西藏“一江两河”农区草业发展探讨

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。
