摘要
本文研究了Logistic模型在渔业收获中的应用.我们脉冲的在湖泊中增加鱼的食物(水草),以此来增大湖泊的环境容纳量.因此,经过一段时间后,鱼的数量可以达到一个很高的水平.我们从生态和经济学的角度出发,找到了最优策略,通过例子(表1-表10)给出了具体的策略.在最后一个例子(表11)中,我们比较了参数A和T对模型的不同影响.最后,我们指出了本文的数学和数值模拟结果在生态学和经济学中的应用,并且作了简短的讨论.
In the paper, a Logistic model is studied for its application in fish harvesting. We impulsively put additional food （aquatic） into the lake to enlarge the carrying capacity. Thus, after a period of time, the amount of fish can reach a high level.We get the optimal strategy [rom the view point of ecology and economics. Our examples （Table 1-Table 10） give the detailed strategies. And the last examples （Table 11） compare the effects of different A and T. In the last, we interpret our mathematical and simulated results for ecological and economical application, and a brief discussion is presented.
