摘要(Abstract)：

利用Diva-Gis软件对西南地区香椿(Toona sinensis)的潜在地理分布区及其气候特点进行分析。结果表明,西南地区香椿分布在海拔200 m~2 900 m之间,分布的植被类型主要为针阔混交林、阔叶林、人工纯林和农田防护林。西南地区适宜香椿生长的年均气温为11.7℃~22.8℃,年降雨量为752.0 mm~1 490.0 mm。香椿的分布区与潜在分布区主要在四川盆地及盆周,云南、重庆及贵州的中低山地区、西藏察隅和波密县。在气候变暖的趋势下,香椿的潜在最适宜分布区面积减少,呈现破碎化分布,向高海拔地区和西北方迁移。
The potential geographic distribution areas of Toona sinensis in southwestern China regions and their climate characteristics were analyzed based on DIVA-GIS. The analysis results showed that the distribution elevation of T. sinensis ranged from 200 m to 2 900 m and T. sinensis trees were distributed in broad-leaved and needle leaved mixed forest,broad-leaved forest,planted forests and farm-shelter forest.The suitable mean annual temperature and annual precipitation for the growth of T. sinensis were 11. 7℃~ 22. 8℃ and 752. 0 mm ~ 1 490. 0 mm,respectively. The geographical distribution and the potential regions of high suitability for T. sinensis were the Sichuan basin and its surroundings,the hill and low mountain regions in Yunnan,Chongqing and Guizhou,and Chayu and Bomi counties of Tibet. The global warming might lead to the shrinking in its suitable regions and it might have a tendency of shifting to high-altitude and northwestern regions.
