环境足迹是近年来国际生态经济学的研究热点。从指标的分类与整合两方面对环境足迹进行了深入分析。基于所涉及的资源代谢方式,将环境足迹分为资源足迹、排放足迹和复合足迹三大类;基于足迹内部各组分之间的加和方式,又进一步将其分为等权加和与特征化加和两类。据此提出了两种环境足迹整合范式:一种基于系统资源代谢,对所有物质流量进行等权加和,从而公式化表达资源总足迹、排放总足迹和环境总足迹;另一种基于生命周期影响评价,通过特征化加和清单物质来量化各类环境足迹,然后对核算结果进行标准化和权重化处理,最终得到环境影响综合评价指数。
環境足跡是近年來國際生態經濟學的研究熱點。從指標的分類與整閤兩方麵對環境足跡進行瞭深入分析。基于所涉及的資源代謝方式,將環境足跡分為資源足跡、排放足跡和複閤足跡三大類;基于足跡內部各組分之間的加和方式,又進一步將其分為等權加和與特徵化加和兩類。據此提齣瞭兩種環境足跡整閤範式:一種基于繫統資源代謝,對所有物質流量進行等權加和,從而公式化錶達資源總足跡、排放總足跡和環境總足跡;另一種基于生命週期影響評價,通過特徵化加和清單物質來量化各類環境足跡,然後對覈算結果進行標準化和權重化處理,最終得到環境影響綜閤評價指數。

Footprint is one of the research topics which have grown in popularity in the field of ecological economics. By investigating the classification of environmental footprints, we got three broad categories: resource footprints, emission footprints and composite footprints. According to two existing schemes for the aggregation of different components of each footprint, in principle all of the footprints can be further classified into equally-weighted aggregation and characterization- based aggregation. Hereby, we present two paradigms for the integration of environmental footprints. One is to formulate the total resource, emission and environmental footprints by summing all the material flows in relation to the system's resource metabolism with equal weights. The other is to characterize, normalize and weigh the inventory flows within life cycle impact assessment to yield an integrated environmental footprint index which is dimensionless and comparable.
