基于MaxEnt模型的濒危物种五小叶械潜在适生区预测
Prediction of Potential Suitable Distribution of Acer pentaphyllum Based on MaxEnt
摘要
Abstract
Acer pentaphyllum is a rare and endangered species found only in Sichuan.It is of great signifi-cance to predict the changes of its potential suitable areas.This study used MaxEnt to predict the potential suitable habitat of A.pentaphyllum in the climate scenarios of Last Glacial Maximum(LGM),the pres-ent,and 2070s in China with 40 distribution points.Southwest of China is the suitable area of A.pen-taphyllum,and the AUC value of training data under the three climate scenarios is 0.999,indicating the high accuracy of the prediction results.The Jackknife method and climate contribution rate show that pre-cipitation in the hottest season is the most important environmental variable affecting the distribution of A.pentaphyllum.During the Last Glacial Maximum,A.pentaphyllum had some refugia in the Hengduan Mountains.The Yalong River basin in southwestern Sichuan has been the core distribution area of A.pen-taphyllum for a long time.Since the LGM,the suitable habitat level in northeastern Sichuan has de-creased.In 2070s,the area of total habitat and high-suitable habitat will be expanded to higher latitudes.关键词
