| 摘 要： | 广西岩溶区生态地质环境脆弱，石漠化明显，面积达27294．5km^2，严重地制约着地区的经济发展。广泛分布的纯碳酸岩是形成石漠化的基础，地貌植被退化过程也可促进石漠化。水和气候也是石漠化形成的重要条件。人口增长过快、不合理的土地开发、工业污染是形成石漠化的重要因素。但自然因素和人为因素的主次因地而异。文中针对石漠化的形成条件及原因，提出了治理对策，阐述了石漠化的治理需要采用治水、恢复生态环境、发展沼气、控制人口增长等综合治理模式。

| Abstract: | Fragile and weak ecological geology and severe stony desertification reaching27294.5 square meters in Karst area has hindered local economic development of Guangxi. Widespread distributed pure carbonate rock is the basis on which stony desertification formed while relief and vegetation retrogression process can also promote desertification. Besides, water and climate are also important conditions to form desertification. Rapid population growth, unreasonable land development and industrious pollution all compose important factors which promote desertification. But the importance places. The harness countermeasures were proposed of natural factors and artificial factors vary in aimed at forming conditions and causes of desertification. It is pointed out that desertification harnessing requires comprehensive harnessing model involve water management, ecological environment recovery, firedamp development and population growrh control etc. |
