[目的]探讨影响濒危植物银杉(Cathaya argyrophylla)种群发生的关键因子及预测其在当前与未来的潜在分布区,为银杉天然种质资源的保护和引种栽培提供理论依据.[方法]基于银杉的 41 个样本点,结合气候、地形、土壤、辐射因子数据,采用MaxEnt模型预测当前情景下银杉的潜在分布区,评估不同环境因子对银杉地理分布的影响,同时以未来共享社会经济数据(SSPs)作为气候数据,预测银杉未来的潜在分布区.[结果]当前气候条件下,银杉核心适生区面积约为 1.325×105 km2,约占我国国土面积的 1.38%;最干月份降水量、下行紫外线辐射、海拔、最冷月份最低温度对银杉分布影响的累计贡献率为 91.9%,是影响银杉地理分...

[Objective]This study explored key factors affecting the occurrence of endangered Cathaya argyrophylla populations and predicted their potential distribution areas in the present and future,providing a theoretical basis for the conservation and introduction of C.argyrophylla natural resources.[Method]Based on 41 sample sites of C.argyrophylla,the MaxEnt model was used to predict the potential distribution areas of C.argyrophylla under the current scenario by combining climate,topography,soil and radiation factor data,and to assess the effects o...
