【Abstract】 This article shows that use two methods to calculate the carrying capacity of animals on the grasslana in Qinghai province. These methods are the eatable grass and the animals neccessity for the nutrition of grass to compare, we have found the most appropriate carrying capacity of animals on the grassland in summer and autumn in this province is, 5909±709 ten thousand sheep units. (as 3200±383 ten thousanu mixed units). For the spring and winter grassland is : 3690±443 ten thousand units. (as 1998±240 ten thousand mixed units) In the past thirty years, the changes of amount of animal in Qinghai Province accorded with logist. What we have showed and the carrying capacity is still some distance, bur it is follow the animal ecology and the present condition of grassland in Qinghai Province.更多还原
