Abstract: For defining the climatic similarity between Yunnan and Zimbabwe and optimizing distribution of fire cured tobacco cropping in Yunnan,the climatic similarity between two regions was analyzed,based on the 1∶250000 grids climatic data of Yunnan,and climatic factors.The results showed that the climate for fire cured tobacco cropping in Yunnan was significant similarity to that in Zimbabwe,which divided by Ailao mountain.The climatic similarity in east of Ailao mountain was higher than that in west of Ailao mountain.There was also similarity to Zimbabwe in south Yunnan where never planted fire cured tobacco before.Most of fire cured tobacco cropping region in Yunnan were low temperature,overcast or rainy and scant lighting.

Key words: Yunnan, Yunnan, Zimbabwe, Similarity, Fire cured tobacco
