Heavy Rain Disaster Vulnerability Analysis Advanced System

摘要

The present invention relates to a heavy rain disaster vulnerability analysis advanced system, and includes an output unit that divides the current vulnerability rating analysis unit and the future vulnerability rating analysis unit into a current vulnerability rating analysis unit and a future vulnerability rating analysis unit for each analysis unit, and selects and outputs a lower grade among the ratings of each analysis unit, wherein the current vulnerability The rating analysis unit consists of a current climate exposure analysis unit and a current urban sensitivity analysis unit, and the result of each analysis unit is calculated as an average of two grades in any one of 1 to 4 grades, and the future vulnerability grade analysis unit is a future climate exposure It consists of an analysis unit and a future city sensitivity analysis unit, and the result of each analysis unit is characterized in that it is calculated as an average of two grades in any one of 1 to 4 grades. By improving the spatial analysis unit from the existing aggregate unit unit to the grid-based unit, disaster vulnerability rating information is provided in units of parcels of the continuous cadastral map, resulting in excellent accuracy and effectiveness, and local rainwater runoff in the current vulnerability index of heavy rain disaster vulnerability analysis It has the characteristic of linking with the vulnerable population by applying the cumulative CN index and the relative lowland index, which are urban sensitivity indexes that can reflect characteristics.
