In order to study the hydrochemical characteristics and their possible controls for the chemical composition of the water from the Niyang River Basin, 30 samples were collected from wells, springs, and the river in 2014 and major ion concentrations were measured. Descriptive statistics, the Gibbs figure, an ion ratio, and Piper triangular diagrams were used to investigate the hydrochemical characteristics, influencing factors, and hydrochemical evolution of the water in the basin. The results showed that the major cations in this water were Ca and Mg, accounting for more than 84% of cations and the main anions were HCO and SO, accounting for more than 97% of anions The hydrochemical typology of the water is HCO·SO(SO·HCO)-Ca·Mg (Mg·Ca). The total dissolved solids (TDS) in the water ranges from 79.11 to 290.48 mg·L with an average of 165.21 mg·L. The chemical composition of water samples is located to the left of the Gibbs model, which indicates that the chemical process of Niyang River Basin are controlled by rock weathering. According to the principal component analysis and correlation analysis, the hydrochemical composition is controlled by silicate weathering, however, carbonate weathering also plays an important role.
为了研究尼洋河盆地水体的水化学特征及其对化学成分的可能控制因素，2014年从井、泉和河流中采集了30个样本，并测量了主要离子浓度。采用描述性统计、吉布斯图、离子比值和派珀三角图来研究该盆地水体的水化学特征、影响因素和水化学演化。结果表明，该水体中的主要阳离子为Ca和Mg，占阳离子总量的84%以上，主要阴离子为HCO和SO，占阴离子总量的97%以上。水体的水化学类型为HCO·SO(SO·HCO)-Ca·Mg (Mg·Ca)。水中总溶解固体(TDS)范围为79.11至290.48 mg·L，平均为165.21 mg·L。水样的化学成分位于吉布斯模型左侧，这表明尼洋河盆地的化学过程受岩石风化控制。根据主成分分析和相关分析，水化学组成受硅酸盐风化控制，但碳酸盐风化也起重要作用。
