塑的实施, 有利于滆湖北部水域水生植被物理生境环境改善, 从而为滆湖北部水域水生植被的修复提供较好的环境支撑, 也为其他浅水湖泊地形重塑工程的实施提供借鉴。

| Abstract: | Wind-wave is one important hydrodynamic factor that affect the physical habitat environment of shallow lakes. A wind wave model was established based on the measured wind wave data in Gehu Lake between Wujin and Yixing, Jiangsu, South China. The verification results indicate that the model can better simulate the changes of wind waves as a function of wind field, based on which the changes of wind-wave condition in the northern part of Gehu Lake after the implementation of the artificial terrain remodeling project were analyzed. Results show a certain degree of attenuation in the wind-wave intensity and the disturbance intensity under the prevailing winds in different seasons, which was conducive to the improvement of water transparency and underwater lighting conditions. The attenuation of wind-wave intensity favored the water area with good wind-wave conditions for better growth and quick development of aquatic plant. The implementation of artificial terrain remodeling project had improved the physical habitat environment of the northern part of Gehu Lake, providing a good support to the restoration of aquatic vegetation, and a reference for the implementation of terrain reshaping projects in other shallow lakes. |
