有密度制约的Lotka-Volterra模型互惠系统同时捕获的最优化

Optimal problem of density constrain Lotka-Volterra model mutually beneficial system harvested simultaneously

对有密度制约的Lotka-Volterra互惠系统的平衡点进行了定性分析,从生态学意义上给出了解释.此外分为已知正常数和未知两种情况给出了此系统的两种群同时捕获时的最大持续受益的条件。

This paper makes an qualitatiye analysis of the equilibrium of density constrain Lotka-Volterra model mutually beneficial system and gives the explanation from the ecology meaning.In addition,the article gives the conditions of maximum sustainable economic revenue when two species of prey-predator systems are harvested simultanously.
