摘  要：
丁字湾的规划会对丁字湾内水动力和纳潮量有影响,从而影响着丁字湾与外海的水交换,影响丁字湾内水质与生态环境。本文利用二维潮波运动方程建立了崂山头至古龙咀以西海域潮流数值计算模式,数值模拟了规划实施前后丁字湾内水动力和纳潮量的变化,数值模拟结果表明:丁字湾规划实施后,整个规划范围内大部分区域流速增大,尤其丁字湾中央水道流速增大明显,涨潮时,丁字湾湾口附近水道流速增量最大,在0.48m/s以上,落潮时马河港大桥处的流速增量最大,在0.54m/s以上。湾外流速变化不大。丁字湾内纳潮量增大了42%(海即大桥连线)、33%(丁字嘴—栲栳岛连线),丁字湾规划大大改善了丁字湾的水动力,增加了丁字湾内纳潮量。规划有利于丁字湾与外海的水交换和湾内水质与生态环境的改善。

摘  要：
The planning of Dingzi Bay will impact its hydrodynamic and tidal water capacity,thus affecting the water exchange as well as the water quality and ecological environment in Dingzi Bay.In this paper,the tidal current numerical model is developed by two-dimensional tidal motion equation in the west area of Laoshantou to Gulongzui.And the hydrodynamic and tidal water capacity changes are simulated before and after the planning implementation. The simulation results show that the current velocity in most planning regions will increase after the planning implementation,especially in the middle waterway of Dingzi Bay.During flood tide period,the increment of current velocity near the mouth of waterways is the most with more than 0.48m/s,while the maximum increment of ebb tide occurs near Mahe Port Bridge in 0.54m/s or more.However,the velocity changes little in the area outside the Bay. With respect to tidal prism,it will increase by 42% in the connection line of the Hai-Ji sea-crossing bridge and by 33% in the line connecting the Dingzizui and Kaolao island. All the analysis shows that the planning of Dingzi Bay will greatly improve its water dynamic,and increase its tidal water capacity.Therefore the planning is in favor of water exchange of Dingzi Bay and the open sea.the water quality ecological environment in Dingzi Bay will also be improved as well.
