A test of grazing experimental design and grazing effects in a mixed grassland ecosystem

摘要：

Most of grazing experimental designs are based on an assumption that the grassland condition of experimental areas are similar before the grazing experiments carried out.Therefore,any changes between different grazing intensities are contributed to grazing effects.Sparse researches test the assumption due to difficulty in finding a large,no grazing disturbance and natural grassland area.The grazing induced changes are difficult to clarify with these grazing experiment designs.Hence,it is important to validate the grazing experiment design before the experiment carried out,and assess the grazing impact based on a proper experiment design.
