Resumo

Aiming at the real-time evaluation of rainstorm disaster risk level methods that lack of elaborate and quantitative presently, this paper applied meteorological data, historical disaster data, height and distance from the sea of Guangxi, and confirmed the identification technology and data sequence building method of hazard -formative factors of rainstorm of Guangxi based on hazard-bearing body , the hazard -formative environment, hazard -formative factors ,and anti-disaster capability. Real-time evaluation model and grade index of rainstorm disaster risk level were constructed for different hazard-bearing body ,such as agriculture and social economy, based on risk, subsequently environment fragile degree, vulnerability and anti-disaster capability. And then rainstorm risk level real-time evaluation system was developed, with real-time evaluation model as the core, by the GIS secondary development technologies, to simplify and standardize the operating process of rainstorm risk level real-time evaluation. Evaluated the violent typhoon named Neuchatel on September 29, 2011 by using this system, the results of experiments consistent with disaster condition.
