【摘要】 石头口门水库为长春市重要的水源地,为查明该地区地下水来源及年龄,采集地表水和地下水等不同水体同位素样品,并测试D、18O和氚,分析其同位素特征。结果表明,石头口门上下游地下水主要补给来源于大气降水,地下水年龄普遍较轻,多数10 a之内,部分为核爆炸时期与现代水混合水。地下水与地表水联系比较密切,深层地下水受到地球化学作用影响较深。更多还原

【Abstract】 In order to study the source and age of groundwater in the middle reaches of Shitoukoumen Reservoir,the isotope samples of various kinds of water is collected,the 2 H,18 O and 3 H is detected. The isotopes characteristic of research area is analyzed. The results show that the source of groundwater in research area is precipitation. The age of most groundwater is smaller than 10 yours,some groundwater source is the mix of modern water and nuclear explosion period water. The contact of surface water and groundwater is close. The deep groundwater is influenced by geochemistry effect.更多还原
