土壤生态环境损害鉴定评估中基线确定方法讨论

随着近年来我国经济的高速发展,各地生态环境污染和破坏形势日益严重,特别是涉及土壤环境的污染和破坏事件日益增加,需要对发生土壤污染的场地进行损害鉴定评估工作。根据生态环境部《生态环境损害鉴定评估技术指南总纲和关键环节第1部分:总纲》(GB/T39791.1-2020)等技术规范,规定了4种基线确定方法:即历史数据法、对照数据法、标准基准和专项研究等方法。通过相关案例,主要分析了土壤生态环境损害鉴定评估工作中对照数据法中基线值确定方法,为后续开展相关土壤环境损害鉴定评估工作提供一定的参考。

Discussion on Determination of Baseline in Assessment of Soil Eco-Environmental Damage

With the rapid development of China’s economy in recent years,the pollution and destruction of ecological environment are becoming more and more serious,especially the pollution and destruction of soil environment.In order to meet the increasing attention of the department in charge of ecological environment and the public to the soil pollution,it is necessary to assess the damage of the contaminated sites.Baseline determination is a key step in determining whether damage has occurred at a contaminated site.According to the Technical Guidelines for Assessment of Ecological Environmental Damage-Part 1:General Guidelines(GB/T39791.1-2020)and other technical specifications,four methods of baseline determination,namely,historical data method,contrast data method,standard benchmark and special research method are provided.In this paper,the method to determine the baseline value of the control data method in the assessment of soil eco-environmental damage is analyzed through the relevant cases,which can provide some reference for the follow-up assessment of soil eco-environmental damage.
