摘要
对种群服从Ricker增长的开放式生物资源建立了价格随供求而变化的捕获模型,并进行了详细分析论证。利用常微分方程中的定性理论和稳定性理论,讨论了平衡点的存在性、稳定性及极限环的不存在性。从生态学和经济学的角度对所得到的结果作出了解释,探讨了关于生物资源开发的相关问题,为生物资源的开发与管理实践提供了理论依据和对策建议。
A preying model in which the price changes according to supply is built on the biological population in compliance with Ricker＇s growth of the open biological resources and supported by detailed analysis and proving. Based on the qualitative theory and theory of stability of ordinary differential equation, this paper discusses the existence, stability of equilibrium point and the non-existence of limit cycle. Additionally, the result is explained from the view of biology and economics. Relevant questions on biological resources are also discussed in this paper. It provides a theory and strategy for the development and management of the biological resources.
