Using the method of taking into account the Importance Value(IV) of each species in its vegetation layer in identifying the dominant species or group species in each vegetation layer, this paper classifies the forest communities in Jiangshi area, Fujian Province into 16 associations, belonging to 10 formations and 4 vegetation types. In these associations, there are not only typical evergreen broad leaf forests, but also Torreya jackii forests, which are first discovered in this area, and hard-leaf...

Using the method of taking into account the Importance Value(IV) of each species in its vegetation layer in identifying the dominant species or group species in each vegetation layer, this paper classifies the forest communities in Jiangshi area, Fujian Province into 16 associations, belonging to 10 formations and 4 vegetation types. In these associations, there are not only typical evergreen broad leaf forests, but also Torreya jackii forests, which are first discovered in this area, and hard-leaf oak forests, which are most commonly distributed in high altitude mountainous areas in Southwest China.

本文应用植物所在群落层片中的重要值来确定群落各层的优势种或优势种组的方法,把福建省邵武市将石地区的植被分成4个植被型、7个群系组、10个群系、16个群丛。其中除中亚热带典型常绿阔叶林外,还有以我国珍稀保护树种长叶榧为主所组成的长叶榧林,以及在我国通常仅分布于西南高山地区的硬叶栎类林。 文中对各群系、群丛的组成成份和结构特征进行了较详细的描述与分析,并联系生境特点指出各植被类型的分布及所处立地质量。 最后,作者讨论了将石地区植被的科学与保护及风景价值,建议将本地区列为以长叶榧林、硬叶栎类林等特有生态系统类型为主的自然保护区。

The Gongga Mountainous region is situated in 29°20′—30°00′N. and 101°30′—102°10′E., with its main peak being 7556m above sea level. There are 2500 species of vascular plants belonging to 869 genera and 185 families in Gongga Mountainous region. The main floral characteristics of the Gongga Mountainous region are shown as: the antiquity of the origin of the floristic composition; marked differentiation of species; abundant endemic species; complex composition and obvious geographical replacement phenomenon. The main vegetation types of the Gongga Mountains are: Subalpine conophorium of Abies, Picea; mid-mountain conophorium of Pinus and Tsuga; lowmountain conophorium of Pinus, Cunninghamia, Cupressus, and Keteleeria; mixed wood of conophorium and broad-leaf forest of Tsuga, Acer and Betula; evergreen forest of Cinnamomum, Phoebe, Machilus, Lithocarpus and Cyclobalanopsis; deciduous broad-leaf forest of Quercus, Betula, Acer, Populus and Alnus; hard-leaf evergreen forest of Alpine-Quercus; alpine bush-wood of Rhododendron, Salix and Sabina; river-valley busy-wood of Acacia, Opuntia and Bunhinia; alpine meadow and "rock stream" sparse vegetation of Kobresia, Festuca, Allium, Saussurea, Soroseris, etc.

Quercus aquifoliodes forest is a type of high mountain hard leaf evergreen broad-leaved forests distributing in Hengduanshan Mountain,this paper researches correlation of the minimal areas and the numbers of species inside the minimal areas of Quercus aquifoliodes dwarf forest with altitude gradient at Wolong Nature Reserve in Sichuan Province by the use of Species-area theory.These conclusions indicate that the minimal areas and the numbers of species inside the minimal areas vary regularly with the change of altitude gradient on vascular plants and woody species and grass species respectively,in order to provide some theoretic basis with the researches on high mountain hard leaf evergreen broad-leaved forests.

川滇高山栎矮林是我国横断山区特有的一种高山硬叶常绿阔叶林.应用植物种-面积原理探讨了四川省卧龙自然保区境内的川滇高山栎矮林在海拔梯度上的最小面积与最小面积所含的种数,结果表明:川滇高山栎矮林中草本植物、木本植物和维管植物的种-面积随海拔梯度的变化都各自表现出了一定规律性.此对硬叶常绿阔叶林研究提供了一定的理论基础.
