| 摘 要： | 对５个对虾养殖围隔生态系浮游细菌的数量动态进行了研究。结果表明：浮游细菌数量波动在（０．４１～１０．６３）×１０６ｍｌ－１之间，平均为（４．２９±２．４４）×１０６ｍｌ－１。随着养殖时间的推移，细菌数量逐渐上升，细菌数量昼夜间呈现较大波动。细菌数量与水温、总有机质的化学需氧量（ＴＣＯＤ）、溶解态有机质的化学需氧量（ＤＣＯＤ）呈现显著正相关，与颗粒态有机质的化学需氧量（ＰＣＯＤ）、浮游动、植物生物量无显著相关性。

| Abstract: | Numerical dynamics of bacterioplankton in 5 shrimp cultural enclosure ecosystems were studied.The results were that the number of bacterioplankton fluctuated between 0.41106 ml-1 and 10.63106 ml-1 with an average of (4.292.44)106 ml-1, and increased gradually with the lapse of cultural time.Bacterioplankton exhibited an obvious diurnal numerical fluctuation. Bacterioplankton numbers were correlated positively with water temperature,total chemical oxygen demand (TCOD) and dissolved oxygen demand (DCOD), but was not correlated significantly with particulate oxygen demand(PCOD), zooplankton and phytoplankton biomasses. |
