摘　　要：为了提高画稿溪国家级自然保护区珍稀濒危植物小黄花茶的保护效果,采用样方调查法对其群落特征和种群结构展开调查.结果表明:(1)画稿溪小黄花茶种群为增长性种群;(2)样方中共有34科41属48种植物,其中乔木层23科30属34种,灌木层有16科18属19种,草本层5科5属5种,群落中的优势种为小黄花茶、川鄂连蕊茶、滇润楠;(3)群落郁闭度较大,林下光照弱,幼苗无法健康生长是小黄花茶自然更新受阻的主要原因.In order to strengthen the conservation effect of Camellia luteoflora which is a national rare and endangered protected plant in Huagaoxi National Nature Reserve,the community characteristics and population structure of it were investigated by means of sampling method.The results show:(1)the population of Camellia luteoflora is a growing population;(2)there are 34 vascular plats belonging to 41 families and 48 genera in the community with 23 families,30 genera and 34 species in the arbor layer,16 families,18 genera and 19 species in the herb layer,and 5 families,5 genera and 5 species in the herb layer plants,the predominant species in the community are Camellia luteoflora,C.rosthorniana,Machilus yunnanensis;(3)the community depression degree is large,the forest light is weak,the inability of seedlings to grow healthily is the main reason for the blocked natural renewal of Camellia luteoflora.
