在对长乐漳港海域水动力模拟研究的基础上,采用质点跟踪的方法,模拟外文武海湾围垦前后海蚌浮游幼体的漂移路径,并由此评价海湾围垦对海蚌苗种资源分布的影响,为海蚌苗种资源保护提供科学依据。模拟结果显示,围垦前,海蚌浮游幼体经过10 d的漂浮与迁移将附着于海湾口门附近海域,分布范围较大;围垦后,海蚌浮游幼体最后的附着区域将在垦区外侧,分布范围较小;外文武海湾围垦很大程度上改变了海蚌浮游幼体在变态为稚贝之前的浮游路径,使之不能在丰富饵料的海湾口附近附着。这说明了外文武海湾围垦是导致垦区外侧海蚌分布格局变化的影响因素之一。
Based on the study of hydrodynamics in the Changle Zhanggang sea area, the particle tracking method was used to simulate the drift path of the mussel larvae before and after reclamation in foreign-wuhai Bay, and to evaluate the effect of reclamation on the resource distribution of mussel in the Gulf. Provide scientific basis for the protection of sea mussel resources. The simulation results showed that the floating and migrating of mussels in the sea mussel would adhere to the sea near the mouth of the bay for a long time before reclamation and the distribution range was larger. After the reclamation, the final attachment area of the mussel larvae would be outside the reclamation area, Smaller; foreign Wu Bay reclamation to a large extent changed the mussels mustelimdal plankton metamorphosis juvenile before the planktonic path so that it can not be rich in food near the mouth of the bay. This shows that the foreign Wuhai Bay reclamation is leading to the reclamation area outside the distribution pattern of the mussels one of the factors.
