Tính đa dạng loài và sinh khối rừng biểu thị cho sự ổn định của hệ sinh thái rừng nói chung và hệ sinh thái rừng lá rộng thường xanh nói riêng. Bài viết trình bày mối quan hệ giữa đa dạng loài và sinh khối của rừng lá rộng thường xanh ở miền Trung-Tây Nguyên. | Trường Đại học Nông Lâm TP.

This study was carried out in three different geographical regions Accepted February 17 2022 of the Central-Central Highlands region namely Quang Binh Thua Thien Hue and Gia Lai. The study used survey data of all small-diameter trees from 03 large size plots to study the relationship between species diversity Keywords phylogenetic diversity and above-ground biomass. The indices of species diversity phylogenetic diversity and terrestrial biomass were calculated and compared statistically. The results showed that i There was a sig- Above-ground biomass nificant difference in species diversity between the study plots ii Phylo- Central highlands genetic clustering and overdispersion were found in the study plots iii Phylogenetic diversity There was no significant correlation between species diversity and above- Species diversity ground biomass in all three study plots. In brief these results indicate that Tropical evergreen forest habitat factors have affected the diversity and phylogenetic diversity of the studied forest plant communities. In addition futhur studies are needed Corresponding author in the direction of combining habitat factors such as climate topography and soil with forest succession stages to find out the correlations between Nguyen Hong Hai biotic factors and infertile.
