摘要
Abstract
A class of Lotka-Volterra model of diffuse predat or-prey is analysed,which has the following features:if there is a positive bal ance point in this system,all its positive balance points are bounded and st rongly persistence;if the model has a small diffuse rate,its positive balance po int will fluctuate steadily,but when the diffuse rate increases to a certain deg ree and keeps changing in a certain open interval,the positive balance point will fluctuate unsteadily and branch out one periodic solution within a sm all amplitude;if the diffuse rate keeps increasing and goes beyond the certain d egree,the positive balance point will fluctuate in a steady rate again.关键词
