摘　　要：为揭示气候变化对浙江楠(Phoebe chekiangensis)适生区的影响,利用生态位模型和气候数据,共选择12个变量(分别为海拔、最湿月降水量、最干月降水量、土壤厚度、最湿季平均气温、等温性、坡向、坡度、气温年较差、最冷月最低气温、平均气温日较差、最干季降水量),系统地研究浙江楠在浙江省的适生区分布及其变化规律。结果表明,平均AUC值为0.858,标准偏差为0.042,说明预测具有较高的可信性。浙江楠的适生区(适生值>0.05)总面积为5.27万km^(2),其中高适生区、中适生区、低适生区面积分别为0.74、1.50、3.03万km^(2);丽水、衢州大部分地区、金华南部山区和温州西南山区等适合浙江楠生长发育。海拔和最湿月降水量对浙江楠分布有重要影响,浙江楠分布概率随海拔的增加而增加,主要分布在海拔400 m以上;降水量对浙江楠的分布有较大影响,分布概率随最湿月降水量的增长先增加后降低,随最干月降水量的增加而降低。浙江楠的生长与分布受气候与土壤等多种因素共同影响,开展浙江楠适生区的动态监测,加强生态保护和管理,对于其保护和可持续利用具有重要意义。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 km^(2),among which the areas of the highly suitable,moderately suitable,and low-suitable habitats were 7400 km^(2),15000 km^(2),and 30300 km^(2) 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 protect
