以群落学的调查方法,对福建武夷山脉13个研究地、4.86 ha样方开展实地调查。通过统计分析,结果表明:武夷山脉裸子植物群落物种组成丰富,维管植物有482种,其中蕨类植物58种、裸子植物39种、种子植物385种。分布于武夷山脉的81个裸子植物群落隶属1个植被型组,4个植被型,4个植被亚型,17个群系组,27个群系。群落的特有性比例高达86%,如南方铁杉林、黄山松林、刺柏林、南方红豆杉林、长叶榧树林等均为我国宝贵的自然资源。暖温性裸子植物群落分布在中低海拔(450 m~1 000 m),温性裸子植物群落分布在中高海拔(800 m~1 800 m);裸子植物群落的数量分布变化从南至北呈现递增趋势。

Base on community survey methods,the field surveys(13 studied sites,4.86ha plots) were carried out in Wuyi mountains,Fujian province.Through statistical analysis,the results showed that: plants species was rich in gymnosperm communities,there were 482 vascular plant species,of which there are 58 ferns species,39 gymnosperm species,385 seed plant species.There were 81 gymnosperm communities located in Wuyi mountains,which belonged to 1 vegetation type groups,4 vegetation types,4 vegetation subtypes,17 formation groups and 27 formations.The proportion of endemic community accounted for 86%,such as Tsuga chinensis var.tchekiangensis forests,Pinus taiwanensis forests,Juniperus formosana forests,Taxus wallichiana var.mairei forests,Torreya jackii forests,etc.which were precious natural resources in China.Warm-temperate gymnosperm communities were distributed in low altitude(450m-1000m),Temperate gymnosperm communities were located in high altitude(800m-1800m);The quantity change in the distribution of gymnosperms communities showed an increasing trend from south to north.
