| 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。 |

| Abstract: |
| The theoretical livestock carrying-capacity of forage grasses in three-river regions in Tibet is 11.719 million sheep units,Total development potential of livestock 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. |
| Key words: forage grass,livestock-carrying capacity,development potential ,three rivers in Tibet |
