围填海工程对莱州湾水动力条件的影响

The Hydrodynamic Response to Reclamation in Laizhou Bay

本文采用数值模拟的方法研究了2003—2013年10年来围填海工程建设对莱州湾水动力环境的影响。结果表明2003—2013年围填海工程的建设导致了莱州湾海域面积减小7.38%;围填海工程使莱州湾流速整体呈减小趋势,流速减小超过4cm/s面积约占整个海湾面积的24.3%,流速增加大于4cm/s区域仅占4.0%,流向变化整体较小;莱州湾的纳潮量明显减小,平均纳潮量减小了5.57%;围填海工程建设使莱州湾水交换率略有减小。围填海工程弱化了莱州湾的海湾属性。

The authors studies the hydrodynamic environment influence of reclamation project form 2003 to 2013by the numerical simulation method.The results show that the reclamation led to the water area of Laizhou bay decreased by 7.38%from 2003 to 2013.The Laizhou Bay reclamation project led to flow velocity inteqral decrease.The flow velocity was reduced more than 4cm/s aera accounted for the entire bay area 24.3%.The flow velocity was increased more than 4cm/s aera accounted for only 4%.Flow direction changed the overall smaller.Th storage capacity of tidal water obviously reduced in laizhou bay.The average tidal volume decreased by 5.57%.The redamaxion project led to decrease slightly of water exchange rate.The reclamation project weaken gulf attribute of laizhou bay.
