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。
According to the survey results of 9 voyages from November 1993 to October 1994, the distribution and characteristics of POC in the culture area of Sanggou Bay were discussed. The results showed that there was a significant plane distribution and seasonal variation of POC in the bay under the influence of mariculture and wind agitation. However, there is no significant difference in the vertical distribution of POC. The POC of the bay has a positive correlation with Chla. In line with the estimation results of other waters, the higher POC and POCB values appear in the season conducive to phytoplankton growth, Conversely, when the growth of phytoplankton is limited due to temperature decrease or lack of nutrients, the ratio is minimized. The POC value of true ocular layer under the water column of the bay was 29 days.
