Abstract: In order to discuss the species composition and distribution characteristics of the wild Fagaceae plants in Wenzhou， the taxa of Fagaceae collected from Wenzhou were overall sorted based on the literature consulting， field investigation and specimens examination and identification. The results showed that 6 genera and 36 species of Fagaceae， which account for 8182% of the total species of Fagaceae in Zhejiang， were recognized in Wenzhou， so that Wenzhou owns the highest species diversity and richness of Fagaceae in Zhejiang. The species quantities of Fagaceae in different regions of Wenzhou were various， which in mountainous areas were significantly greater than the eastern plains and islands. The 36 species can be divided into 7 cosmopolitan species， 14 common species， 9 occasional species and 6 rare species. And Taishun County has the most species （34 species）， with Dongtou County owning the least species （4 species）. The distribution pattern of the plants of Fagaceae in Wenzhou is not only related to the floristic features and ecological adaptability of different species， but also related to the local topograhy， altitude， and the impacts of human activities. The endangering factors to Cyclobalanopsis pachyloma and Quercus spinosa which are listed as the key protected wild plants in Zhejiang were analyzed， and the corresponding protection proposals were proposed.
