Abstract :
With the development of energy base in Ordos basin, the deficiency of groundwater becomes serious. The paper used the cluster analysis to study on the lots of chemical analysis data in shallow aquifer of Cretaceous. The result shows that In the east of Anbian-Sishililiang-eruokeqi watershed, the watertype of samples were mainly HCO3; in the west of watershed, the watertype were decided by the groundwater circulation, near the watershed, the main anion were HCO3-, at the edge of the study area, the samples´ main anions were Cl- and SO42-.
