摘要
对福建九龙江北溪流域的乌冈栎林及建楠、小叶蚊母树灌丛进行了初步研究。它们与典型的干旱植被有一定的联系，属于干旱植被的范畴。在我国东部湿润亚热带地区发生的这种植被是由于局部环境条件的恶劣所致。
The form,Quercus phillyraeoides and form，Machilus oreophila,Distyliumbuxifollus on the north Jiulongjiang River valley were preliminarily investigated.The re-sults shows that both of the formations are related to the typical xerophytia in dry re-gion,It seems that they belong to the catagory of xeromorphic vegetation,In subtropicalregion of East China，xerophytia occurs on drier habitat,
