建立了生长率与捕获努力量均受到白噪声干扰的两种群随机时滞竞争模型,利用随机分析理论得到了种群灭绝与在均值意义下持久的充分条件,并给出数值模拟以验证所得到结果.
Dynamic analysis of a class of stochastic competition model with time delay
A stochastic time delay competition model for two populations is established in which both population growth rate and harvesting effort are affected by white noise.The sufficient conditions for extinction and persistence in mean are obtained by using stochastic analysis theory.Numerical simulation is given to verify the results.
