摘要
为了解和掌握宿州市新汴河刘闸段下游河流水化学特征及水质状况,采用多元统计分析、水化学传统图示法、离子比例系数等方法,明晰了研究区河流水的水化学特征;同时利用SAR、RSC、盐度和碱度等参数,对其水质进行了评价。结果表明:研究区水化学类型为HCO_(3)-Ca.Na型,为沉积岩地区典型的溶滤水;水化学成因主要受岩石风化作用控制,且水体离子之间发生了阳离子交替吸附作用;灌溉性指标(RSC<1.25,SAR<10,盐度<15,碱度<4)表明,该段河流水灌溉适用性较好,适宜用于农业灌溉。
In order to understand and master the hydrochemical characteristics and water quality of the downstream river of Liuzha section of Xinbian River in Suzhou City,the hydrochemical characteristics of river water in the study area were clarified by multivariate statistical analysis,traditional hydrochemical graphic method and ion ratio coefficient.At the same time,the water quality was evaluated by using SAR,RSC,salinity,alkalinity and other parameters.The results show that the water chemical type in the study area is HCO3-Ca.Na type,which is a typical dissolved water in sedimentary rock area.Hydro⁃chemical genesis is mainly controlled by rock weathering,and cation exchange adsorption occurs be⁃tween water ions.Irrigation index(RSC<1.25,SAR<10,salinity<15,alkalinity<4)indicates that the river water irrigation in this section has good applicability and is suitable for agricultural irrigation.
