The invention provides a method and system for dispatching resources needed by emergency repair of a power distribution network. Typhoon data and data of the power distribution network are obtained and analyzed, hazard-bearing body foundation data of the power distribution network are calculated, loss, caused by typhoon disasters, of the power distribution network is predicted according to the data, a loss prediction result of the power distribution network is obtained, data of the resources currently needed by the emergency repair are calculated, and the resources needed by the emergency repair of the power distribution network under the typhoon disasters are dispatched according to the data of the resources currently needed by the emergency repair. In the whole process, the resources of the emergency repair are reasonably allocated, the response speed of an emergency repair decision of the power distribution network is increased, the resources of the emergency repair can be allocated efficiently, passive management is converted into active management, the production safety of the power supply bureau is effectively guaranteed, and personnel causalities and property loss are reduced to the greatest extent.
