| 摘要: |
| 以某化学品泄漏造成大气污染为例，采用虚拟治理成本法，通过对污染物单位治理成本的调查，污染物危害系数的确定等步骤量化生态环境损害的数额。针对生态环境损害价值量化过程中主要污染物的选择、单位治理成本的确定、危害类别的判断等技术关键点，提出，应结合环境质量标准限值，污染物危害系数等综合因素选择主要污染物；采用成本函数法来确定某一地区单位治理成本更容易被采纳；利用标签制度（GHS）危险性类别的结论能够快速确定污染物危害系数，以期为大气环境损害鉴定评估技术方法的完善提供参考和借鉴。 |

| Abstract: |
| Take a chemicals leakage as an example, the virtual treatment cost method is used to obtain the quantitative amount of ecological environment damage through the investigation of the unit treatment cost of pollutants and the determination of the hazard coefficient of pollutants etc. In view of the technical key points such as the selection of main pollutants, the determination of unit treatment costs, and the judgment of hazard types in the process of quantifying the value of ecological environmental damage, some suggestions are put forward in order to provide reference for quantitative assessment of ecological and environmental damage: first, the main pollutants should be selected in combination with the comprehensive factors such as environmental quality standard limit and pollutant hazard coefficient; second, it is easier to adopt the cost function method to determine the unit governance cost in a certain region; third, using the conclusion of GHS risk category can quickly determine the hazard coefficient of pollutants. |
