摘要
本文建立了人类活动与可再生资源的非线性动力学模式 ,研究结果表明 :①所有导致减小可再生资源承载力的人类活动都将导致人口—可再生资源系统作较快的非周期运动 ;②当可再生资源的承载力较大时 ,平衡态的可再生资源总量可以维持在一个较低的水平 ;③平衡态的人口总量与平衡态可再生资源总量成正比 ;④平衡态人口总量、可再生资源总量将随人类富裕程度、科技水平的提高而快速减小 ;⑤环境对人类的惩罚具有滞后性 ;⑥具有高增长率的可再生资源可以承载较大的平衡态人口总量 ,所以 ,保护环境、协调人类与自然的关系、提高可再生资源的增长率对人类自身的发展至关重要。
A nonlinear dynamic model of the human activities and renewable recourses was set up in this paper. The results of study show: ①All the human activities which lead to reducing the bearing capacity of renewable recourses will result in a relatively fast non-periodic motion of the system of people-renewable resources; ②When the bearing capacity of renewable resources is comparative bigger, the renewable resources gross equilibrium state can maintain a relatively lower level;③ The population is proportional to renewable resources in equilibrium state;④The population gross and the renewable resources gross equilibrium state will quickly desrease human affluence and the technological level;⑤There is a lagging time when environment punishes humans for their destruction;⑥The renewable recourse with a high growth rate can bear the comparative bigger population of the equilibrium state, so, it is most important for the development of humans themselves to protect environment, harmonize the relation between man and nature, advance the growth rate of renewable resources.
