生物能源与粮食加工转化问题的研究

The research on bio-energy,grain processing and commercialization

中国人多地少,粮食安全至关重要。发展生物能源一定要在确保国家粮食安全基础上稳步推进。当粮食出现阶段性供过于求时,国家有计划地拿出一部分粮食加工转化为生物能源,将有助于平衡粮食供求,保护农民种粮积极性。首先分析了国内外发展生物能源的概况,从我国有限的耕地和农作物转化生物能源的合理性两方面分析了以粮食为原料加工转化为生物能源对粮食安全的影响,指出我国必须科学合理规划有限的可耕地,有效利用土地资源,并利用玉米和石油之间的线性关系说明了"粮食能源化"只能作为粮食供需平衡的"调节器"。

Grain security is very important because there are so many people are living on so little cultivated land in China. Bio-energy development must ensure the national grain security. It will help balance the supply and demand of grain and protect the peasant enthusiasm for cultivating grain if the country puts a part of grain into bio-energy when an over-supply of grain periodically comes up. The overview of the bio-energy development at home and abroad was analyzed at first. The effect that grain is processed and commercialized as raw materials into bio energy on grain security was also analyzed from the limited arable land and the rationality of conversion of bio-energy from crops. It was pointed out that our country must plan the limited arable land scientifically and rationally and utilize the land resources efficiently. It was also explained that the‘grain energy＇ could only be used as a ‘regulator＇ of grain supply-demand balance through the linear relationship between corn and petroleum.
