摘　　要：过去,在浅层地下水资源评价中,由于对地下水更新能力的认识不够,对地下水的可开采资源量估计的过高,因而许多地区的开采强度大大超过地下水的天然更新速率,产生了一系列与地下水开发利用有关的环境问题。在充分考虑了地下水的可恢复性,使用同位素T(3H)估算了浅层地下水更新速率与地下水年龄,开展地下水资源评价的基础上,制订地下水水源地规划,这样做可使地下水资源可持续利用,保护好地质环境,为后代造福。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.
