North China Plain, including the Beijing Municipality, Tianjin Municipality, Hebei Province and Henan Province, all the plain, the Yellow River in Shandong Province, north of Plains, a total of 19 prefecture-level cities, 227 county-level administrative units, with an area of 139,238 sq km.
The "Atlas" reveals the full description and structure of the regional hydro-geological characteristics of the dynamic characteristics of ground water level and water chemistry characteristics, groundwater isotope distribution, history and status of groundwater exploitation, groundwater mining-induced environmental geological problems, is by far the most informative comprehensive and systematic research of groundwater in North China Plain.
"Atlas," contains a variety of maps 112, divided into cladogram, the groundwater system, groundwater loop evolution, groundwater resources and functions of some four to administrative divisions, physical geography, Quaternary geology and lithofacies palaeogeography began with a system partition of groundwater, aquifer group floor elevation, hydro-geological profile and groundwater water chemistry and hydro-geological parameters of the space to display the characteristics of groundwater systems to different periods of the dynamic field of groundwater and groundwater isotopes to reveal the characteristics of groundwater to ring evolution in groundwater resources evaluation, evaluation of groundwater potential, evaluation of groundwater and groundwater storage capacity based on the functional assessment reveals the ability of the sustainable use of groundwater
