Analysis on Rainstorm Disaster Risk in Liaoning Province Based on PPD Model
摘要
Abstract
According to the data of daily precipitation and rainstorm disaster loss in 1 976 -2006 of Liaoning province and based on the theory of natural disaster risk,the probability of occurrence of different levels rainstorm are analyzed by PPD model.Acquiring index of rain storm disaster by establishing damage index system,combined with ArcGIS Technology,assessment and regionalization of rainstorm disaster risk of Liaoning province are done. Results show that:①The possibility of occurrence of in Liaoning Province decrease as the rainstorm level increase. Level 1 to level 4 is mainly detected but level 5 is merely detected,furthermore,the property of rain storm from level 2 to level 5 is mainly decreased from southeast to northwest (level 1 decrease from northwest to southeast);②As for the whole province,the risk of rainstorm disaster and loss is grandly coincided with features of attributions, which is increasing from north to south,from west to east,decrease from southeast to northwest;③PPD model is suitable to calculate possibility of factors of disaster in that the consequence of research based on this is coincidence with risks of Liaoning rain storm.关键词
