摘　　要：以广东4个具有地域代表的风景林下植被为研究对象,采用典型取样调查法,研究了林下植被群落特征。结果表明:林下植被物种组成差异性较大,群落相似性系数表现出极不相似或中等不相似;植物地理区系以热带亚热带成分占优势,从南到北有一定减弱趋势;林下群落优势种具有一定相似性,灌木层优势种以九节、假鹰爪、梅叶冬青、五指毛桃等主;Simposon指数值均较高,林下植被群落多样性较好。Taking the four regional understory vegetation for scenic forest as the research objects in Guangdong province and using typical sampling survey method,the community characteristic of understory vegetation were discussed.The results showed that there were a large differences in species composition of understory vegetation and the community similarity index exhibit extremely dissimilar or medium dissimilar.The tropical and sub-tropical taxa of seed plant flora were predominant and reduce from north to south.Dominant species of understory vegetation had some similarities and the dominant species of shrub layer contain Psychotria asiatica,Desmos chinensis,Ilex asprella,Ficus hirta,and so on.Simposon indexs of sample were all very high and the diversity of understory vegetation for scenic forest were better.
