Abstract: The Niyang river region is situated in the Linzhi prefecture of Tibet. The area of its farmland accounts for 64. 7% of the area of Linzhi. The development of planting industry has great influence on the local agricultural development. At present, the planting structure in the region is dominated by the cryophilic grain crops such as winter wheat,highland barley,etc. and the agro-climatic resources such as the temperature and precipitation in the three summer months have not yet been fully utilized. Considering the above fact and other reasons there is a need of a new strategy for the development of planting industry in the region.The theoretical analysis and partial practices have shown that developing corn as a high-quality feed grain is recommendable, because the development of corn can change the present monoculture structure of cool-season grain corps to a tribasic crop structure of grain. Cash crop and forage, including both cryophilic crops and thermophilic crops. As a result of the change in corp structure,it is easier to realize (1)the good combination of farming and animal husbandry, (2)the full and rational utilization of agroclimatic resources,and (3)speeding up the transformation of grain from food to feed and raising the transformation benefits.According to the thought mentioned above,the possibility,necessity,importance,developmental scale and strategic countermeasures of developing corn in the region are discussed fully in the paper.

Key words: the Niyang river region, corn planting, ecological adaptability.
