摘要
喀斯特环境中地表水土过程对表层喀斯特过程具有重要意义。在石林区域的地质环境变化条件下,石林形成是从剥蚀夷平期的厚层红土覆盖环境下的石芽溶蚀发育,至厚层覆土受侵蚀后出露深大石芽,再至现代石林的多重侵蚀改造的宏观演变过程。与地表水土过程有关的的风化壳覆盖溶蚀机制与揭露侵蚀机制是石林发育演变中的两个关键机制。
karst soil has driving meaning to epikarst delvelopment as one important factor in the topographic environmental process. Taking case of Shilin,Shilin formation showed the development process of Shilin evolution from the embeded rock peak with deep soil coverage during denudation- planation period to exposed high and deep rock peak for the cause of soil erosion and then to multi- fractal erosion and reform of modern stone forest. The combined surface process in development of soil and soil erosion formed two key mechanismes as sub-soil disslution mechanism under the weathering shell sand the exposed erosion mechanism on the background of geological environmen changes.
