摘　　要：探索区域尺度污染场地环境足迹评估国内研究较少且具有重要意义。以京津冀某中心城市区域为研究对象,在界定评估边界和构建数据清单的基础上,采用国际上广泛应用的环境足迹分析计算工具SEFA,进行环境足迹的定量评价。评估结果表明,区域内8个亟待开发的污染场地修复活动的场内材料和药剂总消耗量1.8×10^(4)t,场外废弃物总处置量1.2×10^(5) t,总用水量3.3×10^(4)m^(3),总能源消耗量1.4×10^(9)MJ,NOX、SOX和PM总排放量68.5 t,有害空气污染物总排放量0.7 t,温室气体总排放量1.1×10^(4)tCO_(2)e,温室气体排放强度140.1 kgCO_(2)e·m^(-3),修复活动的材料和药剂使用环节温室气体排放量贡献率高达84%。研究结果为区域多污染场地绿色可持续修复提供重要参考。Assessing the environmental footprint of contaminated sites on a regional scale is a relatively underexplored yet crucial area in environmental studies.This study focuses on a central city in the Beijing-Tianjin-Hebei region.Based on the definition of evaluation boundaries and the development of a data inventory,we utilized the widely recognized environmental footprint analysis tool,SEFA,to conduct a quantitative assessment.The results show that the remediation activities at eight priority polluted sites led to a total consumption of 1.8×10^(4)tons of materials and reagents,while the total waste disposal was 1.2×10^(5) tons.The total water usage reached 3.3×10^(4)m^(3),and total energy consumption amounted to 1.4×10^(9)MJ.The total emissions of NOX,SOX,and PM were 68.5 tons,with hazardous air pollutant emissions totaling 0.7 tons and greenhouse gas(GHG)emissions amounting to 1.1×10^(4)tCO_(2)e.The GHG emission intensity was 140.1 kgCO_(2)e·m^(-3),with 84%of the GHG emissions arising from the material and reagent usage phase.These findings provide valuable insights for the green and sustainable remediation of multiple polluted sites in the region.
