青海草地资源理论载畜量为1608．08×10^4羊单位。其中，天然草地载畜量为1282．84×10^4羊单位，人工草地载畜量为224．78×10^4羊单位，农作物秸秆载畜量为104．45×10^4羊单位，分别占理论载畜总量的79．77％、13．73％和6．50％。与全省2009年度存栏牲畜3020．05×10^4羊单位相比，超载1411．97×10^4羊单位，超载率87．81％，属重度超载，草地载畜压力指数为1．88。经畜、草平衡分析，青海牧区19个县共计需要减畜1183．26×10^4羊单位，减畜幅度为60．71％。

According to survey, the theoretic livestock carrying capacity of Qinghai grassland is 1608.08 ×10^4 sheep units, including 1282.84 ×10^4 sheep units of natural grassland, 224.78 ×10^4 sheep units of artificial grassland, and 104.45 ×10^4 sheep units of crop straw, accounting for 79.77% ,13.73% ,and 6.50% of total theoretic livestock capacity, respectively. Comparing with the actual livestock population （3020.05 ×10^4 sheep units） in 2009, there were 1411.97 ×10^4 overgrazing sheep units, with an overgrazing rate of 87.81% and grassland livestock carrying pressure index of 1.88, which suggests a state of severe overgrazing. Based on the carrying capacity and balance analysis result, the 19 pastoral counties of Qinghai should decrease their livestock population by 1183.26 ×10^4 sheep units, with a 60.71% of decrease rate.
