摘要(Abstract)：

海州湾是我国最大的紫菜筏式养殖基地。采用数值模拟方法研究了养殖浮筏对海州湾水动力条件和水交换能力的影响。首先,利用基于有限体积的海洋数值模式(FVCOM)建立了海州湾水动力模型,并在模型中引入考虑浮筏影响的双阻力模型,对海州湾海域的水动力场、纳潮量和水交换能力进行了模拟。结果表明,养殖浮筏严重削弱了海湾内水动力场,使养殖区域的海表流速降低10%～50%;纳潮量减少,最大减少了0.21×10~8 m~3;海水半交换周期延长了16个潮周期,平均半交换时间延长了20%,表明海湾内养殖浮筏的存在降低了水交换能力。最后,通过数值实验,探讨了在养殖浮筏区设置水流通道对提高海湾水交换能力的贡献。
