This paper introduced three means to enhance the precision of assessment of groundwater resources examining the replenishment of the shallow groundwater: 1) combination of elements and change in isotope contents in groundwater can reflect the change in quantity of groundwater resources. Recharge items of groundwater resources are determined and portioned in this paper with isotope techniques; 2) the recharge quantity of the local river with ¹³¹I element flowing velocity is calculated; and 3) the proportion recharged by the Yellow River the in groundwater resources is calculated with contents of ¹⁸O. As a result, precision of assessment of groundwater resources is indirectly enhanced.
