Groundwater vulnerability refers to the inherent sensitivity and susceptibility of a groundwater system to contamination or quality degradation under the influence of natural conditions and human activities.As a national core grain-producing region and a significant economic zone,Henan Province relies heavily on the sustainable utilization of groundwater resources for regional development and ecological security.The study on groundwater vulnerability in the plain area of Henan Province can provide scientific support for groundwater protection and pollution prevention and control.Taking the plain area of Henan Province as the research area,this paper comprehensively analyzes its physical geography,hydrogeological conditions and human activities,and adopts the DRASTIC method to assess groundwater vulnerability.The results show that the groundwater vulnerability of the study area is generally high,and shallow groundwater burial depth is the main cause.
