基于GIS的我国玉米秸秆纤维生产潜力研究

基于农作物生产潜力研究基础，利用GIS建立了我国玉米生产的空间数据库和属性数据库。通过对玉米生长期所需有效光和辐射进行光、温、水、土逐级修正后，计算得出玉米的生产潜力，根据一定的谷草比折算出玉米的秸秆生产潜力，以2006年我国各省玉米种植面积最终得出我国玉米秸秆纤维的潜力产量。我国玉米秸秆纤维生产潜力在2447.832-14079.55 kg•hm2之间，本研究为将来可用于生物燃料乙醇生产的纤维素资源的研究提供了基础。

Analysis of corn straw fibre Potential Productivity

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.
