| 摘 要： | 目的]研究不同营养条件下铜绿微囊藻和衣藻间的种群竞争关系。方法]以Lotka-Volterra的双种竞争模型为基础,通过纯培养取得参数K和r,变模型的微分形式为差分形式,以生长拐点出现时间作为竞争参数的起始时间,经模拟计算获得2种藻间的竞争参数。结果]在中、富、重富营养条件下,铜绿微囊藻竞争抑制能力要高于衣藻,而在基础培养条件（M-11培养液）中2种藻的竞争抑制能力相近。结论]该研究为防控水华的暴发提供理论基础。

| Abstract: | Objective]The research aimed to study the species competition between Microstic aerugunosa and Chlamydomonas sp.under different nutritional conditions.Method] Based on the two-species competition model of Lotka-Volterra,the parameters of K and r were obtained by pure culture,the differential form of the model was changed into differences forms and got the time of growth inflextion as the start-time of competitive parameters which obtained through simulating calculation.Result]The ability of competitive i... |
