四川省甘孜藏族自治州位于青藏高原东南缘,平均海拔3500米。由于海拔高差、山川走向,气候上形成高山寒带、高山亚寒带、山地寒温带、山地凉温带、山地暖温带与河谷亚热带六个垂直气候带。而青稞则自河谷亚热带至小麦不能种植的高山亚寒带都有种植,常年播种面积50万亩左右。青稞面积为全州粮食作物播种面积的37.3%,总产占粮食作物总产的
Ganzi Tibetan Autonomous Prefecture in Sichuan Province is located in the southeastern margin of the Qinghai-Tibet Plateau, with an average elevation of 3,500 meters. Due to the elevation difference, the mountains and rivers move toward the climate and form six vertical climatic zones of alpine cold zone, alpine subtropical zone, mountain cold temperate zone, mountain cool temperate zone, mountain warm temperate zone and valley subtropical zone. The barley from the subtropical valley to the mountain can not be planted in alpine subtropical zone have planted perennial planting area of about 500000 acres. The area of barley is 37.3% of the sown area of grain crops in the state, with the total output accounting for the total output of food crops
