摘  要：
以东吾洋内湾海域环境为研究对象,基于验证的MIKE21中的HD和MT模型,计算分析了单一建设仙东渔港工程、单一建设关门渔港工程和两个渔港工程同时存在三种情景下东吾洋海域潮流场和泥沙场的变化。结果表明,当单一建设关门渔港工程时,流速增幅区域面积最大,关门水道附近泥沙强冲刷区域面积最大;当关门和仙东渔港工程同时存在时,流速增幅及泥沙强冲刷区域面积次之;而当单一建设仙东渔港工程时,流速增幅及泥沙强冲刷区面积最小。相较于其他两种情景,当单一建设关门渔港工程时,关门水道附近水动力条件最强,高流速水体导致沉积在底部的泥沙产生紊动使得水质变得浑浊,对周围藻类植物及浮游动物的生长产生极大的负面作用,也会大大降低紫菜海带养殖区及网箱养殖区的产量,另外对大黄鱼产卵区的分布也会造成很大的冲击。综合考虑,仙东渔港建设较为合理,而关门渔港的选址存在问题。

摘  要：
HD and MT models in MIKE21 verification were used to studying the environmental impact of fishing engineering to Dongwuyang Internal Bay.The change of Dongwuyang tidal current field and sediment field in presence of Xiandong and Guanmen fishing port projects were calculated and analyzed,individually and simultaneously.The results showed that in the existence of Guanmen fishing port project,the area of the sediment erosion near Guanmen water course was the largest.In the existence of Guanmen and Xiandong fishing port projects,the growth of water flow velocity and area of the strong sediment erosion was smaller.However in the existence of Xiandong fishing port,the growth of water flow velocity and area of the strong sediment erosion were the smallest.The Guanmen fishing port made the hydrology in Guanmen waterways and area of north extender to be the biggest.This scenario resulted in turbid water and had the greatest impact on the growth of surrounding algae and zooplankton.It also reduced the yields of farmed laver and kelp and cultured animals.Besides,such scenarion caused a great influence on the distribution of spawning area of large yellow croaker.Taking togather,Xiandong fishing port construction was reasonable,but the location of Guanmen fishing port remained some problems.
