摘　　要：运用耗散结构理论对人口系统的演化问题进行了研究,通过对区域人口最大承载量,人口出生率,死亡率的参数设定和人均增长率公式的设定,引入逻辑斯蒂(Logistic)方程描绘出人口增长的逻辑斯蒂(Logistic)曲线.并在此基础上应用非线性系统的稳定性判据探讨了在可持续目标下的人口数量范围.A study is made on the evolution problem of population using the theory of dissipative structures. By estimating some regional parameters of maximum population capacity, birth rate, death rate, average increase rate and Logistic functions, the logistic curve of population increase rate is achieved. In addition, a discussion is carried on the population range in line with the sustainable development goal by using nonlinear stability criteria for nonlinear system.
