| Abstract: |
| 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. |
