摘　　要：西藏"一江两河"地区为适应未来西藏农牧业产品的优质、大量需求,必须大力发展农区草业。在一年两收农作制度中,采用饲草体系调控农业种植结构和"一江两河"的水热高效分配,既有利于该区农业结构调整,为畜牧业生产提供大量的优质牧草饲料;又有利于该区的生态环境保护,提高植被盖度和减小风速,控制水土流失。西藏"一江两河"农区草业的兴起,能减轻天然草地目前承受的巨大压力,减轻草地退化。发展饲草生产和畜产品深加工产业,使西藏成为高原特色畜产品生产基地,能加快当地农牧民的经济增长步伐。大力发展农区草业对促进西藏"一江两河"区域社会经济的发展,促进西藏地区可持续发展具有不可替代的重要意义。Grass-industry in agricultural area （three-rivers region） must be developed in Tibet so as to adapt to the Tibetan development in the future. In double cropping system of three-rivers area, the introduction of fodder production could adjust agricultural structure and water-heat pattern, and make the agricultural system more reasonable and environment conservation. Fodder production and grass growing could provide a lot of high quality forage for livestock production, and enhance vegetation coverage, reduce wind speed and soil loss. The development of grass-industry in agricultural area could alleviate the great livestock pressure in natural rangeland and slow down the grassland degradation. The development of fodder and livestock production industry could benefit the construction of special bases for livestock production, the economic development and then the income of herders. Therefore, grass system development in agricultural area was a key point to improving the sustainable development in three-rivers region.
