摘　　要：为分析抚松县天然矿泉水水化学特征及形成机理,2017年采集天然矿泉水样品20组,综合运用Piper三线图、水化学类型分区图,分析抚松县天然矿泉水水化学特征;运用离子比值分析法、反向地球化学模拟分析矿泉水的形成机理。结果表明,抚松县天然矿泉水pH值为7.9~8.4,属弱碱性矿泉水,偏硅酸含量为33~53mg/L,属偏硅酸型矿泉水;天然矿泉水中Ca^2+、HCO3^-为优势离子;水化学类型主要有HCO3^-Ca型、HCO3^-Ca·Na型和HCO3^-Ca·Mg型。离子比值分析法和PHREEQC结果表明,该区水中主要离子受长石类、橄榄石、辉石的溶解-沉淀作用和阳离子交替吸附作用控制。In order to analyze the chemical characteristics and formation mechanism of natural mineral water in Fusong County,20 groups of natural mineral water samples were collected in 2017.The three-line diagram of Piper and the partition map of water chemistry types are used to analyze the hydrogeochemical characteristics of natural mineral water in Fusong County.The formation mechanism of mineral water was studied by ion ratio analysis method and reverse geochemical simulation method.The results show that the pH of natural mineral water in Fusong County is in the range of7.9 and 8.4,which belongs to weakly alkaline mineral water.The content of metasilicic acid is in the range of 33 and 53 mg/L,which belongs to metasilicic acid mineral water.Ca^2+and HCO3 are the dominant ions of natural mineral water;The types of water chemistry mainly include HCO3^-Ca,HCO3^-Ca·Na and HCO3^-Ca·Mg.The ion ratio analysis method and PHREEQC results indicate that the main ions in the water are controlled by cation alternate adsorption and the dissolution-precipitation of feldspar,olivine and pyroxene.
