| Abstract: | : Using daily Minimum temperature and frost days,geographic information and national economic statistics data of Shannan Tibet．Started with four aspects including the risk of factors causing frost disaster,the sensitivity of disaster environment,vulnerability of hazard affected body and the ability of disaster prevention and mitigation,the weights were determined by using expert scoring method and The analytic hierarchy procees (AHP),frost disaster risk assessment model was established with the help of GIS technology,finally,the frost disaster risk zoning work in Shannan was completed．The results show that the high and second risk areas were in the Nagarze ,most of Come,Northwest of Cona,West of Lunze,West of Lhozhag,Southwest ofGon- |
