摘要: 本文我们将研究三物种组成的食物链模型，考虑各个物种在空间中的随机迁移，建立反应扩散型偏微分方程，通过数值模拟来研究种群的演化，并结合理论分析对种群演化的观测结果进行定性的解释。
Abstract: In this paper, we will study the food chain model of the three species, consider the random migra-tion of each species in space, establish reactive diffusion partial differential equations, and study the evolution of the population through numerical simulation. The qualitative interpretation of the observation results of population evolution is carried out in combination with theoretical analysis.
