CONDITIONS FOR GLOBAL ATTRACTIVITY OF RATIO-DEPENDENT MULTISPECIES ECOLOGICAL COMPETITION-PREDATOR SYSTEM WITH HOLLING Ⅲ TYPE FUNCTIONAL RESPONSE

摘要

＜正＞In this paper, a nonautonomous ratio-dependent multispecies competition-predator system with Hoiling’s Ⅲtype functional response is studied, where all parameters are time dependent. It is proved that the system is uniformly persistent under suitable condition. Furthermore, the sufficient conditions are established for global attractivity of a periodic solution of the system.
