Abstract: Based on the meteorological data from 1980 to 2004 at the meteorological stations in Zhaotong City of Yunnan Province,the meteorological data in the planting regions of the high quality tobacco were analyzed in parallel,to assess the climatic suitability of the cured tobacco and the status of the ecological and climatic resource distribution in Zhaotong.The suitability devision for cured tobacco growing was remade by using indexes of the climatic suitability.The results showed that most parts of the Southwest Zhaotong and parts of the East Zhaotong were the most suitable regions for cured tobacco growing,where it belonged to north subtropical climate zone.The basin areas with the altitude from 1800 to 2000 m,the most parts of the mountain areas and the most parts of the mountain areas with the altitude from 900 to 1700 m were the suitable regions for cured tobacco growing,where it belonged to south temperate climate zone.
