鄂西南百户湾针阔混交林群落结构与多样性研究
Study on Community Structure and Diversity of Mixed Coniferous and Broad-leaved in Baihuwan of Southwest Hubei
摘要
Abstract
In order to investigate the changing law of community structure and species diversity in the process of natural turnover of forests with artificial management background after closure and protection,a 0.01km2 mixed coniferous and broad-leaved forest fixed monitoring sample plot in Baihuwan forest farm in southwest Hubei was used as the research object to investigate and analyze the species composition,community structure and species diversity of woody plants.The results showed that:8702 woody plants with the diameter at breast height(DBH)≥1 cm,belonging to 111 species in 66 genera of 39 families,were found in the sample site;among the top 10 species in terms of importance value,broad-leaved evergreen species dominated;the dominant species in the canopy layer were Cunninghamia lanceolata and Quercus serrata,and the dominant species in the shrub layer was Eurya alata;the number of individuals in the sample decreased gradually with increasing DBH value,and there were more individuals in the small diameter class,with an average DBH of 5.2 cm;species richness was observed in the sample site,and the highest species diversity was found in the subtree layer among the various strata.This study provided a scientific basis for further investigating the dynamic changes of forest community structure and species diversity.关键词
