摘要 西藏“一江两河”地区饲草理论载畜量为1171.9万羊单位,开发潜力为480.9万羊单位,其中天然草地已无潜力可挖,且已超载9.17万羊单位,今后饲草开发的重点为改进作物秸秆加工利用技术,提高利用率,并扩大加强人工草地建设。 The theoretical livestock carrying-capacity of forage grasses in three-riv-er regions in Tibet is 11.719 million sheep units,Total development potential of live-stock carrying-capacity of forage grass resources is 4.809 sheep units ,of which there isno potential for natural grassland to be developed.and there is already over stocking of91700 sheep units. As a result,the furture development priority should be to improve thepresent processing technique of crop straws and raise their use efficiency and expand theconstruction of artificial grassland.
