Abstract：Evaluating the suitability of Honghuadajinyuan in Dali prefecture can provide scientific references for the rational cultivation of flue-cured tobacco and the optimization of the production space in the local area.Based on 19 climatic indicators，8 topographic indicators，11 physical and chemical property indicators of soil，as well as the data from 3O9 sampling points in the Honghuadajinyuan planting areas，the maximum entropy model （MaxEnt） was applied to construct the suitability evaluation model for Honghuadajinyuan planting. The results showed that： ① The key environmental factors affecting Honghuadajinyuan in Dali prefecture，ranked by descending order of contribution rate，were slope， topographic wetness index，precipitation seasonality，annual precipitation，relative position index，elevation，average daily temperature range， slope length factor， precipitation in the driest season， vegetation index，and soil pH value. ② The MaxEnt model demonstrated high accuracy in simulating the distribution of Honghuadajinyuan in Dali prefecture （ AUC=0.933） ： ③ The research on suitable zoning indicated that the advantageous planting areas of Honghuadajinyuan were mainly distributed in southern Heqing County，central Xiangyun County，central Eryuan County and other regions，accounting for 45.24% of the total cultivated land area of the whole prefecture. The zoning results were validated by sensory evaluation data from 48 samples，confirming their consistency with the actual situation.
