摘要
对种群服从Gompertz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,并对其进行了详细分析.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做出了解释.探讨了关于生物资源开发的相关问题,为生物资源的实际开发与管理提供了必要的理论依据.
Based on the Gompertz equation,a mathematical bioeconomic model is established where the price varies with the change of demand ans supply.Detailed qualitative analyses of the model are carried out including the existence and stability of equilibria and the nonexistence of limit cycle.Biological and economical significance of the main results are presented also,which provides theoretical bases for the optimal harvesting and management of renewable biological resources.
