The zonation of hail risk is researched according to observed meteorological data, historical disaster data and fundamental geographic data in Tianzhu Tibetan autonomous county where hail disaster frequently happens. An evaluation model for hail risk is established consisting four indexes, namely hazard of disaster-inducing factor, sensitivity of environment to hail disaster, vulnerability of hazard-affected body to hail disaster, and capability of disaster reduction and relief. Furthermore, GIS technology is adopted to obtain the zoning of hail disaster risk. Results show that the hail risk rises from the north to the south in Tianzhu Tibetan autonomous county. Hail risks in Huazang temple, Dongping, Shimen and Dachaigou, and part of Tanshanling and Saishensi are the highest, followed by Haxi, Duoshen and Xidatan; the hail risks in east Songshan, southwest of Danma and Qilian are the lowest.
