Application of Isotope Techniques in the Groundwater Source Planning of the Yubei Plain in Henan Province

For valuation of the shallow groundwater,because of the lack of awareness of groundwater renewal,exploitation of groundwater resources can be estimated too high in the past,the exploitation strength in many areas is much higher than the rate of natural regeneration of groundwater,which is resulting in a series of environmental problems due to groundwater exploitation.Taking full account of the recoverability of groundwater,the isotope T(3H) is used to estimate the update rate of shallow groundwater and groundwater age.The article is also based on the groundwater resource evaluation and lays the groundwater resources planning in order to enable the sustainable utilization of groundwater resources and protect the geological environment for the benefit of future generations.
