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

摘要：

Since 1949 annual temperatures have increased by 0.9±0.2℃ with 1.2±0.3℃ during winter ( December to February),1.2±0.2℃ during Spring (March to May) in central and eastern Inner Mongolia( Figure 1).Annual precipitation increased during the 1950s,decreased during the 1960s,increased during the 1970s,decreased during the 1980s,and decreased after the 1990s.More than ten warm winters have occurred since 1980 which benefited livestock compared with cold winters.Warm winters decreased the mortality of old,weak and young animal and increased herd sizes in following years.Large numbers of livestock lead to overgrazing and degeneration of the grassland.Temperature increases,precipitation decreases,and the changed of precipitation patterns,together with heavy stocking rates accelerated the process of grassland degeneration.
