摘要
本文考虑了具有污染与捕获的互惠种群生存的动力学模型,应用微分方程的比较原理,得到种群一致持续生存及灭绝的充分条件,揭示环境污染与种群捕获之间的关系,最后讨论了种群的最优收获策略.
In this paper,the dynamic model of reciprocal population possessing pollution and capture is considered. We applied the theorem of differential equations and obtained the sufficient and extinction of the population. We revealed relationships among environmental pollution and population capture. Finally,we discussed about optimal policy for population.
