摘要:
 采用MaxEnt模型、ENM Tools、R语言和地理信息系统（ArcGis）相结合的方法，预测天女木兰在我国的适生区域，确定影响天女木兰地理分布的主导环境因子。结果表明，预测的天女木兰高适生区主要分为2个主要区域：一个位于东北地区的吉林省南部与辽宁省中东部组成的带状适生分布区；另一个由华东和华中地区的安徽省南部、浙江省西部、江西省中东部与福建省北部等地区组成不均匀的团块适生分布区。天女木兰在我国的高、中和低适生区面积分别为21.96、52.41×104 km2和155.627×104 km2；年均温较差和最湿季度降水量环境变量在预测天女木兰在我国的地理分布中起着主导作用，为我国天女木兰迁地保护引种地的选择与科学保育提供依据。
Abstract:
 Using a combination of the MaxEnt model,ENM Tools,R language and the ArcGIS,this study predicted the suitable distribution regions for Magnolia sieboldii in China,determined the dominant environmental factors affecting the geographical distribution of M.sieboldii.The results showed that the predicted high suitable area of M.sieboldii were divided into two main regions,one was the belt-form suitable distribution region,which was composed of the southern part of Jilin Province and the middle and eastern part of Liaoning Province in northeast of China,and the other one was composed of southern Anhui Province,western Zhejiang Province,central and eastern Jiangxi Province and northern Fujian Province in eastern and central China.The high,medium and low suitable areas were 21.96,52.41×104 km2 and 155.627×104 km2,respectively.The environmental variables of average annual temperature and precipitation in the wettest season played leading roles in predicting the geographical distribution,which provided a basis for the selection of introduction sites and scientific conservation of M.sieboldii in China.
