摘要(Abstract)：

本文基于南海SEATS站的观测资料,利用垂直一维海洋生态系统动力学模式(MEM-1D)模拟了南海北部生态要素垂直结构的季节变化。结果表明,南海北部表层Chla浓度具有明显的季节变化特征,夏季呈现低值(<0.05 mg·m-3),冬季呈现高值,12月为0.38 mg·m-3。春季,风速相对变小,垂直混合变弱,次表层Chla浓度极大值现象形成(80~100 m),并可一直持续到10月末。冬季,海表温度降低,东北季风爆发,垂直混合增强,出现表层水华现象。浮游动物和细菌的垂直结构相似,冬季上层水体中浮游动物和细菌出现最大值,分别为13 mg·m-3和18 mg·m-3。3~10月细菌(12 mg·m-3)同浮游动物(14 mg·m-3)一样出现次表层最大值,其存在深度与浮游动物相似。
