摘要 研究一类带有反应扩散项的两种群Gilpin-Ayala竞争系统.利用单调半流双稳定性理论,得到该竞争系统存在双稳定性的全局动力学行为.即在一定条件下,系统存在一条无序的、不变的一阶光滑分界线,使得当初值在分界线上方,种群2赢得竞争;而当初值在分界线下方,则种群1赢得竞争. We study the bi-stability of a Gilpin-Ayala competition model with reaction diffusion.By virtue of the theory of saddle-point for monotone semiflows,we prove that the system admits a K-unordered,invariant C^1 separatrix in which species 2 wins whenever the initial value is above the separatrix,while species 1 wins whenever the initial value is below the separatrix.
