摘要
该文依据2020 年8 月15~16 日高邮湖湖水及出入湖河水水质数据,采用Piper三线图、SPSS软件、Gibbs模型等手段,分析了高邮湖湖水与出入湖河水的水化学特征,揭示其主要离子来源及控制因素.结果表明,高邮湖湖水与出入湖河水整体为弱碱性淡水,优势离子均为Ca2+、Na+以及HCO3-;水化学类型湖水以HCO3-Na·Ca和HCO3-Na型为主,出入湖河水以HCO3-Na·Ca型为主;水化学特征受硅酸盐岩的风化溶解作用控制,且存在阳离子交换作用.该研究方法对于研究重点湖泊河流的水化学特征及形成机制具有一定的参考意义.
Abstract
Using methods such as Piper trilinear diagrams,SPSS software,and Gibbs model,this paper analyzes the hydrochemical characteristics of Gaoyou Lake water based on the lake water and water quality data from August 15-16,2020 of the inflow and outflow river water of Gaoyou Lake,and reveals their main ion sources and controlling factors.The results show that the inflow and outflow river water of Gaoy-ou Lake are generally weakly alkaline freshwater,with dominant ions being Ca2+,Na+and HCO3-.The hydrochemical types of lake water are mainly HCO3-Na·Ca and HCO3-Na,while the inflow and outflow river water is mainly HCO3-Na·Ca.The hydrochemical characteristics are controlled by the weathering and dissolution of silicate rocks,with the presence of cation exchange.The methodology of this study pro-vides a reference for researching the hydrochemical characteristics and formation mechanisms of key lakes and rivers.
