Abstract: Vulnerability is one of the key scientific problems in disaster research,and the study on vulnerability of hazard affected body can provide effective support for hail disaster risk prevention.After a review of the basic concepts of vulnerability,the domestic and overseas research progress of vulnerability on the base of hailpad monitoring，remote sensing retrieval and hailfall simulation experiment on crops,buildings and automobiles to hail hazard were summed up The results showed that the way of data gathering,the indicators of hazard intensity and the fitting function of vulnerability were differently obtained by different scholars in vulnerability assessment,but the research of mechanism and quantification would be appreciated in the future（1）In the data acquisition of hail,crops were mainly based on hailpad monitoring and experimental stimulating,while the buildings and cars depended on radar remote sensing inversion（2）There was a wide variation in the primary indicator selection,afterwards,the kinetic energy was selected to stand for the intensity of hail by many researchers（3）Some linear and non linear vulnerability functions had been developed,and the Logistic curve could be chosen as the best function to predict hail disaster vulnerability for crops,automobiles and buildings On these basis,thus producing the conclusion that the research on a model for vulnerability formation processes to lay the foundation for hail disaster risk study should be strengthened in the future.
