福建永安石林地貌的现代生物喀斯特侵蚀营力

本文以永安石林为例，阐述分析了石林地貌的现代生物喀斯特侵蚀现象的类型及形态特征。结果表明，地表及地下的生物喀斯特侵蚀营力是石林现代侵蚀过程的主要因素，石林表面的大部分均有微生物覆盖并起侵蚀作用，形成明显的微观及超微溶蚀形态，石林表面的溶蚀作用性质不同于传统认识。对石林地貌发育提出了新的思考。

ON MODERN BIOKARST EROSION ON YONGAN STONE PINACLES,FUJIAN PROVINCE

Based on both field and laboratory observations on erosion features of Yongan Stone Pina-cles,Fujian Province,the morphlolgic characteristics and the types of modern biokarst erosionwere elucluated and analytal in the paper.It is concluded that both surface and subsoil biokarsterosion agents are main causes for medern erosional processes of the stone pinacles,As it is foundthat there is organic coating by micrcorganisms on most part of surface of stone pinacle withrelated obvious erosional fcatures in micro or ultral scale,it suggests that surface erosional agentof stone pinacles should be mu ch larger than that of traditional estimation.
