    Abstract:
    The causes of geological hazards are rather complex due to many influence factor s, but they are mainly triggered by the change of weather conditions and affecte d by geological and geomorphic conditions. Taking Jinhua area as an example, on the basis of investigation about the geological and geomorphic conditions especi ally in the disaster zone, four gridregions with different geological hazards hiddenrisk level are plotted out. The finegrid forecast model of geological hazards is tested to be reliable, which is based on BP neutral network and rain fall data from mesoscale observation system. The method is proved to fit in with scientific rule and can contribute to increase the forecast precis ion. The forecast model will provide a tool for reducing the damage of hazards i n this area.
