摘　　要：基于无结构网格和有限体积法的海洋模型FVCOM(Finite Volume Coastal Ocean Model),并结合2个连续测流站、2个水位站的观测资料,选取对养殖潜力影响最大的颗粒有机碳(POC)和溶解有机碳(DOC)作为本研究海区营养物质的表征变量,依据不同季节和影响因子共设计了18种计算方案,对长海县附近海域营养物质的交换能力分别进行了诊断和计算,对各个影响因子在营养物质交换过程中的重要性进行了初步评估。研究得出,北黄海环流对该海域物质交换能力的促进作用强于风生流的作用。By making use of FVCOM（An Unstructured Grid,Finite-Volume Coastal Ocean Model）and being based on the consecutively observed data from four hydrometric stations,three waterlevel instruments and one ADCP in this sea area,choosing POC and DOC which have the most significant impact on the potential of mariculture as study variables to represent the seeds of nutrients,we calculated and diagnostically analyzed the exchange capacity of nutrients County Chinghai in eighteen conditions based on the proportions of different factors and seasons.The importance assessment of each factor during the nutrients exchange is provided.This study indicated that the material exchange in North Yellow Sea was strongly influenced by baroclinic flow and wind-driven current,and the former had more effect.
