| 摘 要： | 结合鄂尔多斯白垩系盆地北区环河含水岩组地下水水化学数据,以地下水中六大离子(K++Na+、Ca2+、Mg2+、Cl-、SO24-及HCO3-)和TDS为变量,应用对应分析法对环河组地下水水化学特征进行了分析。结果表明:研究区66个样本点被分为3个区,Ⅰ区地下水水化学类型多为SO24-、SO24--Cl-型,Ⅱ区多为HCO3--SO24--Cl-型,Ⅲ区多为HCO3-、HCO3--SO24-、HCO3--Cl-型。

| Abstract: | Combing hydrogeological conditions in north Ordos cretaceous basin,six ions(K+ +Na+,Ca2+,Mg2+,Cl-,SO2-4and HCO-3)and TDS used as variables,hydrochemical characteristics of groundwater in the Huanhe River ground were analyzed by the application of correspondence analysis.The results show that 66 sample points in the study area are divided into three region.RegionⅠ’s groundwater chemical types mostly are SO2-4 and SO2-4-Cl-,regionⅡ’s groundwater chemical types mostly are HCO-3-SO2-4-Cl and regionⅢ’s groundwater chemical types mostly are HCO-3,HCO-3-SO2-4 and HCO-3-Cl-. |
