同位素技术在黄河下游河水侧渗影响范围研究中的应用
Application of isotopic technique in the research of the affected range of lateral seepage of the down-Yellow River water
【摘要】 运用同位素技术确定河水与地下水的关系是当前研究的热点。利用在黄河下游悬河段4个剖面上采取的67个地下水和黄河水样,获得了δD、δ18O和T(TU)在空间和时间上的分布规律。潜水的氚值和δ18O的特征表明,黄河水与地下水水力联系密切,黄河对地下水的影响,南岸在郑州一带影响范围小,约5km,向东影响范围逐渐增大,在中牟和开封一带约为7~10km;在黄河北岸影响范围大约9~20km。
【Abstract】 One of current research hotshots in isotope hydrology is to determine the relationship between river and groundwater by isotopic technique. Spatial and temporal distribution of δD,δ18O and Tritium are obtained based on 67 groundwater and the Yellow River water samples in the four sections hanged along the lower reaches of the Yellow River. Characteristics of tritium and δ18O of phreatic water show that there existed a close hydraulic relationship between the Yellow River water and groundwater. The affected width by the river is narrow in Zhengzhou region in the south river bank with the width of about 5 km. The affected width increases gradually eastwardly,which is about from 7~10 km in Zhongmou- Kaifeng region. However, the affected width is larger in north bank than in south bank. The typical width is from 9 ~ 20 km.
