摘要

摘要: 文章利用2011年4月到2012年3月对梧州水文站控制断面进行的定期采样数据，分析了该断面河水中主要阴、阳离子的化学组成，并运用多元统计分析方法研究和探讨了河水化学组成变化特征。结果表明，梧州水文站控制断面河水水化学类型以Ca2+ + HCO3-型为主，Na+、Ca2+、Mg2+、HCO3-、SO42-、NO3- 主要来源于岩石的风化，K+ 、Cl-来自于人类活动的输入；河水中离子化学组成受水—岩作用和土壤表面离子交换作用影响，对河水溶质的贡献率分别为69.34％、17.10％。

Abstract: Wuzhou hydrological station is located in the upper reaches of the Xijiang river, with a catchment area of 327,006 km2, accounting for 94.6% of the Xijiang river’s total catchment. 85% of the water supply for Guangxi comes from this catchment. Thus, it is important to investigate the hydrological aspects of Wuzhou hydrological station. From April 2011 to March 2012 water samples were collected regularly and analyzed. Water quality characteristics were studied by means of multivariate statistical analysis. This paper focuses on the essential characteristics and evolutionary regularity of the water and factors influencing it. The results indicate that,(1) Ca2+ and HCO3- were the major ions in the water. The water chemistry was found to be of Ca2+ + HCO3- type. (2) The concentrations of K+, Na+,Mg2+, Cl- and SO42-were greatly affected by the surrounding environment, while Ca2+ and HCO3- concentrations were stable. (3) The major ions in water from Wuzhou hydrological station were mainly affected by water-rock interaction and ion exchange at the soil surface. Rock weathering and soil ion exchange accounted for 69.34% and 17.10%, respectively.
