Research on Community Structure and Species Diversity of Larix gmelinii Community in Inner Mongolia Daxing’anling Mountains

Abstract

Abstract: Based on the field investigation of 3 sample plots of Larix gmelinii in Chaoer of Inner Mongolia,this paper analyzed the tree species composition structure,diameter and height structure,distribution patterns and species diversity.The results showed that:(1) SampleⅠand sample Ⅲ were all pure forest of Larix gmelinii. The density is 740 No./hm² and 380 No./hm².sampleⅡwas mixed forest of Larix gmelinii,Betula platyphylla,Betula dahurica Pall and Davidiana dode.The density is 1080 No./hm².(2)The pure forest of Larix gmelinii (sampleⅠand sample Ⅲ) was in regular distribution,the mixed forest(sampleⅡ) was aggregated distribution.(3)The species richness and species diversity index in the community vertical structure are:herb layer >shrub layer >arbor layer.

Key words: community structure, distribution patterns, species diversity, Larix gmelinii, Inner Mongolia Daxing’anling Mountains
