具时滞和营养循环的种群竞争模型

MODELS OF COMPETITION WITH RETARDED DELAY AND NUTRIENT RECYCLING

本文讨论了两种群竞争某一有限营养的模型 ,针对时滞和营养循环的作用 ,利用Hopf分支及Rabinowitg分支理论证明了两种群共存的可能性。

Models of competition of two populatons are discussed. By using bifurcation theory, the possibility of the co_existence of the two populations is proved in accordance with retarded delay and nutrient recycling.
