动态价格下Logistic生长模型的捕获问题

Harvesting in Logistic System with Dynamic Price

基于市场价格受供给和需求影响,建立一种新型的动态价格下的捕获模型,并对此模型进行了动力学分析.在经济意义下,如果捕获相同数量的生物种群,那么在均衡价格下的捕获努力量会低于常数价格下的捕获努力量,这将为如何降低捕捞成本提供有价值的理论借鉴.

We established a new harvesting model with dynamic price under the condition that market price was influ-enced by supply and demand and the dynamics of this model was analyzed.In the economic sense,harvesting effort under e-quilibrium price will be less than that under constant price if fishing the same number of population,it will provide a valuable theoretical guidance in how to reduce the cost of fishing.
