Abstract: The species composition and structural characteristics of Pinus bungeana community of National Forest Park of Wulu Mountain were studied by the sample-plot survey method. The results showed that 61 species belonging to 32 families and 45 genera were recorded in the plots. Among the 61 recorded species, 3 species are gymnosperms belonging to 2 families and 2 genera, 58 species were angiosperms belonging to 30 families and 43 genera. Data on species abundance, mean DBH and important value indicated that the dominant species were obvious within community. The communities had a complex vertical structure and were divided into arbor layer, shrub layer and herb layer. The arbor layer could be divided into three sub-layers. The species group of Pinus bungeana were the dominant population in the community, which appeared in each sub- layer. The size-class structure of all species in the plots generally conformed to a reverse “J” distribution. The size-class structure of several dominant species could be divided into three types: a reverse “J” distribution, bimodal distribution and a reverse “W” distribution.
