摘要

摘要:
以某搬迁电镀厂为例，根据污染场地调查报告内的采样数据，按照相关的污染场地污染标准筛选出污染的重金属类别，利用反距离权重法分析重金属在研究区的分布特征，运用莫兰指数进行空间关联分析，运用半变异函数分析重金属污染整体的空间结构和趋势，以探究污染场地的重金属污染空间特征。结果表明：研究区土壤中Ni、Cr、Zn、Cu浓度超过土壤背景值，其最高浓度采样点的风险标准限值倍数分别为9.55、1.35、5.94、10.67；Cu、Zn的浓度在场地范围内东西、南北方向上均呈倒U型趋势，中间高四周低；Ni、Cr浓度在空间分布特征较为相似，高值区域位于场地的东北边界处；4种超标重金属的空间特征差异较大，但均存在聚集特征。

Abstract:
Taking a relocated electroplating plant as an example and based on the sampling data in the survey report of the polluted site, the categories of polluting heavy metals were screened according to the Soil Environmental Quality-Risk Control Standard for Soil Contamination of Agricultural Land (Trial) (GB 15618-2018). The inverse distance weighting (IDW) method was used to analyze the distribution characteristics of heavy metals in the study area, Moran index was used for spatial correlation analysis, and the semivariogram was used to analyze the overall spatial structure and trend of heavy metal pollution, so as to explore the spatial characteristics of heavy metal pollution in the polluted site. The results showed that the concentrations of Ni, Cr, Zn and Cu in the soil in the study area exceeded the soil background value, and the risk screening value multiples of the sampling points with the highest concentration were 9.55, 1.35, 5.94 and 10.67, respectively. The concentrations of Cu and Zn showed an inverted U-shaped trend in the east-west and north-south directions within the site, high in the middle and low around. The spatial distribution characteristics of Ni and Cr concentrations are similar, and the high value area is located at the northeast boundary of the site. The spatial characteristics of the four over-standard heavy metals were quite different, but they all showed aggregation characteristics.
