In order to analyze the main ecological factors affecting the distribution of Campanumoea javanica,explore its ecological suitable distribution area.In this study,geographic information system(ArcGIS)and maximum entropy model(MaxEnt)were used to simulate 119 geographical distribution points and 37 ecological factors,and identify the main environmental factors and suitable areas affecting the potential distribution of Campanumoea javanica.The results showed that the main environmental factors affecting the ecological suitability of Campanumoea javanica were the lowest temperature in the coldest month,the monthly mean value of diurnal temperature difference,the average annual precipitation and altitude.Among them,the average annual precipitation is 5℃,the monthly average temperature difference between day and night is 6℃,the average annual precipitation is 1 607 mm,and the altitude is 731 m.The potential areas of high suitability for Campanumoea javanica growth are mainly located in southwest Guizhou,eastern Sichuan,southeast Yunnan,Guangxi,northern Guangdong and central Fujian.The potential distribution data of Campanumoea javanica based on MaxEnt model can provide reference for its resource protection and utilization and cultivation base selection.
