摘要

Rainstorm-flood are one of the main meteorological disasters in Shanxi province, resulting in a large number of casualties, assets damage and economic losses. Based on the historical disaster data of rainstorm-flood, and considering the two aspects of disaster frequency and disaster impact, the hazard index model and classification standard of rainstorm-flood are constructed. The risk level of rainstorm-flood disaster in each county (district) of Shanxi is evaluated. Combined with the meteorological geographical regionalization of Shanxi, the plan of hazard zoning for rainstorm-flood disaster in Shanxi is put forward, which provides decision-making reference for regional disaster prevention and reduction.
