利用生命周期评价法评价农作物秸秆人造板的环境特性

Value environment characters of crop stalks based board with life cycle assessment(LCA)

为了全面了解和评价农作物秸秆人造板的环境特性,利用生命周期评价法对农作物秸秆人造板全生命周期的环境特性进行了定性评价,并与木质人造板的环境特性进行了对比分析。结果表明,现阶段利用农作物秸秆生产人造板可有效地保护土地资源和林地资源,有利于固碳,减少二氧化碳的排放量。就农作物秸秆人造板生产线的建设、管理和经营提出了几点建议,使农作物秸秆人造板生产能够更适应人造板工业的发展需求。

The objective of the study was to know based board and valuing them qualitatively with environmental characters of the crop stalks with the and value the environmental the life cycle assessment characters of the crop stalks （LCA）, and compared the characters with the wood based board. The results show that it is benefits to protect soil resources, forestry resource, keep carbon and reduce the CO2 discharge. It also gives some suggestions about the building and managing of crop stalks based board production line in order to adapt better the development of wood-based board industry.
