摘　　要：目前中国逐渐从土壤发生分类过渡到系统分类,与同地带其他土壤相比,石灰岩土壤由于其本身发育的特异性,在系统分类中需衡量的属性更为复杂。笔者总结分析中国南方石灰岩土壤发育特性,综述其主要诊断层和诊断特性,提出未来南方石灰岩土壤分类需进一步加深了解石灰岩地区地质演变及生态环境过程,运用多技术综合分类对比检索、检验土壤分类系统。同时,由于岩溶区"人多土少",土地利用强度较大,尤其应加强人为土诊断特性和现象的精细辨识,最终为推动石灰岩土壤的系统分类研究和岩溶生态系统土壤可持续利用提供理论基础。At present, China is in the transition period from soil genetic classification to genealogical classification, compared with other zonal soil, limestone soil has more complex properties due to its specialgenetic characteristics in classification. The authors analyzed the genetic characteristics of limestone soil inSouth China, summarized its main diagnostic horizon and diagnostic characteristics, put forward that in theclassification of limestone soil in South China, geologic evolution and ecological environment should be furtherunderstood, and the multi- technology comprehensive classification to contrast and check soil classificationsystem should be adopted. In the same time, due to the characteristics of＂few soil with large population＂andhigh land use intensity in karst area, the elaborate identifying of diagnostic characteristics and phenomenon ofanthrosols should be strengthened, to promote the study on genealogical classification of limestone soil and provide reference for the sustainable utilization of karst ecosystem soil.
