摘要
随机Gilpin-Ayala方程其用幂函数的表达式来更好的刻画各种密度制约机制,具有一般代表性,本文以随机微分方程理论和统计学方法作为工具,探讨随机种群生态模型Gilpin-Ayala方程在It随机积分意义下的正解存在唯一性和参数估计问题.
Stochastic Gilpin-Ayala equation is generally representative owing to use power function to better characterize the expression of various density control mechanism. So this article which is by the theory of stochastic differential equations and statistical methods dis- cusses two points:one is existence uniqueness of positive solutions of stochastic population e- cology model;the other is parameter estimation of the model.
