摘　　要： 通过对眼点拟微绿球藻和扁藻进行共培养试验,结果表明,在共培养条件下,眼点拟微绿球藻和扁藻的生长速度均受到抑制,即两种藻的最大生长密度均比对照(分别单独培养)有显著降低,而且眼点拟微绿球藻降低的程度要大于扁藻。经计算两种藻的种间竞争系数可知,扁藻的种间竞争能力明显强于眼点拟微绿球藻。 Experiments of co-culture with Nannochloropsis oculata and Platymonas sp. were carried out, and the results showed a transparent phenomenon of interspecific bating between them under the condition of co-culture. In the co-culture, maximum densities of the two specieses were affected, with a greater influence on Nannochloropsis oculata than on Platymonas sp. through comparing with those from the pure culture of the two species. Each of the interspecific competitive parameters of one species to the other was calculated, the results showed Platymonas sp. possessed a more interspecific competitive capacity.
