摘　　要：据长期对岩溶及红土化作用等的研究成果 ,本文全面系统地分析了碳酸盐岩上覆红土的形成及演化规律 ,提出了一个新的碳酸盐岩上覆红土的形成模式 ,进而深入阐明了碳酸盐岩上覆红土的演化规律及其在现代气候条件下的演化趋势等 ,在解决岩溶及红土学术界存在的碳酸盐岩上覆红土的形成、碳酸盐岩与上覆红土之间的相互关系及其发展演化规律等一系列重大疑难问题上向前迈进了一步 ,对相关学科的发展将产生积极的推动作用。The process of forming and evolution of laterite on the surface of limestone were analyzed systematically and comprehensively in this paper according to our long-term work about karst and laterization. A new forming model for the laterite overlying the surface of carbonate rocks was represented, and based on it, the evolutional rules and evolutional trends, under the modern climate condition, were discussed further. As a result, to solve some difficult academic problems in the field of karstification and laterization, including forming and evolution of the laterite overlying carbonate rocks, the relationship between the carbonate rocks and their overlying laterites, made a good progress. In addition, it might promote development of related scientific branches.
