Grazing and drought interactively influence total plant density

摘要：

Great changes have taken place in vegetation in Inner Mongolian steppe due mainly to overgrazing in the past four decades.Overgrazing and N losses in combination with altered soil physical parameters and water availability further have been shown to exert strong impact on plant productivity, total density and height (Cingolani et al., 2005).In addition to grazing disturbance, drought also can significantly affect species height and density due to different drought resistant or tolerant ability.However, drought and grazing always interactively influence the ecosystem processes in grazing ecosystems.
