The effect of climate change on livestock carrying capacity of Inner Mongolia

摘要：

Since 1961 the annual temperature in Central and Eastern Inner Mongolia has increased by 0.9±0.2 ℃ with a 1.2 ℃ increase ℃ during winter ( December to February ) and spring ( March to May) (Figure1).Annual precipitation has varied markedly over this period with a decrease in the years since 1990.More than ten warm winter have happened since 1980 resulting in decreased mortality of old, weak and young animals resulting in an increased stocking rate in the following year with the potential for overgrazing.The combination of changing climate‐temperature increase, precipitation decrease, and the chang in precipitation pattern ‐together with increased stock numbers have accelerated grassland degeneration.
