Abstract
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.
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。
