Based on the glaze data of 83 weather stations，an analysis is made of the glaze weather processes in the past 50 years, and the temporal and spatial distribution of glaze is revealed. By means of the selfdeveloped automatic weather information analysis methods, the historical glaze data are processed, and some key information is extracted, such as the dates of beginning and ending, durations and affected areas of glaze events. The reoccurrence period analysis of glaze is made of the durations, affected areas of glaze weather and the annual numbers of glaze days. The results show: (1) Glaze occurred mainly during winter, especially in February, sometimes in spring or autumn at highaltitude stations. (2) The highest probability of glaze occurrence was along the middle and northern coast of the Poyang Lake, and the least in the northeastern and northwestern Jiangxi Province; there are more glaze events in the mountainous area than in the plain and hilly areas. (3) The largescale and longlasing glaze weather in the early 2008 induced great cold damage, with the affected area and duration breaking the recodes of the recent 50 years.
