天目山自然保护区蛇足石杉生境群落学特征研究

Study on Community Property of Huperzia serrata Habitat In Tianmushan Nature Reserves

浙江天目山自然保护区蛇足石杉所处群落共有种子植物73种,隶属40科,62属,其植物区系的温带特征显著。按Raunkiaer生活型统计,小高位芽植物占44%,中高位芽植物和矮高位芽植物均占16.7%。叶级以小型叶为主,占60.3%。叶型以单叶比例最大,占74%;叶质以草质为优势,占45.2%;全缘叶种类占总种数的50.7%,非全缘叶种类占49.3%。群落结构可分为乔木层、灌木层和草本层。

There were 73 species of seed plants belonging to 62 genera of 40 families at Huperzia serrata habitat in Tianmushan Nature Reserves, Zhejiang province. The flora there was characterized by temperate property. According to Raunkiaer＇s classification, the microphanerophyta accounted for 44%, meso-phanerophyta and nanophanerophyta accounted for 16.7%. The leaf size of the vegetation was mainly microphylla （60.3%）. The proportion of simple leaf was 74%, herbaceous quality leaf was 45.2%, entire margin leaf was 50.7%, and non-entire margin leaf was 49.3%. The phytocoenosis could be structurally divided into arborous layer, shrub and herbaceous one.
