Response of dominant species population importance value to different grazing systems in Stipa breviflora steppe

摘要：

The impact of grazing on the vegetation is an important field of grazing ecology.Most of that rational grazings can improve forage growth and livestock production.It can also improve grassland and prevent grassland degradation (Martin.SC 1988 ; Wei Zhijun et al,2003 ).Studied on dominant population importance value of desert grassland communities under different grazing system may explore reasonable grazing system and provide a theoretical basis for the sustainable use grassland resources.
