摘　　要：岩溶地貌在全球广泛分布,造就了丰富多彩的地貌形态及自然景观。在我国湘黔鄂渝交界区存在着极具观赏性的特殊岩溶地貌,其形态特征有别于常见的岩溶地貌。但当前对这套特殊岩溶地貌的名称及其地学价值尚未深入探讨。该类型地貌具有四个基本特点:红颜色、层状凹凸形态、泥质灰岩的成景岩性、土下环境差异溶蚀成因。在对比分析它与红色系地貌、已认识的岩溶形态、常见岩溶地貌的差异性基础上,文章采用“外观特征”+“地貌类型”的命名原则将它命名为“红色层状凹凸岩溶地貌”,简称“红色岩溶”,并提出其科学定义及界定标准。红色岩溶具有重要的地学价值,其极具观赏性的独一无二形态使得红色岩溶具有重要的旅游经济价值。Karst landforms are widely distributed throughout the world,creating a variety of terrains and natural land⁃scapes.In the border areas between Hunan,Guizhou,and Hubei provinces and Chongqing City,China,There exist spe⁃cial ornamental karst landforms,of which the morphological characteristics are different from common karst landforms.However,the name of this special karst landform and its geological value have not been thoroughly explored so far.It has four basic characteristics,red color,layered concave-convex morphology,lithology of argillaceous limestone,and genesis of differential dissolution in soils.In contrasting the differences between it and the red series morphology,known karst morphology,and common karst landforms,this paper uses the naming principle of"appearance character⁃istics"+"landform types"to call it as"red layered concave-convex karst landform","red karst"in short.Also,its sci⁃entific definition and criteria are proposed.The red karst has important geological value in geosciences and tourist eco⁃nomic value due to its unique ornamental form.

关 键 词：红色岩溶 岩溶地貌 凹凸形态 土下差异溶蚀
