| Abstract: | In this paper,by sample plot methods and community survey,19 typical sample of the Beichuan River nature reserves were investigated,Beichuan River nature reserve species richness of plant communities,species diversity index,species diversity index and evenness index gradient in the distribution of community were calculated and analyzed,the change law of species diversity were revealed to provide information and theoretical basis for vegetation and its recovery update. |
