To explore the potential distribution of Phyllostachys edulis in the global terrestrial area and the dynamic changes in its suitable habitats under future climate scenarios and to find the environmental variables that play a leading role in its distribution,this study analyzes the potential suitable areas of Ph.edulis across the globe and the variation trends using Arcmap,MaxEnt environmental niche model,environmental variables layers and the data of Ph.edulis distribution.The results indicate that:1)The main environmental variables limiting the distribution of Ph.edulis are the temperature seasonality(standard deviation×100),the mean temperature of the warmest season,the annual precipitation and the precipitation of the warmest season.The variables of temperature and precipitation are the main environmental variables that dominate the geographical distribution of Ph.edulis;2)Currently,the total potential suitable area of Ph.edulis is 7.284 million km2,mainly distributed in southeast Asia and southeast America,far exceeding the existing range of planting and introduction;and 3)Under the future climate scenarios,the total suitable area of Ph.edulis will increase,and the suitable bamboo growth area of different grades will change greatly,among which the areas of lowly suitable area will increase steadily while the areas of highly suitable area will decrease.Moreover,the potential suitable areas of Ph.edulis shows an overall trend of migration from low latitudes to high latitudes.This study would provide references for the planting,cultivation and introduction area selection of Ph.edulis,as well as for preventing and controlling the invasion of Ph.edulis along the"Belt and Road"Initiative and even across the world.
