梅东浅滩围垦对水流影响的数值模拟

由于梅山本岛土地资源紧张，为了实现梅山规划区块功能，初步考虑在梅山本岛东部围垦以建设梅山通用航空产业基地等基础设施。采用MIKE 21 HD水动力模型对梅山水道封堵前提下5个不同围垦方案实施后对梅山岛海域的流场情况进行了数值模拟，并对比围垦实施前后潮流场变化情况，对各方案进行初步比选。从模拟结果可以看出，规划梅东围垦工程的建设不会改变大范围整体海域的流场结构。总体而言，梅东围垦方案一围垦范围最小，受其影响的范围也相对较小，而方案5由于未封堵扑蛇山与梅山间汊道，因此其对穿山南作业区的影响程度要小于其他各封堵汊道的方案。

Numerical modeling of influence on current due to reclamation in Meishan

Due to the absence of the ground resource, the construction land of the general aerial industry baseis planned to get from reclamation in the east of Meishan to construct infrastructures in order to satisfy the functionsplanning of Meishan. We use the MIKE 21 HD model to simulate the influence on current due to the planned fivedifferent reclamation scenarios in the east of Meishan after plugging the Meishan waterway, and make a comparisonaccording to the modeling results. The modeling results reveal that the influence of the planned reclamationproject to the larger area tide field is little. Generally speaking, the influence of the first scenario is the least as itsreclamation area is the least among the five scenarios. While the fifth scenario has the least influence on the southChuanshan operation area, as the waterway between Pusheshan mountain and Meishan is not plugged.
