Abstract:

Chinese traditional pastoral areas are short of water resources, have abundant grassland resource and insufficient fertility of soil, therefore grain crops are not suitable here. With the increase of resource constraints and explosive growth of animal products demand, grassland agricultures in the pastoral areas are imperative. The six main pastoral areas of China were studied to analyze the production status of traditional pastoral areas under current agriculture system; and to calculate the potential food productivity of grassland agriculture and to compare with the food production capacity of current agriculture system using the dimensions of food equivalent unit (FEU) and arable land rquivalent unit (ALEU). The results showed that the current agriculture systems of traditional pastoral areas were facing problems such as limited capacity of grain yield increase, high cost of production in animal husbandry and large proportion of forage grain, while the grassland agriculture mode could create 15142.4 thousand hm² more ALEU and 91772.8 thousand tons more FEU. According to these results, the necessity and advantages of developing grassland agriculture in traditional pastoral areas were discussed and some policy suggestions were put forward in order to develop grassland agriculture.
