考虑单种群的Logistic方程,在R+中都存在均值的意义下,选择单位时间的最大持续收益的极限值作为管理目标,从而得到最优的种群水平.
The single population modeled by logistic equation is considered in this paper, by all have average value in, we choose the average limiting maximum sustainable yield per unit time as management objective, the corresponding optimal population level is determined.
