提出和分析了一类带有阶段结构的渔业收获模型,讨论了该模型的平衡点的存在性和局部稳定、不稳定性以及全局稳定性,得到了保持渔业的持续生存、稳定和税收闽值.
A stage-structared fishery model with harvesting is proposed and analyzed in this paper. The existence of the equlibria of the model, along with their local stability, instability and global stability are discussed, respectively. Taxation threshod is obtained to sustain permanence and stability of the fishery resources.
