摘要
通过分析赤水桫椤自然保护区内植物物种多样性、特有种、植物区系、具有重要保护意义的物种以及其他特色的保护对象,指出赤水桫椤自然保护区植物物种丰富多样,是重要古老木本蕨类桫椤的重要种源库。同时物种和生境的多样性,使得植物群落类型也表现出一定程度的多样性。根据群落发生的不同以及“植物群落学———生态学原则”的划分标准,将该保护区自然植被划分为 5个植被型,人工植被划分为 6种类型,并分别进行了分析。
In this paper, the authors analyse the diversity of the plant species, species endemic, floristic plants, significantly proteced species and other characteristic objects in the Chishui Alsophila spinulosa Nature Reserve, from which it has proved that the plant species are more diverse in the Chishui Alsophila spinulosa Nature Reserve, and it is also an important seed-bank of the ancient woody ptericlophyte Alsophila spinulosa。Meanwhile,it leads to some diversities for the plants community types, because of the diversities of the species and habitats。According to the differences in the community origins and the division standard of the “Plant Community—Ecology Principle”, the natural vegetation in this reserve is divided into 5 types,and artificial vegetation is divided into 6 types, which are explained individually.
