摘　　要： 通过对秦岭华山松林的野外调查,分析研究了该群落的特征和性质.结果表明:秦岭林区华山松群落主要分布于海拔1100～2100m的中山地带;华山松群落内物种相当丰富,共有81科174属346种;落叶阔叶乔木与落叶阔叶灌木在群落中占很大的比例;群落中草质叶型的植物260种,占80.5%,表明群落的落叶性;华山松群落中乔木层、灌木层、草本层的大多数比较常见的属都属于北温带分布,表明群落植物区系组成的温带性质. Community characteristics of Pinus armandii forest on the Qinling Mountains are analyzed by field survey.The results are as followed:community of Pinus armandii in the Qinling Mountains mainly distributes at the latitude of 1 100～2 100 m;phytogeographical elements of the community are very plentiful.There are 81 families,174 genera and 346 species in the community.Deciduous broadleaf trees and shrubs occupy prodigious proportion;260 species whose leaf-texture is herbaceous,occupy 80.5% of the total in the community.It is clear from the figures that deciduous species play an important role in the community.From the facts that most familiar genera of tree species,shrub and herbs belong to north temperate distribution,it can be concluded that community Pinus armandii belong to temperate biome.
