摘要
为查明新泰市地下水水化学特征及其离子来源,分别于2017年9月和2018年5月各采集29件地下水水样,综合运用数理统计、相关性分析、Piper三线图、Gibbs图以及离子比等方法对水样测试结果进行分析。结果表明,新泰市地下水环境较前人研究发生了较大的变化;丰枯水期主要阳离子为Ca 2+,阴离子由前人研究以HCO 3-为主变为以HCO 3-和SO 42-为主;丰枯水期地下水按TDS划分,均处于淡水和微咸水等级;水化学类型在空间上变化较大,出现了多种类型,以HCO 3·SO 4-Ca型为主,这也说明地下水环境受到外界的影响;新泰市地下水离子主要来源于硅酸盐岩和碳酸盐岩等的风化溶解,同时也受到人类生活、工业生产以及农药化肥过量使用的影响。
To identify the hydrochemical characteristics and ion sources of groundwater in Xintai city,29 groundwater samples were collected in September 2017 and May 2018.Statistical analysis,correlation analysis,Piper diagram,Gibbs graph and ion ratio were used to analyze the test results of water samples.The results show that the groundwater environment in Xintai city has changed significantly compared with previous studies.The main cation is Ca 2+,and the anions have changed from HCO 3-to HCO 3-and SO 42-in the flood and dry periods.Groundwater in both periods can be classified as freshwater and brackish water according to TDS.Substantial changes have taken place in hydrochemical types in space and many hydrochemical types,with HCO 3·SO 4-Ca as the main type,have appeared,which also indicates that the groundwater environment is affected by the outside world.Groundwater ions derive mostly from the weathering and dissolution of silicate rocks and carbonate rocks,and are also affected by human life,industrial production and the overuse of pesticides and fertilizers.
