在野外采样的基础上，通过测试分析不同地段、不同深度含水层中的环境同位素（δ18 O‐δD ）特征，结合实际水文地质条件，分析了研究区地下水的补径排关系。结果表明：研究区内地下水主要接受大气降水补给，各含水层的垂向水力联系较弱；在垂向上氘氧同位素具有明显的分层性特点，总体上表现为随着地下水埋藏深度的加大，地下水的δ18 O、δD值逐渐偏负；通过氘过量分析表明各含水层均受到了现今大气降水影响。

On the basis of field sampling and actual hydrogeological conditions ,Analysis the relationship between recharge ,runoff and discharge via testing different lots at different depths in the aquifer environmental isotopes (δ18O‐δD ) features .The results showed that :in the study area ,groundwater recharge mainly by atmospheric precipitation ,each aquifers vertical hydraulic connection is weak;δ18 O‐δD has obvious characteristics of stratification in the vertical ,δ18 O ,δD value of groundwater gradually negative by the groundwater burial depth increased;it showed that all the aquifers are now affected by atmospheric precipitation by deuterium excess analysis .
