Abstract: To reveal the impact of climate change on the suitable habitat of Phoebe chekiangensis,a systematic study was conducted on the distribution and variation patterns of the suitable habitats of Phoebe chekiangensis in Zhejiang Province by using ecological niche models and climate data.A total of 12 variables were selected, including altitude, precipitation in the wettest month, precipitation in the driest month, soil depth, average temperature in the wettest season, isothermality, slope aspect, slope gradient, annual temperature range, minimum temperature in the coldest month, average diurnal temperature range, and precipitation in the driest season.The results showed that the average AUC value was 0.858,with a standard deviation of 0.042,indicating a high degree of credibility of the prediction.The total area of the suitable habitats of Phoebe chekiangensis（suitability value ＞ 0.05） was 52700 km²,among which the areas of the highly suitable, moderately suitable, and low-suitable habitats were 7400 km²,15000 km²,and 30300 km² respectively.Most areas of Lishui and Quzhou, the southern mountainous areas of Jinhua, and the southwestern mountainous areas of Wenzhou were suitable for the growth and development of Phoebe chekiangensis.Altitude and precipitation in the wettest month had a significant impact on the distribution of Phoebe chekiangensis.The distribution probability of Phoebe chekiangensis increased with the increase of altitude, and it was mainly distributed at altitudes above 400 m.Precipitation also had a great influence on its distribution.The distribution probability first increased and then decreased with the increase of precipitation in the wettest month, and decreased with the increase of precipitation in the driest month.The growth and distribution of Phoebe chekiangensis were jointly affected by various factors such as climate and soil.Conducting dynamic monitoring of the suitable habitats of Phoebe chekiangensis and strengthening ecological protection and management were of great significance for its protection and sustainable utilization.
