摘要: 蛤蟆通流域是我国东北地区主要的高标准基本农田建设区,掌握其水化学特征规律,可以为该区水质评价和水文循环机制的进一步研究提供参考,为高标准农田的建设积累理论依据。结合蛤蟆通流域水文地质调查项目的数据,运用Piper三线图、相关性分析及ArcGIS空间分析技术等多种方法综合分析了地下水化学特征及其成因。结果表明:沿地下水径流方向地下水化学类型由HCO3-Ca型和HCO3-Ca+Mg型转化为HCO3-Na+Ca型;地下水水化学作用以溶滤作用和阳离子交替吸附作用为主。

Abstract: Hamatong Basin is a high-standard fundamental farmland construction area in northeast China, grasping its groundwater hydrochemical characteristics can provide reference for further studies on the water quality evaluation and hydrological cycle mechanism, and accumulate theoretical basis for the construction of high- standard farmland. Based on the data of hydrogeology survey, we comprehensively analyze the groundwater hydrochemical characteristics and the genesises through Piper diagram, correlation analysis, ArcGIS and so on. The results show that along the flow direction of groundwater, the chemical type of shallow groundwater changes from HCO3-Ca and HCO3-Ca+Mg to HCO3-Na+Ca; the main factors influencing the groundwater chemical characteristics are leaching and alternative adsorption of cation effects.
