Spatial distribution of water consumption and deficit of main crops in Inner Mongolia Autonomous region, China

摘要

This paper focuses on five main crops in the Inner Mongolia Autonomous Region (Inner Mongolia): rice paddy (Oryza), wheat (Triticum aestivum), maize (Zea mays), millet (Setaria italica), and soybean (Glycine max). Water consumptions and deficits of five main crops in 2008 were analysed. By combining the effects of precipitation the results reflect that: (1) paddy should be cultivated mainly in southeastern areas of Inner Mongolia, and its total planting area should be properly reduced; (2) wheat is suitable to be cultivated in middle of Hulunbeier, Xingan League, Tongliao, Chifeng, east of Xilinguole League and Huhhot; (3) maize should be cultivated east of Hulunbeier; (4) millet should be cultivated in large areas in the west of Xilinguole League, north of Wulanchabu, Bayannaoer, Wuhai and Alashan League; and (5) soybean is adaptable to cultivation in the whole region, but Baotou and Erdos would be the priority.
