| 中文摘要 |
| 车尔臣河流域气候干旱少雨,水资源相对匮乏,查明流域河水与地下水化学特征及高硼来源,对水资源的可持续开发利用、保护动植物及人体健康具有重要意义.为初步探明车尔臣河流域水化学特征及硼（B）的主要来源,2023年共采集了46组水样（其中6组河水、40组机井水）,运用Piper三线图、Gibbs图,相关性分析、水文地球化学模拟、绝对主成分分析（PCA-APCS-MLR）等方法对车尔臣河流域河水与地下水的水化学特征及其B的来源进行初步分析,定量评估了不同因子对水中B和其它水化学组分的贡献.结果表明,车尔臣河流域河水与地下水整体呈弱碱性,pH均值为7.99,地下水主要为微咸水及咸水,阴阳离子主要以Cl-、Na+为主.水化学类型较多,其中河水以SO4·Cl-Na型和HCO3·SO4·Cl-Na型为主；地下水以SO4·Cl-Na型为主.区内河水中ρ（B）均值为1.80 mg·L-1,超标率为66.7%；地下水中ρ（B）均值为1.48 mg·L-1,超标率为45.0%. APCS-MLR受体模型分析揭示了水化学组分及B的来源主要有溶滤-富集因子、人类活动因子、原生地质因子和未知源.车尔臣河流域水中硼超标现象明显,原因主要为农业活动（肥料与杀虫剂）及未知源,同位素技术有望更进一步探明水中B的主要来源. |
| 英文摘要 |
| The climate of the Cherchen River Basin （CRB） is dry and rainless and the water resources are relatively scarce. Identifying the chemical characteristics and high boron sources of surface water and groundwater in the basin is important for the sustainable development and utilization of water resources and the protection of animals, plants, and human health. To preliminarily explore the chemical characteristics and the main sources of boron （B） in the CRB, a total of 46 groups of water samples （including six groups of river water and 40 groups of well water） were collected in 2023. The chemical characteristics of surface water and groundwater and the sources of boron in the CRB were preliminarily analyzed using a Piper diagram, Gibbs chart, correlation analysis, hydrogeochemical simulation, and absolute principal component analysis （PCA-APCS-MLR） and the contribution of different factors to boron and other chemical components was quantitatively evaluated. The results showed that the water resources in the CRB were weakly alkaline, with an average pH of 7.99. The groundwater was mostly brackish water and salt water and the anions and cations were mainly Cl- and Na+. Many types of water chemistry were present, among which the river water was mainly SO4·Cl-Na type and HCO3·SO4·Cl-Na type. The groundwater was mainly SO4·Cl-Na type. The average content of boron in river water in the area was 1.80 mg·L-1 and the over standard rate was 66.7%. The average content of boron in groundwater was 1.48 mg·L-1 and the exceeding standard rate was 45.0%. APCS-MLR receptor model analysis further revealed that the major sources of water chemical components and boron were leaching-enrichment, anthropogenic activity, and primary geological factors and unknown sources. The phenomenon of boron exceeding the standard in the water of the Cherchen River Basin was obvious, mainly due to agricultural activities （fertilizers and pesticides） and unknown sources. Isotope technology may further identify the main sources of boron in water. |
