| 摘 要： | 通过对水体中及附着在藻类上的细荫数量、代谢活性细菌、Chl.a浓度等的研究,探讨了藻类与细菌之间的代谢耦联关系,结果表明:1)水体中细菌的丰度随着Chl.a浓度的增加而逐渐增大(r2=0.466,P<0.05),但其峰值滞后于Chl.a;附在藻体表面上的细菌也呈现出相似的变化规律;2)水体中代谢活性细菌数量与总细菌数量显著相关(r2=0.678,P<0.05);附着在藻体上的代谢活性细菌虽然总数量低于水体中的代谢活性细菌,但二者之间亦存在显著的相关性(r2=0.836,P<0.05).3)藻类表面附着细菌的数量取决与藻类的生长状况,附着在藻类体上的代谢活性细菌的比率均高于水体中代谢活性细菌的比率,且在水华盛行期间呈逐渐增加的趋势. |

| Abstract: | The bacterial abundance and active bacterial abundance of water and algae attached, as well as the Chl.a and nutrient concentrations, were investigated, and the metabolism coupling between algae and bacteria were also discussed. The results showed: 1) The bacterial abundances of water increased with the Chl.a concentrations increasing(r2=0.466, P<0.05), although the peak value was delayed with the Chl.a concentration. Variation of the algae attached bacterial abundances were the similar patterns. 2) There w... |
