| 利用Diva-GIS 软件分析短序润楠（Machilus breviflora）的适生区，并用BIOCLIM 生态模型评
估未来潜在分布区对气候变暖的响应。短序润楠分布在我国南亚热带及热带的中低山地区，水平分布范围
为18°73′～30°66′N、104°02′～115°24′E，垂直分布在海拔200～1600 m；短序润楠分布于常绿阔叶林
及常绿针阔叶混交林植被类型中；广东地区为短序润楠的现在分布中心，在279 份有效标本记录中有231
份来自广东，约占82.8%；短序润楠的潜在分布区为粤、桂、琼、港、赣、湘、闽、川及黔等省份；在未来气
候变暖的影响下，短序润楠的适生范围略有扩大，潜在分布区往北适当扩展，但是最适分布区显著减少，且
最适分布区连续性变小。研究结果对现有短序润楠野生资源的保护、扩大引种造林和园林应用有一定的理
论意义和实践指导价值。 |
| 英文摘要: |
| The geographical distribution of Machilus breviflora in China was analyzed based on DIVA-GIS，
and the response of future potential distribution to global warming was estimated by Bioclim model．M. breviflora
was distributed in the low to medium altitude from 200 m to 1 600 m mountain forests of south subtropical and
tropical zone of China，which was 18°73′-30°66′N，104°02′-115°24′E. The distribution of vegetation types
is evergreen broad-leaved forest and evergreen coniferous broad-leaved mixed forest. Guangdong province is the
modern distribution center of M. breviflora，in 279 valid samples，231 samples were from Guangdong，accounting
for about 82.8%. Potential distribution estimation indicated that Guangdong，Guangxi，Hainan，Jiangxi，Hunan，
Fujian and Hong Kong，Sichuan and Guizhou were the optimum places for M. breviflora to survive. The model
simulation indicated that the suitable habitats would initially increase under the climate change scenarios，whereas
the marginally suitable habitats would have a relatively small change. The results could provide valuable references
for the wildlife protecting，introduction and landscape application of M. breviflora. |
