太湖地区贡湖湾生态修复区围隔系统消浪挡藻技术研究

摘要

通过在贡湖湾生态修复区与外太湖连接处7#桥外侧设置双层围隔消浪挡藻系统,结合导流门技术,研究该系统的消浪、挡藻和导流效果.结果表明,该系统具有良好的消浪挡藻效果,波浪消减率达到近30％,藻密度下降幅度达到80％以上,导流效果明显.%Double barricading wave and algae system was established beside the 7# bridge in the connection area of Gonghu Bay Ecological Restoration Area and outer Taihu Lake.Based on diversion gate technology and the characteristics of Gonghu Bay wind field,the lake waves were reduced,the exogenous cyanobacteria was blocked to restoration area.Barricading wave and algae system was mainly composed of wave barricading,algae barricading,and controlled diversion gate.Results showed that the wave reduction rate reached 30％,and algae density reduced by more than 80％.Thus,the efficiency of diversion was significant.
