Abstract: Betimes and high efficiency method must be used to forecast pollution trend in the face of more and more serious problems of soil heavy metal pollutions. In this research, the soil heavy metal pollution forecast model and soil pollution heavy metal element overtake standard early warning model was established and forecast extension was developed based ArcView GIS support by GIS technique, and then realized forecast and early warning for soil heavy metal pollution. Lastly, taking Beijing City include its suburb as instances, warning its heavy metal pollution and forecast Pb element overtake standard fixed number of year and a good forecast result was gained.

Key words: heavy metal pollution, GIS, early warning, overtake standard year forecast
