| 摘 要： | 喀斯特石漠化蚕食区域土地资源，制约当地经济的可持续发展，受到国内外学者和政府的广泛关注。鉴于石漠化防治的长期性和艰巨性，梳理有关石漠化在国际上发表论文的相关研究进展，分析当前发展态势及研究前沿和热点，可为石漠化的治理与恢复提供支撑。本文以“Web of ScienceTM核心合集”为主要数据库，检索获取关于石漠化的英文发表成果。利用CiteSpace文献分析工具，进行石漠化研究进展的可视化表达和分析。结果显示:①对比全球的碳酸盐岩区域和人口分布发现，尽管石漠化在多国都有分布，但剧烈的人为扰动导致石漠化在中国西南岩溶地区最为突出；②中国在石漠化研究处于领先地位，国际上发文量最大，发文数大致经历了起步-缓增-稳增-快增的发展过程，中国学者研究与政府投入密切相关；③以贵州省为代表的中国西南地区是发文的核心区，石漠化监测与治理及其对生态环境影响是当前研究的热点和难点。文章综述喀斯特自然环境和人类活动及其交互效应对石漠化演替的影响过程，阐明了石漠化正逆演替过程造成的生态环境效应。综合已发表文献，指出未来需要从高精度石漠化自动制图技术、石漠化与人为活动互馈机制和石漠化恢复与生态环境提升协同路径等3个方面深入研究。

| Abstract: | The Karst Rocky Desertification（KRD）encroaches the regional land resources and limits the sustainable development，which has received extensive attention from scholars and governments at home and abroad. Considering the long-term and arduous nature of the prevention and control of KRD，it is benefical to support the control and restoration of KRD by sorting out the relevant international progress on KRD and analyzing the research trend and frontier hotspot of KRD. Based on the database of Web of Science TM Core Collection，this study retrieved and collected the internationally published references of KRD research. The CiteSpace，a reference analysis tool，was used to visual express and analyze the KRD research. Results showed that，（1） Comparing the global carbonate rock and population distribution ，it is found that the carbonate rock outcrops are widely distributed in the world and the KRD was found in various countries. However，the intense human disturbance has resulted in the serious KRD in the southwest China；（2） China is in the leading position in the scentific studies of KRD and has the largest volume of publications in the world.The number of publication has undergone a development process of early development-slow growth-steady growth-rapid growth ，which is closely related to the research of Chinese scholars and government investment； （3）The southwest part of China，typically represented by Guizhou Province，is the core research region for publications. The monitoring and control of KRD and its ecological and environmental impacts are current hotspot and difficulties . This paper reviewed the effects of karst natural environment and human activities and their interactions on the succession of KRD， as well as clarified the ecological and environmental effects caused by the progressive succession and retrogressive sucession of KRD. Based on the published papers，three future aspects were suggested to be deeply studied: high-precision automatic mapping technology of KRD，mutual feedback mechanism between KRD and human activities，synergy path between KRD restoration and eco-environment improvement. |
