通过测定铜绿微囊藻、菌、病毒的数量以及总磷、总氮的浓度变化,研究了富营养化水体中藻、菌、病毒之间的数量关系.结果表明:病毒和第二天的藻细胞数呈显著负相关(r=-0.655,P<0.01),其显著水平高于与当天藻细胞数的相关性(r=-0.578,p<0.05),菌和第二天的藻也具有显著负相关性(r=-0.500,P<0.05),回归分析表明,病毒的波动能够解释51.9%的藻细胞数的变化,菌的波动能够解释46.4%的藻细胞数的变化,藻细胞数与菌数的回归方程的确定系数低于藻细胞数与病毒数的确定系数.此外,藻和总磷存在极显著负相关性(r=-0.747,P<0.01),病毒和总磷之间存在极显著正相关(r=-0.857,P<0.01).上述结果说明,浮游病毒和浮游细菌丰度是影响藻类数量的重要因子,且富营养化水体中的浮游病毒可以通过裂解宿主细胞而加速了磷元素的循环.

By measuring the abundance of Microcystis aeruginosa, bacterioplankton, virioplankton and the concentration of total phosphorus and nitrogen in eutrophication water bodies, the quantitative relationship among M. aeruginosa, bacteria and viruses was studied. Results indicated that the viral abundance had marked relation with the density of M. aeruginosa in the next day, with marked level higher than the relativity in the same day. Number of bacteria was closely correlated to algae in the next day. Regression analysis suggested that the fluctuation of virus could explain 51.9% of fluctuation of M. aeruginosa and the fluctuation of bacteria could explain 46.4% of fluctuation of M. aeruginosa. Coefficient of determination of regression equation of M. aeruginosa and bacteria was lower than that of M. aeruginosa and virus. Total phosphorus was negatively correlated to the number of algae and positively correlated to the number of viral abundance. Results implied that both virioplankton and bacterioplankton abundance may contribute to the control of M. aeruginosa density. It also demonstrated that virioplankton may accelerate the flow of phosphorus by lysing host cells in eutrophication water bodies.
