摘要
以西藏阿里地区草地为研究对象,对草地资源概况、草地资源类型和草地载畜量等进行了分析。阿里地区草地理论载畜量为299.37万绵羊单位,2010年实际载畜量为346.66万绵羊单位,实际载畜量与理论载畜量相比超载15.80%。通过分析认为,阿里地区应因地制宜地发展草地畜牧业,合理布局草地载畜量,科学利用草地资源,促进草地畜牧业可持续发展。
In recent decades, the ecological environment of grassland in All of Tibet has degraded continu- ously, which has attracted attention of local governments at different levels. Therefore, it is urgent to probe into the causes and improvement techniques of the degradation. In this paper, the overview and types of grassland resources and grazing capacity in All of Tibet were discussed. The results showed that the theoretical grazing capacity of All region was 2. 993 7 million standard sheep and the actual grazing capacity is 3. 466 6 million in 2010. Compared with the theoretical grazing capacity, the actual grazing capacity overloaded 15. 80%. Based on the grassland resources and grazing capacity, it is suggested that the best suitable measures for local conditions should be taken, such as arranging grazing rationally and utilizing grassland resources scientifically to promote the sustainable development of animal husbandry.
