Abstract: Plant community of Prunus divaricata Ledeb.was studied.There are 98 species of vascular(including varieties),which belong to 36 genera and 84 families,based on data from 32 plots and 64 the size of 1m×1m little plots.The importance value of the wild hawthorn,the wild myrobalan plum,the wild apple and the wild apricot are highest,their importance value are 42.79,33.78,30.21 and 22.94.Comparative Study of the same growth form and species diversity we found the Margalef index,the Simpson index and Shannon-W inner index show that the species richness order was that the herb layer shrub layer tree layer.The species richness of the herb layer show close relationship with the total species richness of community.The ecological environment of Prunus divaricata Ledeb.plant communities is fragile.The strategies for conservation should be Strengthened.
