摘要
应用氚化胸苷示踪法研究了滆湖浮游物与沉降物中细菌生长速率的动态变化，同时测定了滆湖有机碎屑沉降量、水体中有机物含量以及C／N的动态变化。结果表明：滆潮浮游物与沉降物中细菌生长速率的变化具有很明显的季节性，其与水温、水环境中的有机物含量、碳氮比、有机碎屑沉降量等存在密切的联系。我们认为，细菌生长速率是阐明湖泊生态系结构与功能的主要参数，也是水体渔业开发的重要依据之一。
Seasonal variation of bacterioplankton growth rate was measured with 3H- thymidine tracing method in Gehu Lake, along with the measurement of sedimentation of detritus, content of organic matter and C/N ratio of particulate and sedimented matter. The results show that there exist marked seasonal variations in growth rate of bacteria on season,sedimented matter, and is highly related to water temperature, organic matter concentration, C/N ratio and sedimentation of organic matter. The bacteria growth rate is an important parameter of structure and function of lake ecosystem, and also constitute the base for fisheries exploitation.
