Abstract: By collecting the geographical distribution information and 19 environmental factors of 11 common broad-leaved species in Yunnan, MaxEnt model and ArcGIS spatial analysis technology were used to simulate the potential geographical distribution of the 11 species in China under the current climate scenarios.Therefore, the relationship between the habitats of the 11 different broad-leaved species and climatic factors was studied. The results showed that 4 nationally distributed tree species (Quercus variabilis, Pistacia chinensis, Aleurites fordii, and Toona sinensis) were mainly affected by temperature, among which minimum temperature of coldest month had the greatest impact, at −12-11 ℃. Annual mean temperature took the second place, followed by mean temperature of driest quarter, 9-24 ℃ and −4-21 ℃, respectively. The 4 distributed tree species in southwest China (Yunnan, Guizhou, Sichuan, Chongqing) including Populus yunnanensis, Alnus ferdinandicoburgii, Ficus glaberrima, and Magnolia delavayi were mainly restricted by temperature changes, and the annual temperature range was about 14-28 ℃. The 3 distributed tree species in Yunnan (Gleditsia japonica var. delavayi, Celtis tetrandra, and Yulania campbellii) were mainly affected by the annual mean temperature, which was about 12.5-22.5 ℃.
