Abstract

Initial effects of Phyllostachys edulis invasion on stand structure and species composition of Chinese fir forest.

Abstract

To elucidate the preliminary impacts of moso bamboo (Phyllostachys edulis) invasion and its clearance on the community structure and species diversity of Chinese fir (Cunninghamia lanceolata), 4 types of forest stands including moso bamboo stand, mixed stands of moso bamboo and Chinese fir, mature Chinese fir stands with P. edulis removed, and juvenile Chinese fir stands were set up on the experimental forest farm in Nanshan Village, Yuqian Town, Lin'an District, Zhejiang Province. The results showed that the proportion of Chinese fir with height > 3 m and diameter at breast height (DBH)>7.5 cm in the mixed forests was significantly lower than that of juvenile Chinese fir stands. The average height and DBH of Chinese fir in mature Chinese fir stands with P. edulis removed were both greater than those of mixed forests but less than those of juvenile Chinese fir stands. After clearing moso bamboo for a year, species richness and dominance of shrub layer increased significantly, while species number and dominance of herb layer decreased significantly. Removal of moso bamboo exerted little effect on species distribution uniformity of shrub layer and herb layer.
