Effect of grazing gradients on soil microbe variation in Inner Mongolia steppe

摘要

Soil microbes are very important parts in grassland ecosystem.It forms a powerful dynamical resources store and plays a key role in plant residues decomposition, humus formation and nutrients transition and cycle.Numerous studies have suggested that grazing by livestock will influence soil physical and chemical qualities on grassland while soil microbe will promote nutrients transition under reasonable grazing density.we detected the variation of soil microbes.
