Abstract：Using daily meteorological data from 12 national meteorological observation stations in Shangrao region from 1978 to 2022 winter,the daily average temperature ≤1 ℃,daily minimum temperature ≤0 ℃,and duration ≥3 days were taken as a low-temperature freezing weather process.The daily average temperature,daily average minimum temperature,cumulative precipitation,and duration of the process were calculated and normalized into dimensionless data.The weights of each factor were determined using the Analytic Hierarchy Process (AHP) to calculate the comprehensive meteorological index.Using the quartile method for analysis,the results show that the comprehensive meteorological index of low-temperature freezing in Shangrao City has four disaster levels:[0,0.142],moderate (0.142,0.192],severe (0.192,0.275],and extremely severe (0.275,1].This index research can provide technical support for Shangrao City to carry out agricultural catastrophe insurance compensation and help rural revitalization,and provide important basis for decision-making departments in disaster prevention and relief.
