经分析论证，西藏粮食的结构性短缺和城镇居民对粮食的需求，靠“一江两河” 农业开发无法解决；种植业内部结构调整应逐渐压缩青稞面积，以满足该区藏民族的民食习 惯、游牧特点和青稞酒的原料需求为标准，增加小麦的种植面积；开发不等于开荒，本区开发 的重点是现有耕地，而不是开荒扩大耕地面积。 Through analysis and demonstration, the structural shortage of grain in Tibet and the demand for grain by urban residents can not be solved by the agricultural development of “one river and two rivers”. The adjustment of the internal structure of planting industry should gradually reduce the area of ​​barley in order to meet the needs of ethnic Tibetan people Habit, nomadic characteristics and raw material requirements of barley wine as the standard, increase the planting area of ​​wheat; development does not mean land reclamation, the focus of development in this area is the existing cultivated land, rather than land reclamation to expand the area of ​​cultivated land.
