| Abstract: | The present paper dwells on the types of grassland in Youyang County, Sichuan, their specific composition of plants, nutrient composition of the forage, forage yield and grazing capacity. The grassland in the county is of higy- class, average quality and higy yield, suitable for raising grass eating animals like goats. Theorectically,its grazing capacity amounts to 169,000 cow year,and the potential for improving its grazing capacity is great. Some suggestions for the rational utilization of the grassland are offered. |
