摘　　要：本文以莱州湾海洋环境为研究对象,采用数值模拟,分别从海域空间、水动力和生态环境3个方面,分析了2000—2005年、2005—2010年和2010—2013年莱州湾3个阶段围填海工程对其海洋环境产生的累积影响。结果表明,2000—2013年围填海工程导致莱州湾的海域面积减小了约6.3%,岸线长度增加了18.1%;影响流速等级为Ⅲ级的海域面积累积约1 069km^2,大、小纳潮量分别减少了3.81%和4.76%;围填海工程还导致莱州湾的生物资源多样性程度和数量下降。十几年来的围填海对莱州湾海洋环境的累积影响较大。This paper takes marine environment in Laizhou Bay as the research object.The cumulative effect of coastal reclamation on the marine enviroment has been analyzed from maritime space,hydrodynamic and ecological environment cumulative changes for three stages of 2000-2005,2005-2010 and 2010-2013 through numerical simulation method.The results show that the sea area has been reduced about 6.3%,and shoreline length has been increased 18.1%.The affecting velocity level for III of the sea area has been accumulated about 1 069 km 2,and large and small tidal volume has been reduced 3.81%and 4.76%.The reclamation also leads to a decline in biological resources of diversity and quantity in Laizhou Bay.The large scale of the reclamation in the Laizhou Bay has a greate impact on the marine environment.
