The invention relates to a GIS-based information visualization system. The GIS-based information visualization system comprises a meteorological information module, an emergency resource management module, a power grid information module, an auxiliary research and judgment module, a first-aid repair information module and an information reporting module which are in communication connection with an information display visual display module, wherein meteorological information, resource management information, power grid information, first-aid repair / maintenance information and auxiliary research and judgment information form a multifunctional sharing mechanism of a visual platform, and optimal scheduling, optimal monitoring, minimum cost and load balancing of a power system are achieved. Emergency disposal and commanding are more accurate and efficient, and a situation judgment, prediction analysis and emergency commanding integrated technical supporting platform is formed, and a linkage mechanism is established, and quick power recovery is guaranteed, and losses are reduced to the maximum extent.
