非粮生物质原料体系研发进展及方向

Progress and direction of non-food biomass feedstock supply research and development in China

非粮生物质原料供应是生物质能产业发展的最主要限制因素。本文系统分析了适合中国国情的非粮生物质和宜能非粮地概念,阐述粮食安全和生物质能源发展的关系,认为发展可持续非粮生物质能源是实现粮食、能源、生态、农村经济多赢的战略举措。进而,重点综述了当前中国非粮生物质原料及其供应体系研究进展,分析了当前迫切需要研发的重点任务,内容包括废弃物生物质资源及其可获得性,非粮能源植物种类筛选、育种和生产技术,原料生产、收获、收集和物流及其机械化,宜能非粮地的面积、分布和生产潜力,原料生产与供应的可持续性和标准化,供应产业模式及能源农业发展,发展规划和政策。

Non-food biomass feedstock supply is one of the most important limiting factors in fluencing biofuel development.In this article,the definitions of non-food biomass feedstock and non-food land for bioenergy crops are clarified according to the situation present in China.After identifying the relationship between food security and biomass energy development,it is shown that sustainable non-food biofuel will be a multi-win-win industry to improve food and energy production,eco-environment,and the rural economy and would not have negative effects on food security of the country.This article also reviews the progress of non-food biomass feedstock research,its supply system and further studies currently need in China.It includes the following areas：1）availability of residue biomass,2）nonfood bioenergy plant screening,breeding,and production technology,3）feedstock production,collection,and logistics and mechanization,4）distribution and potential of the non-food land for biomass production,5）sustainability and standardization of nonfood biomass feedstock production and supply,6）development of demonstration and bioenergy agriculture,and 7）planning and policy on the non-food biomass feedstock industry.
