摘要: 将沙漠化的土地系统模拟为振子系统,在对Duffing方程讨论基础上,分析了这一特殊振子的结构组成是造成生态系统脆弱的根本原因,并依据混沌振动规律提出了防治沙漠化的步骤和方法。

关键词: 沙漠化, 混沌, 系统, Duffing方程

Abstract: Based on the discussion of Duffing equation, the basic reasons of eco-system fragility caused by the structure of special oscillator is analyzed. By simulating the desertification land as the system of oscillator, according to the theory of choas oscillation, the steps and methods of combating sandy desertification are presented in this paper.

Key words: desertification, choas, system, Duffing equation
