The different measures of vegetation rehabilitation in subtropical degraded ecosystem, such as nature rehabilitation, semi-nature rehabilitation, and artificial rehabilitation, were compared, and the community comparison including species diversity, the niche, growth in diameter, volume of dominant trees, dry biomass of the communities and the soil nutrient substance were studied in this paper.

The paper analyzes the changes of soil in natural succession process including environmental features,nutrient and seed pool;furthermore it indicates climax community of Karst areas vegetation and specialty of direction towards community su.
