Abstract: In order to assess the characteristics of forage yield structure in natural grassland of Gonghe County of Qinghai Province, the yield of economic groups of forage was calculated and investigated by correlation analysis. The results showed that the highest forage yield was observed in alpine meadow grassland and the dominant species were Cyperaceae plants; except for temperate grassland and lowland meadow grassland, the other natural grassland accounted for most of the yield of high quality forage, indicating that the degeneration degree of natural grassland in Gonghe County was generally slight and it could be restored by ecological engineering.
