摘要
本文着重从地质和生态的角度,阐述喀斯特石漠化的形成特点和演化方式及其对综合治理的指导意义。对西南岩溶山地而言,土壤和植被是生态环境中最为敏感的自然环境要素,与非岩溶区相比,具有明显的脆弱特征。它们在干扰下发生迅速演替,诱发地表水文条件的改变,导致石漠化的形成。文中特别强调岩溶山区碳酸盐岩基底岩性的不同、生态环境类型与植被演替的方式和进程的多样性对于岩溶生态系统的影响作用。基于上述认识,对石漠化地区的土地利用方式和生态恢复过程以及可能发展的方向提出了一些建议和看法。
From the geological and ecological point of view, the author discussed the formation and succession characteristics of Karst rock desertification. The soil and the vegetation are the most sensitive natural components for the southwest Karst mountain areas, thus showing a evidently fragile characteristics compared with the non - Karst areas. It was emphasized in this paper that the different types of carbonatite base rocks and the diverse ecological environments and succession models have an influence on the Karst eco - system. Based on the above recognition, the author proposed some suggestions and ideas for the ecological restoration of the Karst areas.
