野生人参自然分布的典型原始阔叶红松林群落及其特征研究

本文通过物种多样性指数、生态优势度、群落均匀度、重要值等指标综合分析了野生人参自然分布的典型椴树阔叶红松林的群落特征．结果认为椴树阔叶红松林内物种数及其个体数量较多，多样性指数及群落的均匀度都较高，物种分布均匀并具有明显的层次，生态优势度较低，具有较稳定的群落结构．这种群落特征给人参的生活和生长创造了适宜的生态条件，是人参这一古老遗植物在这种群落中得以长期保存和生长繁衍的主要因素．

STUDIES ON TYPICAL PRIMITIVE BROAD-LEAVED PINUS KORAIENSIS FOREST COMMUNITY IN WHICH WILD GINSENG DISTRIBUTES NATURALLY AND ITS CHARACTERISTICS

This paper comprehensively analyses the community characteristics of typical Tilia broad-leaved Pinus koraiensis forest in which wild ginseng distributes naturally by means of species diversity index, ecological dominance. the evenness of community and important valuses. The result shows that there are many species and its individuals in Tilia broad-leaved Pinus koraiensis forest, the species diversity index and the evenness of community are also very high, species are well-distribute and have evident layers, ecological dominance is so low that the forest has steady community structure.This kind of community characteristics that provide suitable ecological environment for ginseng's growth are also main reason for ginseng-the plant left over from ancient bines to live and be preserved for a long time in the community.
