价格随供求变化的竞争扩散系统捕获模型(I)

Harvesting model of the competitive diffusive system with the price changed along with demand and supply (I)

研究具有扩散的竞争生物系统,建立了价格随供求变化的经济捕获模型,并对模型进行了详细分析;讨论了扩散对生物系统的影响,从经济学和生物学角度求出无扩散时开放式捕获所遵循的自然规律.

Harvesting model with the price changed along with demand and supply is established for the competitive diffusive system.By analyzing deliberately with the model,on the one hand, the impact of diffusion on the system is obtained and on the other hand,under the condition of no diffusion in the system,the natural law which the harvesting should follow is deduced,from the view angle of the biological and economic significance.
