| 中文摘要 |
| 阆中市思依镇地区的水体主离子特征受该地区地质条件、地形地貌以及水文气象条件等因素影响,分析该地区的水化学离子特征对掌握地下水类型、成因以及水质情况具有重要作用. 运用统计学、Piper三线图、Gibbs图、相关性分析、主离子比例关系和平衡分析等方法对阆中市思依镇河水和地下水水样中的主离子测试结果进行分析,表明河水和地下水水体阳离子中Ca2+和Mg2+占主要优势,阴离子中HCO3-占主要优势,水化学类型主要有HCO3-Ca型、HCO3+SO4-Ca型和HCO3-Ca+Mg型. 水体离子主要受岩石风化作用过程中溶滤作用影响,并以方解石和白云石的溶解为主. |
| 英文摘要 |
| The characteristics of main ions in Siyi Town, Langzhong City was influenced by geological conditions, topography and hydrological and meteorological conditions and other factors. Here we analyzed the groundwater ions characteristics which will play an important role in mastering the groundwater types, chemical origin and water quality in this area. The testing data of main ions in river water and groundwater in this area were analyzed with statistics, Piper diagram, Gibbs figure, and correlation analysis, proportional relationship of main ions and equilibrium analysis method analysis. The results showed that Ca2+ and Mg2+, and HCO3- dominant among cations and anions, respectively, and the hydrogeochemical types can be classified into HCO3-Ca type, HCO3+SO4-Ca type and HCO3-Ca+Mg type. Main ions of all water are mainly affected by leaching effect in rock weathering process, which are dominantly dissolved from dolomite and calcite. |
