摘要
本文通过对森林群落立木种群年龄结构的研究,认为:N_1初生正常种群和N_2旺盛种群的年龄结构各具2种类型,N_3成熟种群的年龄结构仅具1种类型,S_1始衰种群的年龄结构具19种类型,S_2中衰种群的年龄结构具5种类型,S_3老衰种群的年龄结构具2种类型。依此,本文讨论了森林群落立木种群的动态规律。
The population age structure of standing-trees is studied and the results are that initial normal populations and vigorous populations possess two subclasses, adult populations possess only one subclasses, initial senescent populations possess nineteen subclasses, mid-senescent populations possess five subclasses and final senescent populations possess two subclasses. Finaly, the population dynamic of forest community is discussed.
