非粮生物质原料体系研发进展及方向

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。

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

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.
