Abstract :
This paper has improved the DRASTIC evaluation model, established the DRASTMC model. It uses parameter system method and combines GIS processing technology to assess the groundwater intrinsic vulnerability in Guangzhou. The results showed that there is generally high vulnerability of groundwater in Guangzhou. The indexes of intrinsic vulnerability is 121.5~252, Overall groundwater vulnerable to pollution, But there are more obvious regional differences, and it can be divided into five vulnerability grade areas.
