Based on the frost date data of 52 meteorological stations over Shanxi Province from 1970 to 2009, the basic characteristics of the first and last frost dates and their changing trends were analyzed in this paper using linear trend estimation method, cumulative filter method and non-parametric statistical test method respectively, and the abrupt changing feature of the frost dates was also analyzed with Mann-Kendall method. The results show that the frost dates and frost-free period have obvious spatial and temporal changing features. Along with the latitude moving northward and the altitude rising high, the first frost appears earlier, the last frost occurs later, and the frost-free period becomes shorter. With the time changing over the past 40 years, the first frost event occurs later and the frost-free period becomes longer, while the last frost date fluctuates from year to year. For the abrupt changing feature, they all have one obvious abrupt change over the past 40 years. The abrupt change of the first frost date appears in 2000, while the abrupt changes of the last frost date and the frost-free period are detected in 1997. For the spatial distribution of their changing trend, the area in which the first frost date is postponed significantly includes the east of Jinzhong city, the north of Lüliang city, the west of Xinzhou city, the south of Yuncheng city, the northwest of Linfen city and the southern part of Datong city; the area in which the last frost date appears obviously earlier includes the east mountainous region of Jinzhong city, the eastern part of Lüliang Mountains and the western part of Xinzhou city; the area in which the frost-free period extends obviously includes the region near the Yellow River, the central-eastern part of the province and the south of Yuncheng city.
