温州壳斗科植物的种类组成与分布特点

Species composition and distribution characteristics of Fagaceae plants in Wenzhou

在野外调查、文献和标本查阅的基础上,对温州地区野生的壳斗科植物进行了全面的分类整理,探讨了其种类组成和分布特点。现知温州市有壳斗科植物6属36种,占浙江省种数的81.82%,是浙江省壳斗科种类最丰富的地区。温州的36种壳斗科植物可分为广布种7种、常见种14种、偶见种9种和稀有种6种。温州市各县(区、市)拥有的物种数差异较大,山区明显多于东部平原和海岛,其中最多的是泰顺,有34种,最少的是洞头,仅有4种。温州壳斗科植物分布格局的形成不仅与各属种的区系性质和生态适应性有关,也受温州各地的地形地貌、海拔高度及人类活动的影响。并对已列入浙江省重点保护野生植物名录的卷斗青冈和刺叶栎的稀有原因进行了分析,提出了保护建议。

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.
