Zusammenfassung:The invention belongs to the technical field of power grid icing monitoring and control, and discloses a method for establishing a micro-topography and micro-meteorological database for power grid icing prevention and disaster reduction. The method comprises the following steps of: acquiring power grid data, an obtained DEM division region micro-topography type and DEM data extraction topography factors; manually observed icing data and online monitoring data are processed, interpolation processing is carried out on meteorological parameters through multiple algorithms, and icing parameters in the icing process and meteorological elements in the ice observation period are extracted; and performing spatio-temporal feature matching on the icing sample meteorological and topographic factors, and establishing a micro-topography and micro-meteorological database suitable for power grid anti-icing disaster reduction. According to the invention, water vapor area terrain division and micro-terrain accurate classifica
