To understand the effect of moso bamboo(Phyllostachys edulis)expansion on the community structure and species diversity of different artificial forests,continuous ecological interfaces from a moso bamboo stand to a Chinese fir(Cunninghamia lanceolata)stand,and broad-leaved forest(dominated by Camptotheca acuminata+Sassafras tzumu)were selected to set transects.The results showed that the density of moso bamboo increased with the expansion to Chinese fir stand or broad-leaved forest,accompanied by an increase in bamboo density but a decreasein the original species.Bamboo expansion changed the c...
