Abstract: Based on crop potential production on the basis of using GIS to establish corn production of spatial database and attributes database. Through the corn growing period required for effective light and radiation light, temperature, water, soil amendments step by step, calculated corn potential production, according to a biomass energy convert coefficient then converted to corn potential production, Multiplied by the 2006 provinces in China Corn planting area reached the final potential outputof straw fiber.The corn straw fiber potential output in China were in 2447.832-14079.55 kg•hm2.This research can be used for bio-fuel ethanol production of cellulose resources for the study in future.
