| Abstract: | Natural regeneration ability of plant communities in different succession stages in Guizhou typical Karst area were studied by indexes reflecting the community regeneration characteristics,such as density of soil seed bank,density of seedling bank,density of seed trees,and other 2 key environmental factors which reflected the impact on changes of community regeneration bank as thickness of soil layer and community coverage in the sampling sites,to explore the regeneration ability and their influencing facto... |
