摘要：According to the field investigation data, a meteorological forecast and alarm model of geologic disasters in Hefei Area has been established. This model was based on GIS raster data model in order to be integrated with GIS Digital Terrain Model (DTM) Component Object Model (COM). Some important factors that put premium on geological hazards, such as intraday and five-day forecasting and liminal precipitation, subareas of geologic disasters, have been considered in the model. The model has been integrated with forecast and alarm information system based on GIS seamlessly by the way of using ComGIS. The meteorological forecast and alarm information system of geologic disaster can be used to publish the forecasting and alarming information of geologic disaster according to the intraday and five-day forecasting precipitation from day to day in rainy seasons every year in Hefei Area. The successful establishment of the meteorological forecast and alarm information system of geologic disasters in Hefei Area demonstrated that this integrating method is feasible and it has the value of practicality and popularization in a certain degree
