摘要

通过设置临时标准地对龙栖山、武夷山和天宝岩3个国家级自然保护区的3种毛竹混交林群落类型结构进行调查与统计分析。结果表明,在物种数量上从多到少依次为:武夷山国家级自然保护区的毛竹+少叶黄杞(Phyllostachys pubescences Mazel ex H. Delehaie +Engelhardtia fenzelii Merr.)混交林(68科125属230种)、龙栖山国家级自然保护区的毛竹+南方红豆杉〔Taxus chinensis (Pilger) Rehd. var. mairei(Lemeeet Lévl.) Cheng et L. K. Fu〕混交林(69科135属194种)和天宝岩国家级自然保护区的毛竹+长苞铁杉(Tsuga longibracteata Cheng)混交林(41科71属105种)。3个毛竹混交林群落结构分明,毛竹在混交林群落乔木层中占绝对优势的地位。乔木层、灌木层和草本层层次清晰,还具有层间层。毛竹+南方红豆杉群落和毛竹+长苞铁杉群落乔木层可分为3个亚层,而毛竹+少叶黄杞群落乔木层可分为2个亚层。毛竹+少叶黄杞群落的灌木层物种数和草本层盖度均比其他2个群落高。

Abstract

Based on the data collected from sample plots, the community structure features of the mixed forest of Phyllostachys pubescences Mazel ex H. Delehaie in three national nature reserves of Fujian Province were researched and analyzed. The community P. pubescences + Engelhardtia fenzelii Merr. in Wuyi Mountains NationalNature Reserve consists of 68 families, 125 genera and 230 species. There are 69 families, 135 genera and 194 species in the mixed forest P. pubescences+ Taxus chinensis (Pilger)Rehd. var. mairei (Lemee et Lévl.)Cheng et L. K. Fu in Longqi Mountains National Nature Reserve, and 41 families, 71 genera and 105 species in Tianbao Rocks Nature National Reserve(P. pubescences + Tsuga longibracteata Cheng).The stratification of the vertical structure of the three plant communities isobvious, P. pubescences is absolutely dominant in tree stratum. The communities have three main layers including tree stratum, shrub layer and field layer, and inter-layer as well. The tree stratum of the communities in P. pubescences+ Taxus chinensis var. mairei and P. pubescences+ Tsuga longibracteata consist of three sub-layers, and only two sub-layers in the P. pubescences+ E. fenzelii community. The species of shrub-layer and the cover rate of herb-layer in the P. pubescences+ E. fenzelii community were more than the other two's.
