Taking the plain groundwater system of Hohhot in Inner Mongolia as an example, the authors made vulnerability division of groundwater system by adopting the traditional DRASTIC and some new isotope dating methods based on concentrations of ³H,  ³H and ¹⁴C.The methods of vulnerability evaluation of groundwater system were investigated. The evaluation results of the DRASTIC show that the shallow groundwater system can be protected against the pollution in vertical direction. This paper also points out the respective advantages and disadvantages of the two means. Finally, it is pointed out that DRASTIC and isotope-assisted methods should be adopted on the basis of regional hydrogeological conditions, current groundwater exploitation situation and city development planning for comprehensive zoning of groundwater systems.
