| 摘 要： | 水青冈属(Fagus)植物是北温带落叶阔叶林的主要树种,该属共有11种。中国5种均为特有种。本文着重分析了中国5种水青冈——水青冈(Fagus longipetiolata)、米心水青冈(F.engleriana)、亮叶水青冈(F.lucida)、台湾水青冈(F.hayatae)和平武水青冈(E.chie-nii)的分布与最冷月平均温度、最热月平均温度、温暖指数[WI=∑(t—5)]、寒冷指数[CI=—∑(5—t)和生长季(4—10月)的降水量等5项气候指标的关系。结果表明:限制分布的主要气候因子是生长季和降水量,喜马拉雅运动、冰后期气候的改变以及人类的干扰也促使分布区收缩。 |

| Abstract: | There are 11 species in Fagus,5 of them are endemic to China.They are the major trees of deciduous broadleaved forest in Northern temperate region.This paper mainly deals with the relationship between the distribution of 5 species and 5 climatic indices.The results showed that the principal factor controlling the distribution of Fagus was the precipitation in grow- ins season.The climatic change which resulted from Himalayan movement and the changes during post-glacial period and human disturbance also affect the contraction of the range of distribution. |
