基于REC模型的污染场地修复决策支持系统的研究

摘要

REC模型在污染场地修复决策支持系统中应用广泛且较为成熟.该模型从风险降低(Risk reduction)、环境效益(Environmental merit)和修复费用(Cost)3个方面分析备选修复技术的综合效益,可以更客观地评估备选修复技术的优劣.阐述了污染场地修复决策支持系统的原理,详细介绍了REC模型评估方法,并采用该模型对某重金属污染场地的修复决策进行了实例应用,最后结合中国实际情况,提出了基于REC模型的污染场地修复决策支持系统的研发建议.%Extensive attention has been paid to contaminated site remediation all over the world. The REC model based decision support systems has widely applied in site remediation. The REC model decision on remediation alternative selection from 3 aspects of risk reduction,environmental merit and remediation cost,it could evaluate remediation technique more objectively. In this paper, basic theory of decision support system was elucidated firstly, and then the well designed and widely applied REC model was analyzed in detail. The application of REC was exemplified using a heavy metal contaminated site. At last, some proposals were given for decision support system development in China.
