关于Holling Ⅱ类功能反应和周期系数的n维食物链系统的研究

STUDY ON THE SYSTEM OF n SPECIES FOOD CHAIN WITH HOLLING'S TYPE Ⅱ FUNCTIONAL RESPONSE AND PERIODIC COEFFICIENTS

研究了一类具有密度制约、周期系数和被食者对捕食者均有ＨｏｉｌｉｎｇⅡ类功能反应的ｎ维食物链系统的稳定性，得出了该系统存在唯一、全局渐近稳定周期解的充分条件．

A system of n species food chain with peridic coefficients and Holling's type Ⅱ functional response and conditioned density was discused.Sufficient conditions of the globally asymptotic stability and uniqueness of periodic solution were obtained.
