Vulnerability of groundwater resources is the basis for regional water resources planning and management. In view of the current lack of effective evaluation of groundwater resources, the groundwater resources was evaluated by taking the Yangzhou City Planning Area (Guangling, Hanjiang District) as example. Based on the characteristics of groundwater resources, hydrological and geological data, thirteen indexes were selected as the assessment index system, And the AHP was used to determine the index weight and finish the consistency analysis. The results showed that the groundwater vulnerability grade of Yangzhou urban planning area is Ⅱ-Ⅲ, the groundwater resources are relatively rich.
