摘要：

Factor analysis is useful for interpreting commonly collected groundwater quality data and relating those data to specific hydrogeologic process. Twenty two groundwater quality samples collected from wells in the second confined layer of Suzhou City were analyzed for major dissolved constituents by factor analysis. Correlations among 11 hydrochemical parameters are statistically examined. Three main factors which explain over 75.01% of the total groundwater quality variation are recognized. Factor 1, composed of concentrations of Ca2+, Mg2+, Cl- , Fe2+, CO2, Mn2+ and pH, represents the influence of water-rock interaction on groundwater quality. Factor 2, composed of concentrations of NH4+ and COD, reflects the impact of reductive organic rich environment on groundwater chemical compositions. Factor 3 including concentration of Na+ shows the effect of cation exchange on groundwater quality.
