摘　　要：本文以安徽宿州埇桥区新濉河部分河段周边的20组浅层地下水样为研究对象,综合采用了描述性统计、Piper图法、Gibbs图法、相关性分析和主成分分析等方法,对该研究区内的浅层地下水水化学特征进行分析。研究结果表明:地下水水化学类型以 − Ca2 (Ca2 Mg2 )型和 Cl− − Ca2 (Ca2 Mg2 )型为主;地下水化学成分大部分受岩石风化作用影响,少数受蒸发作用影响;水岩作用与碳酸盐岩、硫酸盐岩、硅酸盐岩和岩盐的风化溶解作用有关。此外,人类活动也影响研究区浅层地下水水化学组分及特征。This study focused on 20 shallow groundwater samples of certain part of New Sui River, Suzhou City, and we conducted descriptive statistics, Piper plot, Gibbs plot, correlation analysis, and principal component analysis to analyze the hydrochemical characteristics. The results showed that the water types of shallow groundwater contained − Ca2 (Ca2 Mg2 ) and Cl− − Ca2 (Ca2 Mg2 ). The components of shallow groundwater were influenced by the rock weathering and a slight certain effect of evaporation. The water-rock interactions concluded the weathering and dissolution of carbonate rocks, sulfate rocks, silicate rocks, and rock salts. Additionally, human activities also affected the hydrochemical compositions and characteristics of shallow groundwater in the study area.
