Taking Cremastra appendiculata as the research object,by screening and combining 13 environmental factors,the maximum entropy model(MaxEnt)was used to study the changes of potential suitable areas in Anhui under modern and future climate(2021-2040).The results show that the prediction result of MaxEnt model is good;the main factors affecting the distribution of Cremastra appendiculata are precipitation and air temperature;under the current climate and three climatic scenarios in the future(2021-2040),the area of high and medium adaptive areas in Anhui is greatly reduced,and the centroid of highly suitable areas changes from northeast to northwest,and then to southeast.The study provides a reference for the discovery and protection of Cremastra appendiculata.
