摘要
根据西窑地区地表水、地下水、降水中同位素的组成特征，确定了该区雨水线方程，并以δ￣（１８）Ｏ高程效应，氚的埋深效应，论述了西窑水源地补给、径流条件以及它与源涡水源地的关系，即二水源地虽都开采三叠系基岩裂隙水，但不属于同一含水系统，说明西窑饮用天然矿泉水水源地选址合理。
According to the composition characteristics of isotopes in Xiyao surface water,groundwater and precipitated water,the equation of rainwater-line can be determined.By the eleva-tion effect ofδ￣(18)O and burial effect of tritium,the recharge of Xiyao water source,runoffcondition and their relation with yuanwo water source are discussed.Though they both arethe fissure water of Triassic system,yet they are not from the same aqueous system. Thisshows that the selection of Xiyao potable natural mineral water source is reasonable.
