摘　　要：研究了一类具有竞争关系的密度制约的两种群模型,运用传统的微分方程稳定性理论,分析模型平衡点的性态,得到了唯一正平衡点的全局稳定性的条件,从而得到自然环境中两种群之间的微妙关系.A competitive relationship model of density restriction between two species was studied using traditional differential equation stability theory. The normal balance point of the model was analyzed, get the global stability condition with a unique positive equilibrium point was obtained. Thus, the delicate relationship between the two species under natural environment was obtained.

关 键 词：竞争 密度制约 平衡点 稳定性
