摘要
1997年 6～ 8月于山东省海阳市黄海集团公司养虾场 ,采用围隔实验生态学方法研究了虾池生态系各有机碳库的储量 ,结果表明 :溶解有机碳 ( DOC)、颗粒有机碳 ( POC)库储量 ( mg C/l)平均分别为 9.95± 2 .0 4及 3.1 0± 1 .60 ,DOC/POC比值平均为 3.2 1。POC库中 ,腐质颗粒碳为总浮游生物碳的 2倍。浮游植物碳、浮游动物碳、浮游细菌碳平均分别占总浮游生物碳的 53%、1 3%及 34 %。腐质碳、总浮游生物碳平均分别占总有机碳 ( TOC)的 92 %及 8% ,腐质碳为总浮游生物碳的 1 1 .0 8倍。
Storage of the organic carbon pools in the ecosystems of shrimp ponds was studied with experimental enclosures.The results show that the storage of dissolved organic carbon(DOC)and particulate organic carbon(POC)pools(mgC/l)were 9.95±2.04 and 3.10±1.60,respectively.The average ratio of DOC/POC was 3.21.The storage of particle detritus carbon was 2 times higher than that of total planktonic carbon.Organic carbon storage of phytoplankton,zooplankton and bacterioplankton were 53,13 and 34 percent of the total plankton carbon,respectively.Detritus,total plankton carbon storage was 92 and 8 percent of TOC,and detritus carbon was 11.08 times as that of total plankton carbon.
