Abstract: | The Quaternary groundwater system in the North China Plain is formed mainly through the terrestrial water flow action on the
united geological and tectonic backgrounds. The analysis of groundwater dynamic field, simulation of groundwater geochemistry,
and the14C dating and extraction of isotope information have provided more evidence for recognizing and assessing the evolution of
groundwater circulation system and studying the past global changes. The exploitation and utilization of groundwater on a
large scale and overexploitation have given rise to the decline of regional groundwater level, change of flow field, decrease
of water resources and downward movement of saline water body. The water environment has entered a new evolution stage in
which it is intensely disturbed by the mankind’s activities.
