摘　　要：安徽省常年主要农作物秸秆资源达3535万t,稻草、麦秸和油菜秸三者占3/4以上,其分布具有明显的区域性和各自特点。目前安徽省秸秆利用率仅为53.04%,还有近一半的秸秆未被利用,成为新的污染源。在现有的秸秆处理方式中,秸秆还田占28.2%,秸秆粗饲料占23.9%,秸秆资源化和工业原料化利用效率低。分析了安徽在现行技术、经济条件下应采取的秸秆利用策略,重点阐述了现阶段的综合利用可行途径,并设计了到2015年安徽省秸秆开发利用的发展目标。Staple crop straw yield was 35.35 million tons in Anhui Province every year. The straw of riee, wheat and rape were principal and their proportion in total was above 75%. Their distributions have obvious regional and individual characteristics. Their utilization rate in Anhui Province is only 53.04% currently, and nearly half of them have not being used, that have become a new source of pollution. Among the existing ways of straw utilization, retur- ning back to the fields and being fodder were 28.2% and 23.9%, respectively. But the utilization efficiency of taking straw as resources and industrial raw materials were very low. This article analyzes the strategy of straw utiliza- tion under the existing technological and economical conditions, puts forward feasible approaches for integrated utili- zation of crop straw, and designs the goals for developing and utilizing crop straw in Anhui Province till 2015.
