中文摘要	综述了关于喀斯特石漠化分类和程度分级的各类研究,分别讨论了其中最具代表性的观点和方法。在石漠化概念的一些典型观点基础上,分析了喀斯特石漠化的3个判定条件,认为尺度的确立应当作为石漠化评价的先决条件,景观指标是程度分级的必要非充分条件。成因分类和外部特征分类是石漠化分类必不可少的依据,两者相互补充才能构成完整的分类体系。喀斯特石漠化概念、尺度、分类、程度分级之间有着内在的逻辑关系,先分类后分级是正确的石漠化评价方式。笔者依据岩性、土地利用类型以及石漠化程度提出一种新的分类思路,即内因+外因+现状3层分类系统。
英文摘要	This paper summarized various researches on the classification and degree classification of Karst rocky desertification, and then discussed the most representative viewpoints and methods separately. Three determination conditions were analyzed based on a series of typical viewpoints. This paper suggested that scale should be a prerequisite for rocky desertification evaluation. Landscape index was not the sufficient condition to degree classification but the necessary condition. Classification according to causes and external features were both essential to rocky desertification,as long as they complement each other we would form a complete classification system. There were inherent logical relationships among karst rocky desertification concept, scale, classification and degree classification. Grading followed up classification, and this was the correct order for rocky desertification evaluation. According to lithology, land use types and the degree of karst rocky desertification, it comed up with a new proposal of classification which was a three layers classification system: internal cause+external causes+status.
