Human activities such as deforestation, cultivation, and overgrazing have contributed to the destruction of forest ecosystems in the upper Minjiang River basin for a long time, which has led to the reduction in forest cover and biodiversity. In the Giant Panda Corridor of Tudiling in this basin, the effects of current disturbance regimes on plant communities after vegetation restoration in 1980’s were assessed and the community composition, species diversity and their relationships with factors significantly associated with disturbances were analyzed by means of transect sampling, two-way indicator species analysis (TWINSPAN) and detrended canonical correspondence analysis (DCCA), The results were as follows: corridor communities could be classified into six types, and species were clustered into four functional groups (response to disturbance, retarded, resistant to intermediate disturbance and resistant to heavy disturbance) based on both TWINSPAN and DCCA. It was similar between DCCA with species composition of plots and that with species diversity of plots. The communities were separated into distinct groups along the DCCA axis and this pattern was significantly correlated with environmental factors. Elevation differences, shape, slope, distance to road and the number of paths in plots influenced the distribution of the species and communities obviously. Slope, distance to road and the number of paths showed the gradient of disturbance among the communities along the DCCA axis. High disturbance intensity caused significantly lower diversity and poor regeneration of restorational vegetation communities compared to the more diverse undisturbed communities. Artificial restoration was better than natural restoration in maintaining high species diversity. The succession was inhibited in natural restoration because of the failure in tree establishment, growth and survival during regeneration.
