In the pasture to perennial grass forages edge of grass, but the annual ZhuMao, such as soil and pointed YeLi height, coverage and density is larger, the grass and the important value of grass is bigger.

Under the influence of grazing in the lowest elevation, carried on the top, sandy meadow low wetland, the wetland of low diversity of the highest elevation GaoPingYuan grass minimum.

Grass of crude protein and crude fat content with the elevation of the decrease in altitude, the lowest value in the lowest elevation, crude fiber content decrease, calcium and phosphorus content was higher in medium elevations.

Soil mechanical components, sand and clay in the highest elevation of the highest levels of GaoPingYuan grass.

In the soil nutrient, soil nitrogen, phosphorus and nitrogen, rapidly-available potassium organic matter content in sandy meadow and low diversity of wetland soil phosphorus, the highest, rapidly-available phosphorus, total potassium content in sandy meadow and low wetland grass higher.
