国内外农作物秸秆供应模型研究进展

Research Progress of Corp Straw Supply Model at Home and Abroad

农作物秸秆是重要的生物质原料,其收集、存储存在诸多问题,秸秆无法稳定供应。为此,通过文献整理和实地调研,总结归纳了国内外农作物秸秆供应研究进展,对比分析了国外常用的IBSAL、SHAM及Bio Scope3种模型,并对国内外物流及成本相关研究进行归纳总结。针对我国秸秆供应还存在机械化程度低、物流模型不成熟、收集及运输费用高等诸多问题,建议提高机械化作业水平,尽快搭建适用于国内的秸秆供应模型,降低秸秆供应费用,为我国农作物秸秆综合利用提供原料供应保障。

Straws are important biomass feedstocks,due to the collection,storage,and many other problems,their supply system can't be steady. So this paper through literature review and field research,summarized research progress of straw supply model,comparatively analyzed three common foreign models-- IBSAL,SHAM and Bio Scope,and summarized studies associated with logistics and cost at home and abroad. In this paper,many problems are pointed out in our country's straw supply,such as low degree of mechanization,immaturity of logistics model,high cost of collection and transportation. We propose to improve the working level of the mechanization,set up straw supply model suitable for domestic as soon as possible and reduce the straw supply,to provide theoretical reference for crop straws supply model research in China.
