摘要
首先介绍了种群在理想状态下的几种增长模型,接着研究了在有限池塘中两种存在捕食关系的鱼类之间的数学模型。计算出平衡点并分析其稳定性,根据仿真模拟试验得出,一定空间内的种群在经过一段时间后,种群的数量趋于稳定,达到生态平衡。
This paper first introduces the population under the ideal state of several growth models, and then study the finite pond exists two kinds of predator-prey relations between fish of mathematical model. To calculate the equilibrium points and to analyze its stability, according to the simulation experiment, a space within a population over a period of time, population tends to be stable, achieve ecological balance.
