生态足迹与印染

由于生态足迹概念比较具体、形象，其核算方法简便易行，目前对生态足迹的研究主要集中于水足迹及碳足迹的标准制定、模型建立及测算上。生态足迹分析法能改善资源的管理。纺织印染行业不仅是高耗水耗能行业，也是高废水废物排放行业，资源的有效利用率影响纺织印染行业的未来发展。以纺织品为研究对象，介绍了产品生态足迹的计算方法，包括水足迹的连锁求和法和步进式累积法和以PAS 2050：2008、ISO 14040：2006、ISO 14044：2006为参考标准来计算产品碳足迹的5个步骤。阐述了发展纺织印染行业生态足迹的意义。

Ecological footprint and printing and dyeing industry

Ecological footprint is a vivid and specific term with easy-applying accounting method, and the research of ecological footprint is focused on the standards developing, modeling and measuring of water footprint and carbon footprint. The analysis of ecological footprint is good for improving resource administration. The effective utilization rate of resources influences the development of printing and dyeing industry, because printing and finishing industry is a high water and energy consumption and high waste discharging industry. With textiles as research object, the calculation method of ecological footprint was introduced, including chain summation, stepping accumulation method and 5 steps for carbon footprint calculation based on PAS 2050：2008、ISO 14040：2006、ISO 14044：2006. The meaning of developing ecological footprint in textile printing and dyeing industry was expound.
