摘　　要：模型表明:潮流和波浪混合对南黄海水动力及生态特征的形成起着不可忽视的作用,二者分别破坏上、下层水体的稳定,使上混合层和次表层加深,并促进水体内部的水交换;中部海域春季表层的浮游植物浓度最高,夏天次表层浓度则最高,秋季发生一次弱势水华;近岸海域夏天浓度高但不出现次表层最大化;近岸水域浮游植物生长主要受光照限制,而中部海域受温度、光照和营养盐的限制,且在不同时间和水层的影响程度不同;营养盐方面,P是限制浮游植物生长的主要因子。The model showed that the tidal process and wave-mixings played important roles in forming physical and ecological patterns of South Yellow Sea.They blent top and bottom layers,accelerated the formulation of thermocline,and promoted abilities of water exchange.The wave mixings deepened the top mixed layer and the subsurface layer.In the central area,the top layer had the highest density of phytoplankton in spring,which was a critical bloom in a whole year.From late spring to late summer,the maximal density was presented in subsurface layers.A weak bloom happened in the central area in fall.In coastal areas,summer had the highest phytoplankton density and did not appear a phenomenon of maximization in subsurface layer.The growth of phytoplankton was limited by the light in the coastal areas,but by temperature,light and nutrients in the central areas,where three factors played different roles in different time and layers.Among nutrients,phosphorus was a key factor of the limiting growth.
