In this thesis, using the qualitative theory and stability theory of ordinary differential equation, we study the global stability of equilibrium, existence and uniqueness of limit cycle for a predator-prey model with sublinear functional response function.

本学位论文利用常微分方程定性理论和李亚普诺夫稳定性理论的基本方法，研究了具次线性功能性反应函数的食饵-捕食者模型的平衡点的全局稳定性，极限环的存在性和惟一性。

The purpose of chapter 4 is to study a predator-prey model with sublinear functional response function and sublinear density control function. Some results dealing with stability of equilibrium, nonexistence , existence as well as uniqueness of the limit cycle around the positive equilibrium of the model are obtained.

第4章分析了一类食饵的相对增长率和功能反应函数均为次线性函数的食饵-捕食者模型，通过分析，得到了该系统的正平衡点全局稳定和存在惟一极限环的充分条件。

In the last chapter, we consider a predator-prey model with sublinear functional response function, sublinear density control function and constant stocking rate. The properties of equilibrium, existence and uniqueness of the limit cycle around the positive equilibrium investigated.

第5章讨论一类食饵具常数存放率的功能性反应模型，研究了模型的平衡点的性态，系统的全局稳定性，极限环的存在性和唯一性，获得了一系列较为完整的结论。

The theoretical analysis are verified by numerical simulations.Chapter 3 mainly considers a class of predator-prey model with sublinear functional response function. We deduce some sufficient conditions ensuring stability of equilibrium, nonexistence , existence as well as uniqueness of the limit cycle around the positive equilibrium.

第3章研究了一类食饵为线性密度制约，功能反应函数为次线性函数的食饵-捕食者模型，完整地对模型的平衡点的全局稳定性和极限环的存在惟一性进行了定性分析，得到了该系统不存在闭轨线，正平衡点全局稳定和存在惟一稳定的极限环的充分条件。
