厦门西港和九龙江口颗粒有机碳的研究

Abstract

研究了九龙江河口及相邻海区颗粒有机碳 ( POC)的分布变化特征及 POC与浮游植物生物量的关系。结果表明 ,九龙江河口区和厦门西港 POC的平均含量分别为 762和 793μg C/l。春季 ,河口区的 POC含量高于西港 ,而秋季则相反。春季 ,河口区和西港的 POC含量与ATP(三磷酸腺苷 )含量都呈正相关关系 ,其中 ,浮游植物有机碳 ( POCb)分别占 POC的 4 4 %和 2 2 %。

The characteristics of the distribution of particulate organic carbon (POC) and its relationship with phytoplankton biomass are studied.The results show that the average contents of POC in the Xiamen Western Harbour and in the Jiulong jiang River estuary are 762 and 793 μgC/L respectively.The contents of POC in the estuary were higher than those in the Xiamen Western Harbour in spring, but lower in autumn.POC contents were positively correlated to ATP (adenosine triphosphate) both in the estuary and the Xiamen Western Harbour in spring, in which Organic carbon of phytoplankton (POC B) were 44 % and 22 % in POC respectively.
