云南石林碳酸盐岩表面气生藻类群落的研究

A STUDY ON AERIAL ALGAE COMMUNITIES ON THE SURFACE OF CARBONATE ROCK OF THE YUNNAN STONE FOREST

论述了云南石林碳酸盐岩表面气生藻类群落的类型和特征。这些类型包括墨水带、粉末、壳状、膜状等,而每一种藻类群落又是由更细小的次级藻类群落类型组成,它们包括:小型球状藻体群落、大型球状藻体群落、丝状藻体群落、小型球状藻体大型球状藻体群落、小型球状藻体丝状藻体群落等。文中对各类群落和次级群落的特征及它们之间的相关性进行了详细的叙述,揭示了宏观肉眼下气生藻类群落与微观显微镜下藻类群落物种的直接联系以及藻类群落的内部结构和生态关系。该研究对解释石林表面微小形态特征,乃至整个石林景观的形成和演化具有重要意义,同时在气生藻类生态学上也属于新领域。

The well- known Yunnan Stone Forest is located at 24°49′N and 103°19′E, 85km southeast of Kunming , the provincial capital of Yunnan, China. It is not only a great tourist attraction, but also of important scientific and aesthetic value. Yunnan Stone Forest is typical Stone Forest karst landscapes. Black algae communities live on the surface of carbonate rocks there. These black algae communities are mainly aerial cyanobactria communities. The paper discusses the types and characters of aerial cyanobactria communities. The types include ink- strap, powder- like, hull- like and film- like algae etc. An aerial cyanobactria community is composed of smaller secondary aerial cyanobactria communities, types of which include small type spherically frond communities, big spherically frond communities, filament frond communities, small type spherically frond big spherically frond communities, small type spherically frond filament frond communities etc.. The paper discusses in great detail the characters of different types aerial cyanobactria communities and secondary communities as well as their relations. It brings to light that the direct relation between macroscopic aerial cyanobactria communities by naked eye and microscopic cyanobactria species by biologic microscope and the interior structure and ecologic relationship of cyanobactria communities. The study is of great significant to explain the formation and evolution of mini- type and small- type corrosion shapes on the surface of carbonate rock of the Yunnan Stone Forest and even whole Stone Forest landscape. And at the same time, it belongs to a new field in aerial algal ecology.
