摘　　要：福建省是我国石杉科植物资源储量丰富的省份之一，通过全省范围的实地调查，对其资源分布、生境和群落学特征进行了分析．结果表明：福建省分布有长柄石杉、四川石杉、华南马尾杉、柳杉叶马尾杉、闽浙马尾杉和有柄马尾杉等6种石杉科植物，其中长柄石杉分布最广．长柄石杉的适生环境为海拔650--950m、林冠层郁闭度0．5～0．7、土壤腐殖质丰富、空气相对湿度较大的山地北坡、沟谷潮湿的岩石壁上或溪流边疏林下．福建省境内中北部地区长柄石杉的长势和资源储量优于南部地区，山脉迎风坡石杉的长势优于背风坡．通过174个样方调查对石杉科广布种长柄石杉群落特征进行研究，群落共计有维管植物132科353属721种．生活型谱分析显示群落中高位芽植物占优势，占总种数的62．27％，其中又以小高位芽植物最多．群落垂直结构一般分为乔木层、灌木层和草本层三层，灌木层和草本层的物种多样性指数处较高水平，并对长柄石杉的伴生物种进行了分析．Fujian is one of the provinces with the richest Huperziaceae resources in our country. The resource distribution, habitats and community characteristics of Huperziaceae were analyzed based on the survey results. The results show that there are 6 species of Huperiaceae in Fujian： Huperzia serrata var. longipetiolata, H. sutchueniana, Phlegmariurus fordii , Ph. cryptomerianus, Ph. mingcheensis and Ph. petiolatus. Among them, Huperzia serrata vat. longipetiolata has the widest distribution area The suitable environment for Huperzia serrata vat. longipetiolata is at the altitude of 650--950 m, relatively high humidity of the air canopy density of 0. 5--0. 7, in the shade on the hill or in the ravine with wet rich soil, frequently occurs in the steep rock walls or grew under sparse forests beside streams. In Fujian province, the growth vigour and resources of Huperzia serrata var. longipetiolata in the northern area are better than that in the south, and the growth vigor on the windward slope of mountains is better than on leeward slope as well. The community characteristics of Huperzia serrata var. longipetiolata were analyzed based on the data collected from 174 sample plots with a total area of 17 400 m2. The community was composed of 721 vascular species belonging to 132 families and 353 genera The life form spectrum showed that the phanerophytes including the vines take 62. 27% of the total in which microphanerophytes take a dominant position in the community. The vertical structure of community could be divided into tree layer, shrub layer and herb layer. Compare with other communities, the species diversity index of shrub layer and herb layer were in relatively high level. The companion species of Huperzia serrata var. longipetiolata were also analyzed in this paper.
