新疆科古琴山高山流石坡植被的特征

The characteristics of vegetation of rock-flowing hillside of high mountains on Mountain Keguqin in Xinjiang

研究对新疆科古琴山高山流石坡植被的植物区系特点、植物群落特征和生物—生态学特性进行了论述。初步查明该地有种子植物 1 7科 2 7属 34种、藓类 5种、地衣 9种。说明该地种子植物种类贫乏 ,特有种少 ,植物区系成分年轻 ,温带特点突出。植物生长稀疏 ,盖度小 ,植物群落结构简单、层次分化不明显、季相单调。植被因坡度、坡向的不同存在明显差异。其植物具有株矮、叶小、根系发达、丛生、莲座状、体被茸毛、生长期短、以营养繁殖为主、多年生、耐寒等特性。

In this paper,the result of a study on floristics characteristics,plant community and biology ecology features of vegetation growing along rock flowing hillside of high mountains on Mountain Keguqin in Xinjiang is provided.Till now 17 families,27 genera and 34 species of seed plants,5 species of lichenes and 9 species of bryophyta are found in this area.The flora consists of few plant species (including some fewer endemic palnt species) which are young and prominently showing temperate character.Growing sparsely with little coverage,the plant community shows simple structure,indefinite synusiae differences and dull aspect.Some obvious differences exist among plants due to different inclination exposure.The plants on rock flowing hillside of high mountains have many adaptabilities.They have short bodies,microphyllies,strong root systems and rosella shapes.They are cespitose,pappose,perennial and mainly of vegetative propagation.They are coldresistant and have short growth periods also.More methods should be taken to protect the vegetation including some valuable wild medical plant resources of rock flowing hillside of high mountains.
