摘要
用生命表法对天童国家森林公园主要常绿阔叶树种叶子的寿命进行了研究,结果表明:大多数常绿阔叶树种叶子的寿命在1~3年之间,且变化幅度较大;就平均值来看,小乔木及灌木的叶子寿命较长,中乔木叶子的寿命较短;在演替过程中,组成演替早期群落的物种叶子寿命较短,而后期群落的植物叶子寿命较长。文中还就叶子寿命和常绿阔叶林的结构及动态机理进行了讨论。
Leaf longevity of the main evergreen broad-leaved species of Tiantong National Forest Park was studied using the life-table method. The results are as follows: leaf longevity was 1-3 years for many evergreen broad-leaved species, but variation was larger among species than between species. Average leaf longevity was longer in small trees and shrubs than in large trees. Longevity of leaves of species in early community stages was relatively short but become longer in later stages through a succession series. The relations of leaf longevity and structure and dynamics of evergreen broad-leaved forest are discussed in this paper.
