氮足迹模型应用进展研究

氮足迹是一个评估人类活动活性氮排放量的指标,能够定量人类生产、生活各个环节的活性氮排放,进而指导个人消费和食品生产方式的转变,最终达到降低活性氮排放和提高环境质量的目的.氮足迹模型是定量不同实体氮足迹关键,也是当前氮足迹研究的热点所在.本文综述了应用于个人、食品、机构、事件的氮足迹模型;探讨了氮足迹的不确定性以及优化措施;流域氮足迹,产品氮足迹以及建立生态足迹数据库等将成为未来的研究热点.

Advance in Application of Nitrogen Footprint Model

Nitrogen footprint is the index of active nitrogen discharge, which could quantify active nitrogen discharge in hu-man production and daily life.It can guide the change of personal consumption and food production.Then it ultimately achieves the goal of lowering active nitrogen discharge and improving the quality of environment .Nitrogen footprint model is the key to quantify nitrogen footprint of different entities and also is hot spot research about current nitrogen footprint .This paper summarizes nitrogen footprint models applying to person, food, institution and event;discusses uncertain of nitrogen footprint and optimization measures;puts forward future hot spot research such as basin nitrogen footprint, product nitrogen footprint and establishment of zo-ology footprint.
