摘要
[目的]调查闽北丘陵地区不同杉木人工林林下植被多样性.[方法]以2种不同的杉木人工林(杉木纯林、杉木米槠混交林)林下植被为研究对象,调查灌木层、层间层、草本层的组成及多样性.[结果]杉木米槠混交林灌木层植被共41种,层间层12种,草本层10种;杉木纯林灌木层有21种,层间层6种,草本层12种.[结论]杉木米槠混交林多样性指数高于杉木纯林,发展针阔混交林套种模式有利于杉木人工林的可持续发展.
Abstract
[Objective] To research the understorey vegetation diversity of two types of Chinese fir plantations in northwestern Fujian.[Method] With understorey vegetations of two types of Chinese fir plantations (mixed plantation of Chinese fir and Castanopsis carlesii,pure plantation of Chinese fir) as the research materials,the composition and diversity of shrub layer,interlayer layer and herb layer were investigated.[Result] As for the mixed plantation of Chinese fir and Castanopsis carlesii,there were 41 vegetation species in shrub layer,12 vegetation species in interlayer layer,and 10 vegetation species in herb layer.As for pure plantation of Chinese fir,there were 21 vegetation species in shrub layer,6 vegetation species in interlayer layer,and 12 vegetation species in herb layer.[Conclusion] Species diversity index of the mixed plantation of Chinese fir and Castanopsis carlesii is higher than that of pure plantation of Chinese fir.Development of the interplanting pattern of mixed broadleaf-conifer forest is conducive to the sustainable development of Chinese fir plantation.
