中文摘要:
      针对农用地土壤环境损害鉴定评估缺乏统一规范、科学合理、操作性强的技术标准等问题,从外部因素、时间属性、内在状态等方面诠释了土壤基线水平的内涵特征;从来源、构成等方面构建了农用地土壤基线水平指标体系;从资料收集、现场调查、监测采样、专家咨询等途径分析了农用地土壤基线水平信息的获取方法;从基于时间参比的背景值或本底值、基于空间参比的对照值、基于统一尺度的标准值或基准值、基于生态风险的剂量/强度-效应值和基于头脑风暴的专家判定值等方面比较了5种农用地土壤基线水平值的特点和适用情形,并提出了农用地基线水平优先顺序的确定程序与方法,最后对未来土壤基线水平研究提出了展望。
英文摘要:
      This study aimed to solve the problems, such as the absence of uniform norms as well as scientific operational technical standards, for the identification and assessment of soil environmental damage on agricultural land. The connotative characteristics of soil baseline level were interpreted based on external factors, temporal attributes, and internal state. The indicator system of the soil baseline level of agricultural land was constructed using the source and composition. We analyzed data collection, field investigation, monitoring and sampling, and expert consultation to determine the best method for obtaining information on the soil baseline level in agricultural land. The characteristics and applicability of the five types of agricultural land soil baseline levels were compared in terms of background or backdrop value based on temporal reference, control value based on spatial reference, standard or baseline value based on uniform scale, dose / intensity-effect value based on ecological risk, and expert judgement value based on brainstorming. Then, the procedure and method for determining the priority of the baseline levels for agricultural land were proposed. Finally, a prospect for future research on soil baseline levels was suggested.
