Abstract

In this article, a nonlinear mathematical model is constructed to investigate the conservation of depleted forest resources due to the increase of population and associated pressures. Fundamental equations governing the dynamics of the system are defined by the set of highly nonlinear ordinary differential equations and solved numerically. The model is analyzed by using the nature of stability analysis theory of dynamical system. The numerical solutions and simulations of the system are carried out using ODE45 subroutine of MATLAB. Presentations of results are revealed using graphs and interpreted biologically. It is noted that the increase of population density and associated pressures causes the depletion of forestry resources. However, forest resources can be conserved by controlling man made fire, toxicant activities, applying economical incentives and technological efforts.

枯竭林业资源保护的数学模型

本文建立了一个非线性数学模型，探讨了人口增长和相关压力对枯竭森林资源保护的影响。控制系统动力学的基本方程由一组高度非线性常微分方程定义并进行数值求解。利用动力系统稳定性分析理论的性质对模型进行了分析。利用MATLAB的ODE45子程序对系统进行了数值求解和仿真。结果的展示用图表显示，并进行生物学解释。人们注意到，人口密度的增加和有关的压力造成了森林资源的枯竭。但是，森林资源可以通过控制人为火灾、有毒活动、采用经济奖励和技术努力来保护。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
