摘要
简要介绍了生态足迹计算模型,论述了近年国际上争论的几个主要热点问题,数据的准确完整性,初级产品与二级产品,均衡因子与产量因子,全球产量与本地产量,以及能源足迹计算等,并对其进行了探讨和指出今后研究发展的方向。
This article introduces Ecological Footprint （EF） model briefly. It presents how the newest version of these accounts has become more consistent, reliable and detailed by using more comprehensive data sources, distinguishing more sharply between primary and secondary production, calculating and comparing factors and yields more consistently, and using methods to identify and eliminate potential errors in energy footprint. Then the heading of Ecological Footprint development has is pointed out.
