Landslide is a common geological hazard and mainly triggered by heavy rain storm or earthquake in Wolong mountainous region. In this paper the vegetation of 11 landslide areas after five-year of natural restoration were investigated using quadrat method in Wolong nature reserve. Moreover, the species composition, floristic element and pioneer species of the secondary communities were analyzed, and an artificial restoration area was chosen as the control. 44 families and 103 genera of 119 plant species, including 29 species of shrubs and 90 species of herbs were detected, including 18 new species which had not been recorded before. Angiosperm was dominant in numbers of families, genera and species. The geographical elements of detected 39 families of seed plant at the early stage of the natural restoration mostly were cosmopolitan out of five geographical elements. All 98 genera of seed plant were divided into 11 types by their geographical elements. Using genus as the basis of floristic element classification, 90.91% of the seed plant were temperate genera (excluding the cosmopolitan genera), indicating the sample areas were temperate property. The results indicated that the species abundance and community structure of natural restoration areas were superior to the artificial recovering area. The dominant pioneer species of shrub layers and herb layers of different natural restoration landslide areas were ascertained via the analysis of importance value. This research provides scientific basis for candidate native species could be used in ecological artificial vegetation restoration in Wolong nature reserve areas in future.
