摘要： 通过对我国及国外典型喀斯特区域的样品观察,本文对内陆及海岸灰岩表面藻类的分布、对基岩的作用类型和机制以及在喀斯特地貌侵蚀形态发育过程中的作用进行了初步的分析和探讨,所有结果表明,藻类作用十分普遍并在尺度上具有层次性,在微观尺度上形成了独特形态,藻类的侵蚀机制有化学和机械之分,最基本的过程为钻孔作用。

关键词: 喀斯特侵蚀, 藻类作用, 微形态

Abstract: Since the beginning of the study on "phytokarst"(Folk et al，1973)，more and more atten- lion has been paid to algal effects on the karst erosional processes，Having optical microscope (OPM)and scanning electronic microscope (SEM)observations on the micro一relieves of samples from typical karst areas in China ,Yugoslavia and England .a more detailed discussion on the algal effects on karst erosion is given in this paper.

Key words: Karst erosion, Algal effects, Micro一morphology
