摘要 研究了非自治两种群浮游生物相克模型.通过构造适当的绝灭函数,得到了保证系统中某个种群绝灭和另外一个种群全局吸引的充分性条件.所得的结果补充了前人的工作. The non-autonomous two species allelopathic phytoplankton model is studied. By constructing some suitable Lyapunov type extinction functions, sufficient conditions which guarantee the extinction of species and the global attractivity of another species are obtained. The results supplement some known results.
