摘　　要：在收集213份20世纪80年代浅层地下水水质资料和616组现状采集样品的基础上,利用不同时期水化学组成在区域Piper三线图上的集合发生的位移现象,揭示20多年来该区浅层水的内在变化规律,同时利用水化学类型图、统计数据加以佐证,最后探讨区域浅层水演化的原因。研究结果表明,通过Piper图示所表达的浅层地下水水质演化规律统计数据、绘制水化学类型分布图等方法相比较,分析更简洁、直观、通俗易懂。通过分析还发现,区内浅层地下水资源可以通过合理利用而改善水质,进而为人们提供理想的水源。On basis of 213 phreatic water quality data in the eighties of last century and 616 samples＇ test results, this paper reveals the evolution of phreatic water in more than two decades by using the displacement in the district Piper diagram of water chemical composition in different periods, which is supported by maps of groundwater hydrochemical type and statistical data, and the reason of phreatic water evolution in this area is discussed. The results shows that the evolution of phreatic water expressed by Piper diagram is more concise, intuitive and user-friendly than that using statistical data and maps of groundwater hydrochemical type, and the quality of phreatic water can be artificially improved for providing ideal water source.
