摘　　要：通过分析石羊河流域地表水与地下水的水化学特征,可以了解石羊河流域地表水与地下水的相互转化关系。研究结果表明:(1)武威盆地,在山前地带,出山河水入渗转化为地下水;溢出带地下水以泉的形式转化为地表水;进入细土平原后,河水又补给地下水;在农灌区引河水又通过田间入渗反补地下水。(2)民勤盆地,地下水主要通过引水灌溉和河水补给。Based on the analysis of the chemical character of water in the Shiyang River catchment, the study illustrated the interaction of groundwater and surface water along the Shiyang River. The results showed that：（1）in Wuwei basin, groundwater got recharge from river at mountain front and discharged to the river at the edge of extravasation zone, in alluvial plain down stream, the aquifer got water from river during high-water period or during irrigation period and discharged to the river during low-water period; （2）in Minqin basin, groundwater got water from surface water through irrigation in agricultural land and from river.
