Abstract Based on observational data from the national meteorological station in Jingdezhen City spanning 19542024 and regional stations from 20162024,this study analyzes the spatiotemporal distribution characteristics of subzero temperatures.The results indicate that these low temperatures primarily range from -2 to 0 ℃,occurring predominantly in January and February,with no such events recorded between April and September.The number of lowtemperature days has shown a continuous decreasing trend,with stronger lowtemperature intensities experiencing more significant reductions,alongside a notable decline in extreme lowtemperature events.Spatially,a pattern of "cold north and warm south"has emerged,with the northern Fuliang mountainous area identified as a highrisk zone,while the southern urban area and Leping City pose relatively lower risks.These findings can provide valuable references for the prevention of lowtemperaturedisasters and agricultural planning.
