广西石灰岩地区蕨类植物的生态效益初探

对广西石灰岩地区蕨类植物的生态效益进行了多方面的分析。由于其物种性状间的差异，表现出了对各类不同小环境的极强的适应世，加上不同种类的形态和生长习性之间具有着很多的变化和明显的差异，因而构成在空间分布格局上有很大变化，也形成了不同的景观类型。因此，蕨类植物在石灰岩地区对于植物群落的建成、水土的保持、大气湿度的调节、温度的调节和景观格局的构成等方面具有着重要的作用。进而对石灰岩地区良好的人居环境和农业生态环境的建立和维护、对于丰富当地的生物多样性等方面具有相当重要的意义。

A Preliminary Study on the Ecological Benefit of Fern in Limestone Area of Guangxi

The ecological benefit of ferns in limestone region of Guangxi have been studied inpresent paper. Because of differences in adaptability, properties, such as morphology, growthhabits, ferns have many distribution patterns in space and form the different landscape type. So theferns take a very important part in building up of plant community, keeping of water and soil, adjusting of atmosphere humidity, adjusting of temperature and forming of landscape pattern. Fernsare very important for the establishment of nice environment to living and agricultural ecology, andfor the enrichment of local biodiversity-
