摘　　要：本研究以长江经济带某典型化工园区为例,探索了该园区土壤与地下水污染的组成特征和分布情况。通过实地调查和采样分析,系统监测了该园区内外土壤与地下水的污染状况,并运用差异分析、相关性分析等,评估了污染物浓度水平的空间分布与组分特征;研究了多层次深度土壤与地下水污染物之间的相关性。结果表明,园区土壤污染物未超标,但Ni(p=0.018)、Cu(p=0.023)浓度显著高于园区周边,周边的Hg(p=0.074)高于内部;地下水污染物中1,2-二氯乙烷、Mn、Pb、二氯甲烷等多种指标超过国家标准,且部分点位超标程度较高,表明地下水受到了严重污染,同时园区地下水污染物与土壤多层次深度污染物整体相关性较低。本研究为该园区的风险评估和修复方案提供了科学依据,为长江经济带生态环境保护和可持续发展提供了科学支撑。This study takes a typical chemical industry park in the Yangtze River Economic Belt as an example to explore the distribution,risks,and management strategies of soil and groundwater pollution in the park.Through on-site investigation and sampling analysis,the pollution status of soil and groundwater inside and outside the park was systematically monitored,and the spatial distribution and composition characteristics of pollutant concentration levels were evaluated using differential analysis,correlation analysis,etc;The correlation between multi-level deep soil and groundwater pollutants was studied.The results showed that the soil pollutants in the park did not exceed the standard,but the concentrations of Ni(p=0.018)and Cu(p=0.023)were significantly higher than those around the park,and the Hg(p=0.074)around the park was higher than inside;Various indicators such as 1,2-dichloroethane,Mn,Pb,and dichloromethane in groundwater pollutants exceed national standards,and some points have a high degree of exceeding the standard,indicating that groundwater has been severely polluted.At the same time,the overall correlation between groundwater pollutants in the park and multi-level deep soil pollutants is low.This study provides a scientific basis for the environmental risk assessment and restoration plan design of the park,and provides scientific support for the ecological environment protection and sustainable development of the Yangtze River Economic Belt.
