摘要
本文通过对有关植被调查资料的统计分析得到结果:常绿落叶阔叶混合交林中常绿乔木重要值所占比例范围是8％～75％,落叶乔木重要值所占比例范围是25％～92％。这显然从一个侧面定量给出了常绿落叶阔叶混交林的群落特征。
By analysing the data concerned, Author considers that the importance value proportion of evergreen broad-leaved trees and that of deciduous broad-leaved troes in evergreen and deciduous broad-leadved mixed forest may he defined as follows: 8% <evergreen broad-leaved trees < 75%; 25% <desciduous broad-leaved trees <92%.
