[Evaluating ground water vulnerability in West Lake Watershed by using DRASTIC model].
Supported by Blackland GRASS Geographic Information System (GIS), the basic and special environmental databases of West Lake Watershed were established. The vulnerability map of ground water pollution was calculated and drawn by integrating GIS and DRASTIC model. Comparing to the present situation of land use, critical area of ground water pollution had been determined. The residential area accounted for 14.7% of the high susceptible area, and wastewater in the residential area should be piped and treated first.
