摘　　要：采用随机样地调查法,对福建省建宁闽江源国家级自然保护区钟萼木群落进行调查,结果表明:该群落物种较丰富,共有植物39种,隶属于26科34属;Shannon-Wiener多样性指数为1.89,Pielou均匀度指数为0.33,Simpson生态优势度指数为0.52;钟萼木在该群落中处于优势种地位,其伴生物种较丰富,但伴生树种间的关系不稳定。Taking the random sampling survey method, the community structure and species composition of community of Bretschnei- dera sinensis were investigated in Minjiangyuan Nature Reserve, Jianning county, Fujian Province. Results showed that the species composition was complex. There were 39 species belonging to 26 families,34 genera in the community. Shannon-Wienner index was 1.89, Pielou index was O. 33 and Simpson index was O. 52. Bretschneidera sinensis was the dominant species in the community. The concomitant species were abundant, but the relationships among Bretschneidera sinensis and its concomitant species were unstable.
