Abstract:
The effects of restoration strategy and time on community structure and diversity were analyzed by investigating species composition, structure, and diversity of different restoration strategies and time communities. The results showed that restoration strategy had no effect on species composition and diversities of family, genera, species, tree, shrub, and liana, however, restoration time had significant effect on species composition and diversity. Species richness of family, genera, species, tree, and shrub decreased at the early stage and then increased with community succession. Species richness showed an inverse J-shape with DBH increasing in all community types, while abundance showed single peak curve with DBH increasing and an inverse J-shape with height increasing. The correlation and regression analysis among restoration strategies and times and variables of community structure and diversity showed that there were significant correlation between restoration time and variables of community structure and diversity, and no significant correlation were found between restoration strategy and most of variables of community structure and diversity, which indicated that restoration time was the major factor that affected the structure and diversity of community restored.
