养殖浮筏对海州湾水交换能力影响的研究
Study on the effect of culturing floating raft on water exchange capacity in Haizhou Bay
摘要
Abstract
Haizhou Bay is the largest raft culturing base of laver in China.A numerical simulation is conducted to study the effect of culturing floating rafts on the hydrodynamic conditions and water exchanged capacity of Haizhou Bay.A hydrodynamic model of Haizhou Bay is developed using the Finite Volume Coastal Ocean Model(FVCOM)and a dual-drag model considering the influ-ence of floating rafts is introduced to the hydrodynamic model.The hydrodynamic field,tide volume,and water exchange capaci-ty of Haizhou Bay area are simulated.The results show that,in the bay,floating rafts severely attenuate the hydrodynamic field,reduce the surface velocity in the cultured area by 10％-50％,and decrease the tide volume,with a maximum decrease of 0.21×108 m3.Furthermore,the semi-exchange period of seawater is extended by 16 tidal periods,and the average semi-ex-change time is extended by 20％,demonstrating that the existence of culturing floating rafts in the bay weakens its water exchange capacity.Finally,through numerical experiments,the contribution of setting up waterways in the cultured floating raft area to im-prove the water exchange capacity of the bay is discussed.关键词
