| 摘 要： | 作者根据收集和调查的资料分析得出:宜昌橙分布在我国中亚热带和北亚热带,年均温约18℃以下,绝对低温-15℃以上的地区;中亚热带半湿润区明显的表现出是它分布的边缘区。从宜昌橙的生态地理性结合柑桔属的起源和有关古地理、古气候和古植被分析,推测宜昌橙起源于中新世我国的西南。

| Abstract: | This article gives an analysis of the geographical and ecological distribution of Ichang papeda.The plants of Ichang papeda have a relatively wide distribution in the ever-green,deciduous broad-leaved mixed forest areas in the northern sub-tropical zone,where the absolute low temperature is above -15℃,and evergreen,broad-leaved forest areas in the central sub-tropical zone with yearly average temperature lower than 18℃.Besides the semi-humid areas of the central sub-tropical zone are the periphical region of its distribution. With reference to the origin of Citrus,it is conjectured that Ichang papeda originate in south-west China at Miocene epoch. |
