摘要
蓟县中上元古界岩溶裂隙含水系统,是由不同贮水空间的含水岩组及不同水文地质意义的断裂构造在空间上组合而成。该含水系统地下水排泄方式较复杂,在基岩覆盖区,顶托排泄量占总排泄量的59.2%。该含水系统的地下水动力场与地下水中化学组分的演化规律具有较明显的一致性,具有三维径流特征。
The aquatic system of Middle-upper Proterozoic karst cracks in Jixian is composed of rock assemblages with different distribu- tion in space and fault structures with different fuctions in hyd- rogeology.The drainage pattern of the aquatic system is complex. In rocky area,the drainage of the top beds of the system makes up 59.2% of the total drainage.The dynamic system changes in step with the change of chemical composition of the graound- water,showing the features of three-dimensional runoff.
