Abstract: Xiangxi Autonomous Prefecture is located in the northwest of Hunan, and most of the tobacco planting areas are distributed from 350 to 1150m. Due to the difference in topography and elevation, the climatic conditions of different tobacco planting units differ greatly. In order to understand the climatic characteristics of the various planting units, it is of great significance to arrange the transplanting period of flue-cured tobacco reasonably and increase the maturity. For this purpose, the automatic weather stations established at four different altitudes in 2016 and 2017, based on the observation data of two consecutive years, analyzed the variations of the temperature and the boundary temperature with the altitude, and then combined the mountain meteorological elements. The model was calculated to analyze the evolution characteristics of temperature at different altitudes, and the optimal transplanting period and the best harvesting period for each planting unit were determined. It can provide important reference for reasonable arrangement of production in various tobacco-producing areas in Xiangxi Autonomous Prefecture.
