Relative results which have obtained in [ 1 ] are generalized . results provide theory basis for objective management of renewable biological resources . many objective problems often be trans - ferred to how to find the solution of differential equation ( ode , fde ) 本文在第二部分研究了以gilpin - ayala单种群增长模型为基础,假定生产函数为ex ~ (为正常数)的捕获模型的最优开发问题,确定了最优开发策略,推广了文献[ 1 ]中已有的相应结果,为可再生生物资源的实际管理提供了理论依据。
