With the reality of planting tobacco in high elevation area:Weining county,Guizhou province (1900~2300m),the classification indexes of the climate regionalization of high quality tobacco were analysed in detail.The relationship between the surface heat and the growth of tobacco was given.The results show that not only the daily average temperature and its lasting time can be used to the climate regionalization indexes,but also the accumulated temperature,the temperature difference between day and night,the soil surface temperature and leaf temperature should be considered.The formar indexes of the average temperature in the mature period,the temperature in growth period,and the lasting days from growth to mature were corrected,and some supplemental indexes were suggested.
