摘要
太白山3400米以上的高山地区,冰期曾经过强烈的冰蚀作用。覆冰退却之后为光秃的裸岩。本文仅对该冰蚀原生裸地植被的起源、演替及发展趋向作初步探讨。1.微生植物群落阶段:我们在不同地点裸岩表面上,采取既无地衣、又无苔藓及其它任何非微观植物定居的裸岩标本二十份,进行了培养和鉴定。
The vegetation evolution of the ice-eroded primordial soil started from microorganism community consisting of bacteria and algae passed through lichen community,moss community and Kobresia grassland,and finally reached the stage of Rhododendron fastigiatum and Salix cupularis bushes.The fundamental driving force of the evolution is generated from an edaphological endodynamic force under the reaction of plant communities.
