By using the method of space substituting time, alpine-cold steppe in different ages of enclosing was studied. We selected 4 flat plots with relatively uniform topography and enclosed time were 1-year old exclosure (E1), 3-year old exclosure(E3), 5-year old exclosure (E5), unexclosure. The grasslands were freely grazing pasture, grazing rate of 5.7 sheep / hm2. After enclosure, it was used as spring pasture, 5.7-grazing sheep / hm2. Unexclosure plot were 5.7-grazing sheep / hm2 in addition to the winter.
