| 摘 要： | 采用生态足迹方法对甘薯燃料乙醇循环产业各子系统（农业生产、乙醇生产、循环生产和废物处理4个子系统）的生态占用、资源循环利用和污染排放等情况进行了分析。结果表明,甘薯燃料乙醇循环产业链的延长伴随着生态足迹的增长,其中农业生产子系统生态足迹占用面积最大;生态足迹的经济效益随产业链的延长而增加,说明延长产业链可以提高资源利用效率;循环生产和废物处理子系统解决了乙醇生产过程中的环境污染问题;系统的能源生态足迹和水生态足迹较大,应重点降低能耗和水耗。

| Abstract: | The ecological footprint(EF)method was applied to analyze the EF,resources recycling and environmental pollution among various subsystems in the circulation system of pachyrhizus fuel ethanol,this system was made up of four subsystems which were the systems of agriculture,ethanol production,circulation production and waste treatment.The results indicated that the prolonging of production chain followed the increase of EF,in which the EF of agriculture occupied the biggest area.It was found that the increase... |
