| 摘 要： | 以Lotk-volterra 的双种竞争模型为基础,进行实验设计研究隆线溞对微囊藻和栅藻竞争的影响.结果显示,含有隆线溞的微囊藻和栅藻共培养组中微囊藻的增长率(r=0.446±0.049)大于微囊藻和栅藻共培养组中的增长率(r=0.394±0.062).经拟合计算得到微囊藻对栅藻的竞争抑制参数(α)为0.81±0.11,栅藻对微囊藻的竞争抑制参数(β)是0.23±0.08,α是β的3.5倍;含有隆线溞组中微囊藻对栅藻的竞争抑制参数(α')为1.04±0.24.栅藻对微囊藻的竞争抑制参数(β')为0.19±0.02,α'是β'的5.5倍,显然由于隆线溞的存在增强了微囊藻对栅藻的抑制能力. |
