摘要
根据 1993年 11月至 1994年 10月间 9个航次的调查结果 ,讨论了桑沟湾养殖海域POC的分布与特征。结果表明 ,受海水养殖生产及风搅动等因素的影响 ,该湾的POC有显著的平面分布和季节变化。但其POC的垂直分布无显著性差异 ;该湾的POC与Chl a之间呈正相关关系 ;与其它海域的估算结果相符 ,POC与POCB比值的较高值出现在有利于浮游植物生长的季节 ,反之 ,因温度降低或营养物质缺乏使浮游植物生长受限时 ,该比值降至最低点。该湾单位水柱下真光层中POC的τ值为 2 9d。
Distribution and features of POC in cultivating waters of Sanggou bay was discussed, according to the nine investigations from Nov. 1993 to Oct. 1994. Horizontal distribution or season change of POC was remarkable, but vertical distribution change was not apparent. There was a positive linear interrelation between POC and Chl a. It was agreeable to the research results of other seawaters that larger POC B/POC value always appeared when photoplankton rate growing faster. The retention period of POC in euphonic zone was estimated to 29 days.
