Bifurcation in a Predator-prey Model with Time Delay and Stocking Rate

摘要：

A predator-prey population model with delay and stocking rate is investigated in this paper. Stability and bifurcation of the population is considered. Suf.cient conditions for stability and bifurcation is obtained by studying the characteristic equation; With numerical simulation method about the population model, the trace of the phase plane is found. By studying time delay and stocking rate in.uence on the stability of the population, the theoretical analysis results are proved to be correct.
