Abstract:The characteristics and scientific value of ecological succession in Danxia Landform were discussed in this paper. It was known that researches on vegetation succession were quite difficult for its long-term and intricate process. Space-for-time substitution is an important method to study succession, while it needs intact spatial succession series. In Danxia Landform, there are such primary and secondary succession series. On the hilltops, there are typical low shrubberies and arboreal forests of primary succession. The surrounding slopes are subjected to seasonal rainfall erosion, weathering action, gravitational collapse. The primary succession constantly starts from bare rocks, and then moss and herbage communities. With further weathering of rock and effects of moss and lichen, soil layers are getting thicker and thicker, which pushes primary succession ahead. New collapses are ceaselessly induced by the special geology geomorphological process, and then a new primary succession starts from bare rocks. Thus, different stages of primary succession are formed in Danxia Landform. In addition, the secondary succession series exist in Danxia Landform, including the pioneer forests, transitional forests and basically steady forests. Danxia Landform provides ideal sites for vegetation succession study. And the relative studies would be helpful for the vegetation management and protection in this area. As ecological restoration reference, it is also meaningful for the vegetation restoration.
