【摘要】 基于罗源湾2013年4至5月潮位、潮流实测数据,结合数值模拟,对比分析历史资料和模拟结果,研究了大规模高密度养殖区内潮动力结构的特征及其对养殖活动的响应。潮流在罗源湾养殖区,基本呈两层结构,近表层以落潮流为主,中底层以涨潮流为主,潮流主要从中下层流入,表层流出。高密度的养殖设施和生物的存在,阻碍了海湾水体的流动,致使水平流速垂向上出现"双边界层"结构,表层和底层的流速较小,最大值出现在中下部,平均流速整体减小,潮汐不对称效应减弱,潮波变形程度降低。
【Abstract】 Based on the measured data of tidal level and tidal flow in Luoyuan Bay from April to May in2013,by comparison analysis of historical data and the numerical simulation results,tidal dynamic structure characteristics on large- scale high density aquaculture area and its response on aquaculture activities were studied in the paper.Tidal flow has two- layer structure from ebb- dominating near the surface to flood-dominating in the middle and bottom layers,and it flows in from the middle and bottom layers and flows out from the surface.The existence of high density aquaculture facilities and biology has hindered the gulf water flowing,resulting in horizontal flow speed having double boundary layer structure vertically,that is,the velocity in the surface and bottom layers is small while maximum value appears in the middle and lower part of the water,the average flow speed decreases overall,the nonlinear effect weakens,the degree of tidal wave deformation decreases.
