摘　　要：分析了西藏一江两河地区农作物的生产效率优势、生产规模优势和综合比较优势。结果表明,拉萨市具有综合比较优势的农作物依次是小麦、油菜籽、蔬菜和青饲料,山南地区具有综合比较优势的农作物依次是小麦、青饲料、油菜籽、豆类,日喀则地区具有综合比较优势的农作物依次是豆类、青稞、蔬菜。除粮食作物外,其他作物空间布局尚未符合比较优势原则,但粮食种植比例偏高,作物间种植比例有待调整。提出未来几年种植业发展应该以提高粮食品质和生产效率为突破点,压缩发展粮食作物,适度发展经济作物,大力发展饲料作物。The efficiency advantage indicators, scale advantage indicators, and aggregate advantage indicators of crops in different areas are analyzed. The results show that the aggregate advantage crops are wheat, cole, vegetable and fodder in Lhasa, wheat, fodder, cole and bean in Lhoka, bean, highland barley and vegetable in Shigatse. The research also shows that only food crops＇ layout is according with the comparative advantage principle, so it is necessary to adjust the major planting structure, Then, some proposals for planting industry in the future are put forward, such as improving the quality of food production and productivity, decreasing the planting area of food crops, developing economic crops moderately, developing fodder crops vigorously.
