【Abstract】An economic losses evaluation information system of rainstorm waterlogging disasters in cities is introduced. The system integrates multiple subjects such as meteorology, disaster, information science, and economics science. As a man-machine interactive system, it includes basic function, information query, data management, economic lossesevaluation, assessment report generation, user rights management and system management function modules. This system is made as the way of ‘WYSIWYG’. Direct economic losses and indirect economic losses are calculated by input-output model. Combined with the weather true information, this system can report the real-time direct and indirect economic losses of rainstorm waterlogging disasters, automatically generate defense countermeasure reports in typical waterlogged points, and provide the spatial distribution of disasters and economic loss. Finally, the system is conducive to improving the ability of disaster emergency management of government departments and reducing the economic losses from the disaster eventually.
