企业土壤环境风险管理水平分级评价方法研究

Research on the Hierarchical Evaluation Method of Enterprise Soil Environmental Risk Management Level

为了更好地监督和管理企业完成土壤和地下水污染隐患排查整改工作,提出一种量化的方法来评估土壤和地下水污染隐患排查结果,在此基础上运用层次分析法和灵敏度分析法对企业土壤环境风险管理水平的评价指标进行筛选和权重计算,构建了企业土壤环境风险管理水平的分级评价方法,将其分为高、中、低三个级别,并运用构建的评价方法对五个典型的重点监管单位企业的土壤环境风险管理水平进行了评价和验证。结果显示,该评价方法考虑了有毒有害物质的环境风险,是合理可靠的,可适用于不同类型企业的土壤和地下水污染隐患排查的分级分类管理。

In order to better supervise and manage the investigation and rectification of soil and groundwater pollution hazards in enterprises,a quantitative method was proposed to evaluate the results of the investigation of soil and groundwater pollution hazards.The Analytic Hierarchy Process(AHP)and Sensitivity Analysis Method were applied to select and calculate the evaluation indicators and weights for the level of soil environmental risk management in enterprises.A hierarchical evaluation method for the level of soil environmental risk management in enterprises was constructed,dividing it into three levels:high,medium,and low.The constructed evaluation method was then used to evaluate and validate the level of soil environmental risk management in five typical key regulatory enterprises.The results showed that this evaluation method considered the environmental risks of toxic and harmful substances,and it can be applied to the hierarchical classification management of soil and groundwater pollution hazards in different types of enterprises.This indicated that the constructed evaluation method was reasonable and reliable.
