摘要/Abstract

摘要： 在综合分析地质条件基础上，运用水化学及同位素技术，并结合现场调查及室内分析的方法，对霍景涅里辛沙漠地下水进行研究，分析了研究区地下水化学及稳定同位素特征，讨论了地下水的矿化过程及影响因素，确定了沙漠区地下水的补给来源。结果表明：沙漠区潜水中各离子组分平均值均大于承压水，潜水的溶解性总固体（TDS）平均值远大于承压水，说明潜水的蒸发作用大于承压水；控制潜水中主要离子成分的作用主要为溶解作用、交替吸附作用以及蒸发作用，控制承压水中主要离子成分的作用主要为溶解作用；沙漠区潜水与承压水具有一定的水力联系；地下水的补给来源主要为山区冰雪融水及降水，潜水的补给高程为1 370m，承压水的补给高程为1 650m。

Abstract: Based on comprehensive analysis of geological and hydrogeological conditions, using the hydrochemical and isotope technique, and combined with the method of field investigation and office analysis, study on groundwater in Hopenne Lee Sin Desert. Groundwater chemical and stable isotope characteristics in the study area are analyzed and discussed the mineralization process and influence factors of groundwater, determine the desert area of groundwater recharge source. The hydrochemistry results showed that the mean values of each component in the phreatic water were higher than that of confined water, phreatic water is greater than the TDS of average confined water, phreatic water evaporation is greater than the confined water. Through the analysis of ions in groundwater in the study area and gibbs diagram, illustrate that the main ion components in the control of phreatic water are dissolution, adsorption and evaporation, the main ion components in the control of confined water are dissolution. Stable isotope results show that the phreatic water and confined water has a certain hydraulic connection. Groundwater recharge sources of major ice and snow melt water and precipitation in the mountain areas, phreatic water recharge altitude of 1 370 m, confined water recharge altitude of 1 650 m.
