| 中文摘要 |
| 新疆托克逊县绿洲区由独立的托克逊绿洲区和库米什绿洲区组成,地下水作为当地居民生产生活的重要水源,探明地下水水质优劣及污染源,对地下水资源可持续开发利用、生态环境保护及人类健康具有重要意义. 于2023年7月在该区采集9组潜水样和12组承压水样并测定主要水化学特征指标,综合运用数理统计分析、Piper三线图、Gibbs图、离子比值和主成分分析等方法研究和探讨了不同区域地下水水质控制因素及污染源,利用水质指数（WQI）法评价了地下水水质,并运用综合健康风险评价模型对地下水NO3-的潜在风险进行了评估. 结果表明,研究区内地下水整体呈碱性,水化学类型复杂多样,托克逊绿洲区以Cl·SO4·HCO3-Na·Ca型为主,库米什绿洲区水化学类型主要为Cl·SO4-Na·Ca型；托克逊绿洲区整体水质较好,水质以Ⅰ和Ⅱ类水为主（91.7%）,库米什绿洲区水质整体较差,水质以Ⅳ和Ⅴ类水为主（77.8%）；健康风险评价表明托克逊绿洲区婴儿和青少年存在较高的健康风险；库米什绿洲区婴儿、儿童、青少年和成人均有较高的健康风险,且婴儿对其非致癌健康风险更敏感；源解析结果表明,研究区地下水不同含水层具有相似的来源或者演化过程,溶滤-富集作用（F1,贡献率为66.1%）、人类活动（F2,贡献率为15.8%）和原生地质（F3,贡献率为8.0%）是影响研究区地下水水质演化过程的主要因素. |
| 英文摘要 |
| The groundwater of the oasis areas of Toksun County, Xinjiang, including the Toksun and Kumishi oasis areas, is an important source of water for the production and daily life activities of local people. The sustainable development and utilization of groundwater resources, ecological environment protection, and maintenance of human health are crucial factors to determine the quality and pollution sources of groundwater. In July 2023, nine groups of unconfined and 12 groups of confined groundwater samples were collected from the oasis area. The main water chemical characteristic indicators were measured, and the control factors and pollution sources of groundwater in different regions were studied and discussed by the comprehensive use of mathematical statistics analyses, Piper three-plot, Gibbs chart, ion ratio, and principal component analysis. The groundwater quality was evaluated using the water quality index （WQI） method. The potential risk of NO3- in groundwater was evaluated by a comprehensive health risk assessment model. The results showed that the groundwater in the study area was alkaline, and the hydrochemical types were complex and diverse. The water chemical type in the Toksun oasis area mainly comprised Cl·SO4·HCO3-Na·Ca, whereas that in the Kumishi oasis area comprised Cl·SO4-Na·Ca. The overall water quality in the Toksun oasis area was good, and mainly involved Class I and II water （91.7%）. The water quality in the oasis area of Kumishi was poor, and mainly involved Class IV and V water （77.8%）. The health risk assessment showed that infants and adolescents faced higher health risk in the Toksun oasis area. Infants, children, adolescents, and adults in the Kumishi oasis area faced higher health risks, with children being more sensitive to the risk of cancer caused by inorganic substances in groundwater. Source analysis results showed that groundwater of different aquifers in the study area had similar sources or evolution processes, and leaching-enrichment （F1, contribution rate of 66.1%）, human activity （F2, contribution rate of 15.8%）, and original geological conditions （F3, contribution rate of 8.0%） were the main factors affecting the evolution of groundwater quality in the study area. |
