| 以安徽省某废弃钢铁厂为例，分别使用GMS软件和反距离权重插值法（IDW）构建相应的地下水数学模型，开展研究区土壤修复工程对地下水流场的扰动影响及区域污染物空间变化特征的研究。结果表明：在工程施工完毕初期，研究区阻隔墙2右侧的基坑降水使得周边地下水位出现了一定程度的降低，阻隔墙上游地下水位出现0m～025m的壅高，下游地下水位出现0m～040m的下降；工程完成半年后，工程施工对地下水流场的影响逐渐减小，地下水流向没有发生明显改变；土壤修复后地下水中Fe、Cu、Pb和As含量明显降低，污染物空间分布也发生了相应的变化。 |

| Taking an abandoned steel plant in Anhui as an example， the corresponding groundwater mathematical models were constructed by GMS software and inverse distance weight（IDW） interpolation method， respectively， and the disturbance effect of soil remediation project on groundwater flow field and the spatial change characteristics of regional pollutants in the research area were studied. Results showed that in the early stage of the completion of the project， the precipitation in the foundation pit on the right side of barrier wall No.2 caused a certain degree of decrease in the surrounding groundwater level. The groundwater level increased by 0 m~0.25 m in the upstream of the barrier wall， and decreased by 0 m~040 m in the downstream. Half a year after the completion of the project， the impact of the construction on groundwater flow field gradually decreased， and the direction of groundwater flow did not change significantly. After soil remediation， the contents of Fe， Cu， Pb and As in the study area decreased significantly. The spatial distribution of the pollutants also changed 〖GK!86mm〗accordingly. |
