| 摘 要： | 通过对种群规模的消长及种群格局在生态场中变化过程的分析，结合混沌科学的研究成就，文章讨论了种群动态中的非线性问题。分析表明，ｒ－对策种群动态是一个较为开放的耗散系统，其种群涨落并非简单的无序；ｋ－对策种群在生态场四维空间之中，由于混沌因子的作用及作用过程的非线性动力学性质，其种鲜动态也并非简单的线性调控。

| Abstract: | Based on the analyses of the changes about sizes and distribution patterns of population in the ecological field,and on the chaos science,thc paper deals with the non-linear phenomenon in population dynamics. The results show that the dynamics of r-population is one of dissipational systems,and its Changes are not simple non-orders. Because of chaosfactors and their non-linear characteristic in the ecological field,t,he k -population is not a simple linear controled population. |
