Abstract
From investigation of grassland degradation area and grassland degradation degree in Xinghai county Qinghai province,the results showed that grassland degenerated obviously,degradation grassland area increased rapidly,it increased 108% during 5 years.Overstocking,pests and rodents are the main reason for becoming Heitutan.Put out to fund,control pests and rodents,adjust structure of live~stocking,set up high yield artificial grassland are the main measures to manage the Heitutan.
