In order to increase the benefits and reduce the blindness of special-variety corn planting in the major planting area over the West Liaohe drainage area of the eastern Inner Mongolia, four special types of corns were selected as the research objects such as high-oil, high-amylum, high-lysine and sweet corns. Based on the needs of various corns for climatic conditions, soil types and topographic geomorphology, the planting regionalizing in- dexes of special-variety corn were presented with Tongliao as the demonstration area. By using of small-grid de- duction and GIS techniques, as well as the climatic similarity principle, the favorable planting areas for various special-variety corns were given respectively. It was pointed out that the most part of the agricultural area in Tongliao of Inner Mongolia is favorable for planting special-variety corns.
