自治单种群模型及其最优捕获策略

AUTONOMOUS SINGLE-SPECIES MODELS AND THEIR OPTIMAL HARVESTING POLICIES

本文用一种新的方法,讨论了单种群生物资源的捕获优化问题.分别以单位时间最大可持续捕获量和单位时间最大净利润为管理目标,得到一类自治单种群捕获模型的最优捕获策略,所得结果包括了文献中研究过的几乎所有自治单种群捕获模型的相应研究结果.

In this paper, using a new method, we discuss the optimal harvesting problems for single-species biological resources. We choose the maximum sustainable yield and net revenue as the management objectives, and investigate the optimal harvesting policies for a class of autonomous single-species models. Our results include almost all the autonomous single-species models ever researched and reported in the literature.
