| Abstract: |
| 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. |
