摘要
中国农作物秸秆资源丰富,随着现代农业和现代加工技术的发展,通过农作物秸秆的多途径综合利用及转化增值,减少秸秆资源的浪费和环境污染,对节约稀缺的自然资源,替代耗竭性资源投入具有重大意义。分别从资源替代效应和直接环境效应宏观分析秸秆燃料、肥料、饲料利用的生态效应,在此基础上比较秸秆资源化利用的单项技术和综合技术、从生命周期考察技术的综合生态效应,强调技术的区域适应性,兼顾生态效益和经济效益。
China is abundant in its straw production and with the development of modern agriculture and advanced processing technologies it’s of great importance to the multi-path integrated utilization of straw resources for reducing the waste and environmental pollution especially for saving the scarce natural resources and substitution for depleted resources. This paper discusses the ecological effects of straws’ utilization as the fuels, fertilizer and feed in terms of resource substitution effects and direct environmental effects, based on which some conclusions and suggestions on technological selection can be arrived at by the comparison between single technology and integrated technology, integrated ecological effects applying life cycle analysis, emphasizing on regional accommodation to unify the ecological benefits and economic benefits.
