<正>福建柏属植物约起源于晚侏罗纪,起源中心在东亚环太平洋地区,第四纪冰期后仅福建柏1种残存中国南方和越南北方,形成残遗中心。据史料分析,福建柏历史上分布较现代广泛,自中国东部福建沿海至云贵高原东南部沿南岭山脉纬度一线基本呈连续分布。现代中心分布区在东经110°～119°,北纬24°30′～26°30′,呈间断分布;垂直分布海拔500～1800m,往西、往北分布海拔较高,往东、往南分布海拔较低;分布区属中亚热带湿润气候。福建柏为浅根性树种,树冠承雪量大,易遭大风和冰冻危害,成为其向高海拔地区发展的限制因素。

Fokienia originated from East Asia in late Jurassic.After fourth glacier,only F.hodginsii as a relict survied in south China and north vietnam,where is considered as relic centre.According the analysis of historical data,F.hodginsii distributed wider in the ancientry than modern times.The area is from Fujian coastal east to the southeast of plateau of Yunnan and Guizhou,basically a long Nanling Mountains range latitude in succession.The modern distribution centre area is 110°～119° E,24°30′～26°30′ N,and not concatenation.F.hodginsii distributed apeak 500～1?000?m in altitude.In generally,it distributed in a higher altitute in west and north than in east and south.The distribution area is subtropic warm-moist climate.F.hodginsii is not a deep root plant,and the crown of a tree holds a lot of snow in winter,so it is very easy to be damaged by strong wind and heavy snow,which is the restricted factor towards the high altitude.
