摘要
本文的研究重点是建立由人口密度和工业化引起的森林砍伐模型。首先,它被表述成一个数学模型,它是一个非线性微分方程系统。然后,根据Routh-Hurwitz稳定性准则分析了系统的稳定性。此外,还进行了数值模拟以确定系统的位移。分析结果表明,非负平衡点有7个,一般分为无扰动平衡点和有扰动平衡点。对平衡点TE7(x, y, z)进行分析,得到基于Routh-Hurwitz稳定性准则的渐近稳定条件。数值模拟结果表明,在满足系统稳定条件的情况下,系统的运动总是发生在平衡点附近。
Mathematical Modelling of Deforestation Due to Population Density and Industrialization
The focus of the study in this paper is to model deforestation due to population density and industrialization. To begin with, it is formulated into a mathematical modelling which is a system of non-linear differential equations. Then, analyze the stability of the system based on the Routh-Hurwitz stability criteria. Furthermore, a numerical simulation is performed to determine the shift of a system. The results of the analysis to shown that there are seven non-negative equilibrium points, which in general consist equilibrium point of disturbance-free and equilibrium points of disturbances. Equilibrium point TE7(x, y, z) analyzed to shown asymptotically stable conditions based on the Routh-Hurwitz stability criteria. The numerical simulation results show that if the stability conditions of a system have been met, the system movement always occurs around the equilibrium point.
