摘要
选取某无机氟化物和重金属钒场地内2m×2m大小的正方形为研究区域,于区域内布设6个土壤采样点位,采集不同深度土壤样品,分析土壤氟化物和钒的含量,初步探讨污染物在研究区域的空间变异及其对污染场地调查的影响。研究结果表明,土壤氟化物和重金属钒在水平与垂直方向呈现出不同的空间变异,导致场地的评价结果具有不确定性,随着采样点位增加,不确定性降低。
A 4m2(2m×2m)rectangle site has been selected as the study area, which contains inorganic fluoride and heavy metal vanadium. Six sampling points has been set in the range. The soil samples are sampled from different depths and all of them are selected to analyzing soil fluoride and vanadium. The study has a preliminary discussion on the effects of spatial variability of pollutants in the study area and spatial variability of pollutants on the investigation of contaminated sites. The results shows that soil fluoride and heavy metal vanadium exhibit different spatial variability in horizontal and vertical directions, which leads to uncertainty in the evaluation results. As the sampling point increases, the uncertainty of evaluation decreases.
