华北山前平原不同含水组垂向水循环规律
|
摘要
地下水是华北山前平原的主要供水水源,其资源属性一直存在争议。以正定试验基地为研究区,通过分析地下水化学、氘氧同位素、14 C测年等在垂向上的变化特点,对比不同含水组地下水与大气降水的氘氧同位素含量关系,研究华北山前平原典型研究区504m深度内不同含水组地下水在垂向上的循环规律,确定360m为该区地下水含水系统的内部界限,其上构成浅层含水系统,其下构成深层含水系统。
Groundwater is the main water source in the piedmont plain of North China,but its resource attribute is always controversial.In this paper,taking Zhengding Test Base for the study area,the vertical variation characteristics of groundwater chemistry,deuterium and oxygen stable isotope,and 14C dating were analyzed,and the relationships of the contents of deuterium and oxygen isotope between different aquifers and the precipitation were compared.The results revealed the vertical hydrological cycle of different aquifers in the depth of 504 m in typical region of the piedmont plain of North China,which suggested that the depth of 360 m is the division for two aquifer systems.The shallow aquifer system was above the depth of 360 m,whereas the deep aquifer system was below the depth of 360 m.
