Diversity of higher plant in broad leaved Korean pine and secondary birch forests in Liangshui Natural Reserve

Abstract

Shannon diversity index and its evenness are used to analyze the difference of higher plants in broad-leaved Korean pine forest and secondary birch forest. The result show that the species diversity of higher plants in secondary birch forest is higher than that in broad-leaved Korean pine forest. Many of rare species existing in broad-leaved Korean pine forest are few or absent in secondary birch forest. The diversity of herbs both in broad-leaved Korean pine and in secondary birch forest is very rich and has a great change in different seasons.
