Abstract:: Natural recovery of vegetation and habitat conditions (including altitude, soil temperature, humidity and salinity) were investigated by sample method in Xiejiadian of earthquake disaster areas in 2014, and we analyzed the correlation of species diversity in each sample and different effects of vegetation restoration of different recovery duration. We can grasp the plant succession pattern of earthquake-affected areas through the study of dynamic vegetation recovery effect and the influence of site conditions, so as to provide reference for local vegetation recovery plan formulation. The results showed that: (1) there were 84 species of plants in this area, tthese plants belong to 66 genera and 46 family, according to the important value, Alnuscremastogyne is the dominant species (0.29), but also is the constructive species in communities, the entire type of community is A. cremastogyne+Rubustephrodes+Equisetum hyemale; (2) in 2014, Shannon-Weiner index (H’), Margalef index (M_a), Pielou index (E) and Simpson index (D) were 2.06, 2.942, 0.73 and 0.189, respectively, the species richness index was rising, and species evenness index was falling compared with 2009; (3) Shannon-Weiner index, Pielou index and Margalef index in different life forms were the biggest in the herb layer, smaller in tree layer, and the smallest in shrub layer; Simpson index is the biggest in shrub layer, second in herb layer, and the smallest in tree layer, uneven distribution of species in shrub lager; (4) plant growth and species composition are affected by soil temperature, moisture and salinity, which influences the species diversity index, the plant species number is increasing dramatically in the recent years, but the species distribution is not uniform in the plot.
