Study on the Speices Biodiversity of Plantation Communities in Primary Korean Pine Forest

Abstract

Species diversity was refers to the rich and colorful differences between biological communities in composition, structure, function and dynamic. In this paper, the 64 pieces of plant community samples as the foundation, From the different types and levels of richness and evenness and species diversity index of Liangshui Nature Reserve, three original Korean pine forest types: korean spruce-korean pine forest (HY); oak-korean pine forest (HZ); linden-korean pine forest (HD), two adjacent artificial forest types: birch pure forest (BH); larch pure forest (LY) studied, conclusions were as follows: vegetation community structure features survey were conducted to identificate 39 species of vasculat plant through analying community species composition which belonging to 32 genera of 22 families. The community species structure was analyed to find that Korean spruce–korean pine community and larch pure community were stable structure; oak-korean pine community was ageing structure. linden-korean pine community and birch pure community were growing structure. The Korean pine forest species richness and evenness no significant difference with artificial forests, species diversity indexes were significantly higher compared with the artificial forests, plant communities less be disturbed, community stability higher than artificial forests.
