Using the DRASTIC method, the authors choose 7 parameters as evaluated index and set up the groundwater vulnerability evaluation system of Harbin area. The authors compile the subarea map of groundwater vulnerability of Harbin area. The results indicate that 17.1 percent of the city regions are of high vulnerability, which mainly occur along the Songhua River. This area has the highest risk for water pollution, and can be considered as the key protection region.
