摘要
研究了一类具有Holling Ⅳ类功能反应的变系数多种群捕食者-食饵系统的持久性生存.利用比较定理,得到种群一致持久生存的充分条件.该结果改进了已有结论.
The persistence of variable coefficient muhispeeies predator-prey systems with Holling IV type functional response was discussed in this paper. Making use of comparison theorem, the sufficient conditions of the uniform persistence of populations were obtained. Our results improved the existed results.
