| 摘 要： | 生态学的数学模型中最简单的是只考虑一个种群的生长过程。若假定在瞬时间δt中,每一个体产生的新个体数为αδt,于是得到描述单个种群增长的数学模型 dN=Nαdt=αNdt,α>0 (1)式中N是时间t时种群的个体数,而α为内禀(Intrinsic)增长率,这方程的解为 N=N_0e~(αt) (2)

| Abstract: | In this paper we have reviewed the simplest stochastic growth model of single-species populationdN=aNdt+NdB (3)where B(t) is a wiener process. It was obtained by Maywe considered the other stochastic growth model(7)where X(t) is a Gaussian stationary process.We have analysed and compared their character and relation |
