Abstract Based on the surface meteorological data of 11 national meteorological stations in the main walnut producing areas of central and southern Hebei province from 1960 to 2017,the normal distribution,Gumbel distribution and Weibull distribution function are used to fit the minimum temperature of walnut flowering period.And a probability model of low temperature freezing damage is established.By fitting and analyzing the data of distribution function,the conclusion can provide theoretical basis for establishing scientific low temperature forecast and early warning model and risk assessment planning.
