摘　　要：博尔塔拉河流域地质条件复杂,地表水与地下水转化频繁,研究地表水与地下水水化学特征及转化关系对流域水资源合理开发和配置具有重要意义.基于2021年4~5月采集的15组地表水样和39组地下水样,采用APCS/MLR模型和稳定氢氧同位素与水化学相结合的方法,分析了地表水和地下水水化学类型和氢氧同位素分布特征、水化学组分源贡献率和地表水与地下水转化关系.结果表明,地表水水化学类型主要为HCO_(3)·SO_(4)-Ca型和HCO_(3)-Ca型,地下水水化学类型主要为HCO_(3)·SO_(4)-Ca·Na型、HCO_(3)-Ca型和HCO_(3)·SO_(4)-Ca型;溶滤-迁移-富集因子、人类活动因子、环境因子和原生地质因子对地表水和地下水中离子的平均贡献率分别为28.8%、17.7%、12.0%和6.5%;博尔塔拉河河水中D和^(18)O沿程呈富集趋势,北岸地下水中D和^(18)O整体丰于南岸;在地质构造和水文地质条件等地质条件因素控制下,河水与地下水转化集中在博尔塔拉河中游,总体表现为河流两侧潜水和泉水溢出补给河水,补给比例范围为1.0%~70.9%.The geological conditions of the Bortala River basin are complex,and the transformation of surface water and groundwater is frequent.It is great significance to study the hydrochemical characteristics and transformation relationship of surface water and groundwater for the reasonable development and allocation of water resources in the basin.Based on 15 surface water samples and 39 groundwater samples collected in April and May 2021,the APCS/MLR model and the combination of stable hydrogen and oxygen isotopes with hydrochemistry were used in this study to analyze the hydrochemical types and the distribution characteristics of hydrogen and oxygen isotopes,the source contribution of chemical components,and the transformation relationship between surface water and groundwater.The results showed that the surface water was mainly HCO_(3)·SO_(4)-Ca type and HCO_(3)-Ca type,and the groundwater was mainly HCO_(3)·SO_(4)-Ca·Na type,HCO_(3)-Ca type,and HCO_(3)·SO_(4)-Ca type.The contribution rates of the dissolution-migration-enrichment factor,human activities factor,environment factor,and native geological factor to the chemical components were 28.8%,17.7%,12.0%,and 6.5%,respectively.Bortala River water D and ^(18)O was enriched along the distance,and groundwater D and ^(18)O in the north bank was generally more enriched than groundwater in the south bank as a whole.Under the control of geological conditions such as geological structure and hydrogeological conditions,the transformation of river water and groundwater was concentrated in the middle reaches of the Bortala River,which was generally manifested in both unconfined groundwater and spring overflow in the sides of the recharge river water,and the recharge proportion ranged from 1.0%to 70.9%.
