Geological disaster early warning method and system based on regional analysis

The invention discloses a geological disaster early warning method and system based on regional analysis. The method comprises the following steps: dividing a target to-be-monitored region into a plurality of first monitoring regions and a plurality of second monitoring regions on a remote sensing image; establishing a corresponding relation between the first monitoring areas and second monitoring areas, wherein each second monitoring area corresponds to at least one first monitoring area; acquiring first monitoring data; converting the first monitoring data into monitoring data for estimating a second monitoring area as second monitoring data; and performing geological disaster early warning on the second monitoring area according to the second monitoring data. According to the geological disaster early warning method and system based on regional analysis, the monitoring data of the corresponding first monitoring area is converted into the pre-estimation data of the second monitoring area through the corresp
