摘要: 风浪引起沉积物再悬浮会直接影响水体光照条件,促进沉积物中污染物的释放,对湖泊生态系统的构建产生着重要影响。采用已发表数据验证了风浪要素和风浪切应力经验计算公式在浅水湖泊中的适应性,并从浅水湖泊风浪扰动机理出发,提出了临界起动应力简化计算方法和适用条件并加以验证。最后,基于简化模型和风致再悬浮影响评估方法研究了风浪对金湖水生态修复的影响,结合生态围隔、综合底质改良剂和复合微生物菌剂等综合措施,恢复金湖沉水植物150万m2。研究结果可用于评估风浪对浅水湖泊沉积物再悬浮的影响,为浅水湖泊水生态修复、内源污染治理工程设计提供理论参考。Abstract: The resuspension of sediment caused by wind waves will directly affect the lighting condition of lake water, promote the release of pollutants in sediment, and have a big impact on the construction of the lake ecosystem. In this paper, the published data validation was used to verify the adaptability of the empirical calculation formula of wind wave elements and wind wave shear stress in shallow lakes. Based on the simplified model and the wind-induced resuspension impact assessment method, the impact of wind waves on the ecological restoration of the Jinhu Lake water was studied. By comprehensive measures, such as ecological enclosure, comprehensive substrate improvers, and composite microbial agents, 1.5 million m2 of submerged plants were successfully restored. This method can be used to assess the impact of wind and waves on sediment resuspension in shallow lakes, and guide the design of water ecological restoration and endogenous pollution control projects in shallow lakes.
