摘  要：
在浙江省临安区於潜镇南山村实验林场,设置毛竹林、6年生毛竹萌芽杉木混交林（简称竹杉混交林）、毛竹萌芽杉木混交林去除毛竹后形成的杉木林（简称去竹杉木林）、萌芽杉木林（简称杉木林）4种林分试验林,探究毛竹入侵及去除对杉木林林分结构和群落物种多样性的初期影响.结果表明:（1）竹杉混交林中树高H>3 m以及胸径D>7.5 cm的杉木比例显著低于杉木林中的杉木比例,去竹杉木林中杉木的平均树高和平均胸径都大于混交林,但小于杉木林.（2）去除毛竹1 a后,杉木林灌木层物种丰富度和优势度都显著增加,而草本层的物种数量和优势度都显著降低,但去除毛竹对灌木层和草本层物种均匀度未产生明显影响.

摘  要：
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.
