利用微分包含给出了两种群捕食-被食系统收获模型的一种新的表达式,其优点是可以不考虑模型中参数的具体形式.基于生存理论,通过求解一维优化问题给出了将两种群数量控制在某范围的条件.
A new two species predator-prey system harvest model is given by means of differential inclusions. The advantage of this model is that the expression of parameters will not be considered. Based on the viability theory and solving one-dimensional optimization problems, the conditions of controlling the numbers of two species in a certain range are given.
