Abstract:
To understand Lophatherum gracile plant community's structural characteristics, a survey of community structure and species diversity was conducted through quadrat sampling in Yongchuan district of Chongqing. The results showed that there were 386 species vascular plants, belonging to 117 families and 229 genera. Based on habitat, community structure and species composition, L. gracile were found in three community types: Pinus massoniana community, banboo community, shurb community. Vertical structure was composed of three layers, including tree layer, shrub layer and herb layer. Species in shrub layer was the richness. P. massoniana is the only dominant species of the community, it can not regenerate naturally, the shrub layer has a greater effect on the community of L. gracile in the future. In addition, the banboo community and shurb community is not stable because of human's activity. Therefore, the community characters of L. gracile should be taken care of conservation when the resources are utilized.
