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.

Characteristics of vegetation with natural restoration in removal lands in loess hilly-gully region and the relationship between the characteristics and soil environment;

SOC change of natural restoration for black soil farmland;

The natural restoration of degraded rangeland ecosystem in Heshan hill land;

The variations of the light yield and the transmittance, the natural recovery and the heat annealling recovery of the radiation damage are measured.

This paper explored the reason and natural recovery of saline alkaline spots in Aneurolepidium chinense grassland.

In order to protect the ecology of Lake Honghu and study of aquatic vegetation restoration strategies, we have chosen a typical farming region to have the conventional survey of aquatic vegetation, water quality survey, zooplankton survey, seed bank survey, natural recovery test.

Objective:To prospectively study the relationships among spontaneous recovery, the lesion regions, and types of Chinese aphasia in patients after stroke.

The results showed that the spontaneous recovery of the patients were excellent in the two weeks post-stroke and were slowness in the later 6 weeks post-stroke.
