摘要
随着海洋渔业资源的衰退和海洋生态环境的破坏,人工鱼礁技术得到迅速发展,成为海洋牧场建设的重要组成部分。采用CJK3D-WEM建立了吕泗渔场组合型人工鱼礁群二维潮流数学模型,模拟了礁群实施后周边海域水动力的变化,并通过分析海床泥沙活动性探讨了礁群的稳定性。研究结果表明:礁体的阻挡作用会在礁体后方形成了一个梭状的缓流区域,离礁体越近流速越小;多礁体之间形成了流速渐次变化的生物和鱼类栖息带,流场效应较好;礁群的实施对海床泥沙活动影响相对较小,短期内人工鱼礁下沉或掩埋的风险较小。
With the decline of marine fishery resources and deterioration of marine environment,artificial reef technology has been developed rapidly and become an important part of the marine ranching construction.In this paper,a current mathematical model of artificial reefs for Lusi Fishing Ground was established by CJK3D-WEM,which aimed to simulate the changes of hydrodynamics in the surrounding waters after the implementation of the reef group and analyze the stability of the artificial reef group considering the reactivity of seabed sediment.The analysis results show that the barrier effect of the reef can form a fusiform mild flow behind the reef,and the nearer to the reefs is,the slower the flow is.A biological and fish habitat with gradual changing flow is formed among the reefs,and the flow field effect is satisfied.The implementation of the reefs has less effect on the sediment activity of the seabed,and the sinking or buried risk of the artificial reefs is less in a short term.
