Higher plants species diversity in different types of artificial broad-leaved Korean pine forests

Abstract

Abstract: Employing Shannon-Wiener index,evenness,and dominant index,this paper studied the species diversity of 20-yr artificial pure and mixed broad-leaved Korean pine forest stands in eastern Liaoning Mountains.The results showed that mixed forest had a higher biodiversity than pure forest.The species and their total amount in pure Korean pine forest was 42%～52% and 11%～37% of mixed forest,respectively,and the species diversity of artificial broad-leaved Korean pine forest was higher than that of pure forest but lower than that of natural broad-leaved Korean pine forest.Artificial broad-leaved Korean pine forest had more layers with complicated structure and diversity in vertical layer,while pure Korean pine forest only had one main layer with lower shrub and herb layers,which made the vertical structure simple.
