Effect of Different Grazing Intensity against the Features of Grassland Vegetation Community
The paper studies the changes of coverage, height, density and biomasse of grassland vegetation under different levels of grazing intensity by measuring the four levels of grazing, that is, light grazing(BA1), medium grazing (BA2), heavy grazing (BA3) and comparison in Chunqiu Meadow of Beishan Tieliekti. It is found that the main dominant species of grassland vegetation community is grassland sedge, chiba yarrow, clover and kentucky bluegrass, and different levels of grazing intensity can bring certain effects to phytocoenosium, especially, the coverage, density and biomasse of grassland vegetation tends to decrease as the grazing intensity is increasing.
