根据林业系统的机理,建立了森林资源消长的非线性动态模型,进行了仿真研究。提出了具有离散延时的非线性系统的Lyapunov指数的计算方法,并用它来判别林业系统中存在的复杂的非线性现象(分歧和浑沌),为协调生态和经济的关系提供了理论依据。
According to the mechanism of forestry system, a nonlinear dynamic model of growth and decline of forest resources was established and simulated. The method to calculate the Lyapunov exponent of nonlinear system with discrete delay is proposed and used to identify the complex nonlinear phenomena (disagreement and chaos) existing in forestry system, which provides a theoretical basis for coordinating the relationship between ecology and economy.
