【摘要】 应用植被样方调查法研究了广东英德石门台保护区内木龙顶地段的广东松群落的物种组成、科的地理成分和种群年龄结构.结果表明,在4 800 m2样方中,有维管植物169种,隶属于59科.群落数量优势科为壳斗科、杜鹃花科、樟科、山茶科等,植物科的地理成分以泛热带和北温带分布型等占优势,体现了南亚热带向中亚热带过渡的特点.种群立木的年龄结构表明广东松属于相对稳定种群,但乔木层其它物种的幼苗数量较多,更新竞争激烈.更多还原

【Abstract】 Ecological characteristics of Pinus kwangtungensis community at Mulongding,Shimentai Nature Reserve,Guangdong,were studied by using the method of quardat.There are 169 species of vascular plants belonging to 59 families in a sampling area of 4 800 m~2.The dominant families of community are Fagaceae,Ericaceae,Lauraceae,and Theaceae,etc.Most of the floristic elements of family are Pan-tropical and North temperate distributing types,which shows the character of transition of south subtropical and mid-subtropical elements.Analysis on the age structure of the population indicated that Pinus kwangtungensis expressed a relative stable stage.It would be dramatically competition in the future because of the large seedling amounts of other species in the generation layer.更多还原
