摘　　要：在一个简单渔业生物经济模型的基础上,研究了该模型在有效平衡点附近位置的局部稳定性。模型中考虑了资源生长和捕捞努力量随时间、资源量、价格等因素的变化,通过该非线性模型在平衡点附近的扰动方程,对其局部稳定性进行了分析,并给出了数值分析的结果。研究表明,模型在平衡点附近的局域是稳定的。该项工作对于分析渔业生物经济系统的特征,揭示模型中各因素之间的相互关系和指导渔业政策的制定等,有一定的借鉴意义。Based on the simple bioeconomic model of fisheries, the local stability of this model at the equilibrium point was studied. In this model, the changes of resource development and effort with time, volume of resource, price and so on were considered. According to the perturbation equation of this nonlinear dynamic model near the equilibrium point, analysis of its local stability was achieved and the numerical value analysis was also given in this paper. Our research suggested that the model was stable in the local area near the equilibrium point. This work is useful for analyzing the characteristics of fisheries bioeconomic system, uncovering the relationships between all kinds of factors and making the policy of fisheries.
