| 中文摘要 |
| 为研究顺平县地下水化学特征及离子来源，服务顺平县水资源科学开发与管理，系统采集了县域33组岩溶水和12组孔隙水样品，综合利用Gibbs图、离子比值关系和多元统计分析方法，分析了顺平县各类型地下水水化学类型、组成特征和主要控制因素，评估各来源对地下水溶质的贡献率.结果表明，研究区孔隙水和岩溶水整体呈弱碱性，TDS变化范围分别为245.89~430.00mg ·L-1和223.54~1347.80mg ·L-1；阴阳离子组分以HCO3-和Ca2+为主.研究区内地下水聚类分为PW1、PW2类孔隙水和KW1、KW2、KW3类岩溶水，PW1和KW1类为HCO3-Ca ·Mg型水，PW2为HCO3 ·Cl-Ca ·Mg型水，KW2为HCO3 ·NO3-Ca ·Mg型水，KW3为高矿化度的SO4-Ca ·Mg型水.以白云石矿物为主的碳酸盐岩风化和以钠长石、钾长石为主的硅酸盐岩矿物风化是地下水主要的物质来源，对各水体的贡献均值分别为39.69%~66.13%和11.87%~58.38%；人类活动中生活污水排放和化肥使用分别对KW2类地下水和PW1、PW2、KW1类地下水存在显著影响，此外，大气降水对各水体的贡献率均值在1.09%~7.94%. |

| In order to study the chemical characteristics and ion source of groundwater and further serve the scientific development and management of water resources in Shunping County. A total of 33 groups of karst water and 12 groups of pore water samples were collected systematically in Shunping County, and the hydrochemical types, composition characteristics, and main controlling factors of various types of groundwater were analyzed by using Gibbs diagram, ion ratio relation, and multivariate statistical analysis methods, and the contribution rates of various sources to groundwater solutes were evaluated. The results showed that the pore water and karst water in the study area were weakly alkaline, with TDS ranging from 245.89 to 430.00 mg·L-1 and 223.54 to 1347.80 mg·L-1, respectively. The anion components of groundwater were mainly HCO3- and Ca2+. Groundwater in the study area could be grouped into PW1 and PW2 pore water and KW1, KW2, and KW3 karst water. PW1 and KW1 were HCO3-Ca·Mg type, PW2 was HCO3·Cl-Ca·Mg type, KW2 was HCO3·NO3-Ca·Mg type, and KW3 was SO4-Ca·Mg type with high salinity. The weathering of carbonate rock mainly composed of dolomite and silicate rock mainly composed of albiar and potassium feldspar were the main material sources of groundwater, and their contributions to each water body were 39.69% to 66.13% and 11.87% to 58.38%. Sewage discharge and fertilizer use in human activities had significant effects on KW2 groundwater and PW1, PW2, and KW1 groundwater, respectively. In addition, the contribution rate of atmospheric precipitation to each water body ranged from 1.09% to 7.94% on average. |
