摘要
以《资源—经济可持续发展的最优经济发展模型》中模型的动态方程为基础,重点研究资源的恢复性投资对可再生资源的可持续利用的影响,应用非线性动力学方法研究了系统正不动点的存在性、局部稳定性,然后用数值模拟的方法验证了正不动点的局部稳定性,最后应用全局分析方法给出了维持资源可再生能力的当前资源存量范围(可行吸引域)。
Based on the dynamical equation for the model presented in paper [3], this paper fo- cuesd on the influence of resource investment on the sustainable utilization of the resources. The existence and the local stability of the positive equilibrium were investigated by the use of the nonlinear dynamics. Then the local bifurcations of fixed points were verified through the numeri- cal simulation. Finally, the extension of current stock in which resource can be renewable （feasi- ble domain） was given by global method.
