Abstract

Abstract

Groundwater pollution risk assessment is important for the rational development and utilization of land and groundwater pollution prevention. By analyzing the characteristics of shallow groundwater in the plain area of Xi’an, a conceptual model of groundwater pollution risk assessment including groundwater vulnerability, pollution source load and water function value was established, and the groundwater pollution risk of the plain area of Xi’an was evaluated. The results showed that the high, medium and low risk areas of groundwater pollution in the plain area of Xi’an accounted for 0.2%, 28.8% and 71.1% of the total study area, respectively. The medium and above risk areas of groundwater pollution in the plain area were mainly distributed along the banks of the Weihe River in Zhouzhi County, along the Weihe River in Chang’an District, and along the Weihe River in Lantian County. The high groundwater vulnerability and relatively strong pollution source load were the main reasons for the relatively high pollution risk in the region.
- groundwater pollution risk,
- vulnerability,
- pollution source load,
- water function value,
- plain area of Xi’an
