Abstract：This paper investigated the response of chemical properties of groundwater in Jing Huiqu irrigation district to irrigation using water from different sources.Groundwater at town of Qiaodi town were sampled for hydrochemical analysis,and the chemical compositions and their temporal changes in the areas irrigated using different waters were studied.The results showed that the hydrochemistry of the samples was dominated by Na+ Mg—HCO3+SO4+C1 and the shallow groundwater was alkaline.The significant of ions that affect TDS was in order of SO24-＞Cl-＞Ca2+＞Mg2+.The factors that affect the chemical composition of the groundwater was evaporation,cation exchange and dissolution-precipitation.The concentrations of all ions in the well-irrigation areas were higher than that in the canal-irrigation areas.The concentration of Ca2+ in the two areas irrigated with groundwater and canal-surface water differs considerably.What led to the temporal changes in Ca2+ and Na+ was irrigation and precipitation.Therefore,canal-water irrigation should be considered firstly if it is available,and the groundwater quality management should be improved when rainfall is intensive or when irrigating the fields.
