内蒙古草原草原是中国最重要的奶牛、羊肉和羊绒产地。然而，集约化的放牧使草原草地严重退化。因此，复杂的放牧管理对于在经济上可行地利用草原而不扩大其荒漠化至关重要。本研究的目的是评估不同放牧管理制度和放牧强度（GI）对内蒙古草原放牧羊的活重增重（LWG）的影响，从而得出可持续草原利用的建议，同时考虑到农民对畜牧业生产的盈利利益和环境目标。短句来源2005-2009年6- 9月对6个不同GI值（>= 12、6-12、4.5-6、3-4.5、1.5-3和5-3）进行了为期5年的放牧试验
The Inner Mongolian grassland steppe is the most important grazing land in China in terms of cow milk, mutton, and cashmere production. However, intensive livestock grazing has severely degraded the steppe grassland. A sophisticated grazing management is therefore essential for an economically viable use of the grassland without amplifying its desertification. The objective of this study was to evaluate the effects of different grazing management systems and grazing intensities (GI) on liveweight gain (LWG) of sheep grazing the Inner Mongolian steppe in order to derive recommendations for a sustainable grassland use which considers both, farmers' interests of a profitable livestock production as well as environmental goals. A 5-year grazing experiment was conducted in June-September of 2005-2009 in which six different GI's (>= 12, 6-12, 4.5-6, 3-4.5, 1.5-3, and
