| Abstract: | The vegetation data of natural Pinus tabulaeformis forest in Songshan,are usedas the information for ecological analysis.①The flora componesnts of this community arestudied by analyzing the composition of 35 families,73 genera and 91 species.Most of region-al types of genera originated from North temperate zone.②The diversity and evenness ofthe tree,shrub and herb species are tested by Shannon-Wiener index,and the results are 0.914 6 and 58.35%,2.145 6 and 76.62%,2.785 7 and 63.62%respectively.③The Raunki-aer systems of biological spectrum is used to describe the extraform of the community,④The vertical stratification of the forest is very obvious. |
