Hydrological disaster affected area identification method and system, storage medium and electronic equipment

The invention relates to the technical field of big data processing, and particularly discloses a hydrological disaster affected area identification method and system, a storage medium and electronic equipment, and the method comprises the steps: constructing a sub-literature database corresponding to a target hydrological disaster according to a terminology set corresponding to the target hydrological disaster; accurately matching each region name in a sub-document database, marking and screening appearance characteristics of each region name in the sub-document database, and obtaining each screened region name; and determining each screened region name as a disaster-affected region corresponding to the target hydrological disaster when the included multiple geographic data corresponding to each screened region name meets the preset recognition precision. The hydrological disaster area identification method can reduce the time consumption of hydrological disaster area identification, overcomes the problem of
