摘　　要：通过实施水环境监测,本文研究了铁岭地区主要河流水体的主要离子分布特点,揭示了铁岭地区主要河流的水化学类别及形成因素,阐明了铁岭地区主要离子的来源。研究结果显示,铁岭地区地表水中主要的阳离子为Ca^(2+),占阳离子总和的51.46%;主要的阴离子为HCO_(3)^(-),占阴离子总和的66.28%;水化学类型是Ca^(2+)-HCO_(3)^(-)型;水化学特征主要受到蒸发结晶和岩石风化作用的影响,主要离子来源于岩石风化。该研究成果可为铁岭地区水资源保护和利用提供基本支撑。This paper examines the distribution characteristics of major ions in the surface waters of Tieling through the implementation of water environment monitoring.It reveals the water chemistry categories and formation factors of the main rivers in Tieling,clarifying the sources of major ions in the region.The results indicate that the predominant cation is Ca^(2+),accounting for 51.46%of the total cations,while the main anion is HCO_(3)^(-),comprising 66.28%of the total anions;the water chemistry type is Ca^(2+)-HCO_(3)^(-).The water chemistry characteristics are primarily influenced by evaporation crystallization and rock weathering,with major ions originating from rock weathering.These findings provide a fundamental support for the protection and utilization of water resources in the Tieling area.
