结合历史文献，对中国柑橘栽培地理北界的变化进行了探讨。南北朝末年和明末，柑橘种植超过了现在的北方地理边界，而在其他一些时期，柑橘种植出现了明显的南移。这主要与气候变化有关。清初比较详细的记载表明，在以连年寒流为特征的气候中变冷的倾向，对中国柑橘种植北界的确定起到了决定性作用。
In light of historical documents,the writer explores the changes in the geographic northern bounds of China’s orange cultivation.In the late Northern and Southern Dynasties and the late Ming Dynasty,orange cultivation exceeded its present northern geographical bounds,while in some other periods,such bounds displayed obvious recession to the south.All this is chiefly related to climatic changes.Comparatively detailed records in the early Qing Dynasty indicate that the tendency to become cold in the climate characterized by successive cold spells played a decisive part in setting the northern bounds of China’s orange cultivation.
