摘　　要：通过对人工控制森林生态系统的分析 ,得到了在红松种子、鼠类与幼苗三种群数量具有周期波动的条件下 ,适当地采集松籽不会影响生态系统的稳定性 .这样不但可以调节三者之间的关系 ,保持生态平衡和种群的持续发展 。Analysis of the artificial controlling system shows, when the periodic fluctuations among the amount of the seed、 squirrel and seedlings exist, it would never influence the stability of the ecological system with collecting seeds or catching squirrels properly. It can adjust the relationship, keep ecological balance and the continuous development of the population and improve economic benefits.
