Response of arid grassland community standing crop to banning grazing and deferral grazing management

摘要

Spring deferral grazing is a grazing strategy that can avoid grassland damage from livestock grazing and trampling during the sensitive grasses‐turning‐green period.The strategy can effectively improve grassland ecological environment (Li et al.,2001; Zhao et al.,2003; Li,2005).The study was conducted in two grazing systems of banning grazing and deferral grazing in Stip a breviflora desert steppe.Evaluations on the dynamics of forage yield were made for the two systems.The results may have important implication to the sustainable use of grassland and grassland ecosystem managements.
