摘　　要：以位于中国新疆地区的叶尔羌河流域为例,在概述流域地下水运移概况的基础上,分三次进行了样品的采集和测定,并依托测定结果,采用Piper三线图法、舒卡列夫分类法展开典型区地下水水化学特征分析。结果表明,叶尔羌河流域典型区水化学类型及成因较为复杂,且由西向东表现出明显的分带性特征,西部山区(即Ⅰ区)水化学类型以重碳酸钙、碳酸硫酸钙为主,为淡水区;东部平原区(即Ⅱ区)水化学类型则以碳酸钠镁和硫酸钠镁型为主,为咸水区。地下水中TDS含量与各离子相关性的分析为流域地下水资源的开发利用提供了思路。Taking the Yarkand River Basin in Xinjiang region of China as an example,on the basis of an overview of groundwater movement in the basin,samples are collected and determined in three stages.Based on the measured results,Piper method and Shukarev classification method were used to analyze the chemical characteristics of groundwater in typical areas.The results showed that the types and causes of hydrochemistry in typical areas of the Yarkand River River basin are complex.It showed obvious zonation from west to east.The main hydrochemical types were calcium bicarbonate and calcium bicarbonate sulfate in the western mountainous area(Area Ⅰ).The main hydrochemical types were sodium magnesium bicarbonate and sodium magnesium sulfate in the eastern plain area(Area Ⅱ).The main hydrochemical types were calcium bicarbonate and calcium bicarbonate sulfate in the western mountainous area(Area I),and sodium magnesium sulfate in the eastern plain area(Area II).The analysis of the correlation between TDS content and ions in groundwater provided a new idea for the development and utilization of groundwater resources in the basin.
