摘　　要：目的:探究富阳区域土壤潜在污染的主要影响因子。方法:以区域内主要工业区为研究对象,采集土壤和地下水样品,并进行土壤污染和地下水流场检测。基于地下水流场,采用特征选择算法模拟区域土壤的潜在污染情况,选取土壤潜在污染影响因子并计算贡献率。结果:在选取的潜在污染影响因子中,地下水pH值、土壤含水率和土壤黏粒含量对土壤潜在污染的贡献率最高,分别达到0.155、0.083、0.076。结论:在该区域中,地下水pH值、土壤含水率和土壤黏粒含量为主要的土壤潜在污染影响因子,因此在进行土壤环境改善和土地再利用时应考虑这些因素的影响。Purpose:To explore the main influencing factors of potential soil pollution in the Fuyang region.Method:Taking the main industrial areas in the region as the research object,soil and groundwater samples were collected,and soil pollution and groundwater flow field were detected.Based on the groundwater flow field,a feature selection algorithm is used to simulate the potential pollution situation of the soil in the region,select potential soil pollution influencing factors,and calculate their contribution rates.Result:Among the selected potential pollution influencing factors,groundwater pH value,soil moisture content,and soil clay content have the highest contribution rates to soil potential pollution,reaching 0.155,0.083,and 0.076,respectively.Conclusion:In this area,groundwater pH value,soil moisture content,and soil clay content are the main potential soil pollution influencing factors.Therefore,the impact of these factors should be considered when improving soil environment and land reuse.
