摘  要:
对丽水市白云山人工林群落设置标准样地进行生长量和生物量调查。林分径阶分析显示,20年生马褂木(Liriodendron chinense)和24年生福建柏(Fokienia hodginsii)径阶集中在14~18 cm,径阶分布较集中,22年生日本冷杉(Abies firma)径阶具明显的双峰结构,林分总蓄积为马褂木(347.62 m3/hm2)>日本冷杉(175.31 m3/hm2)>福建柏(127.79 m3/hm2);连年生长量分析表明,马褂木胸径的连年生长高峰在第8~12年,在第10年达到最高峰,福建柏分别在第12年和第16年出现2个生长高峰,马褂木前期生长速度明显高于其他2个树种,但之后生长速度下降较快。马褂木人工林生物量比福建柏人工林高176.61%、比日本冷杉人工林高42.15%。在各人工林乔木层总生物量中,干材(包括树皮)最大,其中尤以马褂木干材比重最大,为68.43%,对以收获木材为主要经营目标的人工林来说,马褂木相对于福建柏和日本冷杉,具有较大的木材收益。

摘  要:
Investigation was conducted on increment and biomass of artificial Liriodendron chinense,Fokienia hodginsii and Abies firma forest on Baiyunshan Mountain,Zhejiang province.Analysis on DBH distribution of the forests demonstrated that 20-year L.chinense and 24-year F.hodginsii was aggregated between 14-18cm,while 22-year A.firma had evident two peaks.Volume-increment of whole woods of L.chinense(347.62m3/ha)> A.firma(175.31m3/ha) >F.hodginsii(127.79m3/ha).Current annual DBH increment of L.chinense was fast during the 8th to 12th year and topped in the 10th year,that of F.hodginsii had two peaks in 12th and 16th year.Biomass of L.chinense forest was higher by 176.61% and 42.15% than that of F.hodginsii and A.firma forest.In the total biomass of the three forests,stemwood(including bark) took the biggest part,especially that of L.chinense accounted 68.43%.
