摘　　要：介绍石漠化的概念、特点、主要成因及其危害,结合广西喀斯特岩溶地区的实际情况,指出人口过度增长、经济落后、人地矛盾加剧以及不合理的人为活动是造成石漠化的主要根源,植被破坏是石漠化产生的直接诱因,具体分析了广西喀斯特岩溶地区石灰岩植被遭受人为破坏而产生石漠化的过程,还介绍了广西石漠化治理工作的一些成功经验和生态恢复模式,为其他地区的石漠化治理提供参考和借鉴。The concept,characteristics,main causes and impacts of karst deserfification (KD)are introduced. Based on an investigation of karst areas in Guangxi Zhuang Autonomous Region,the root causes of KD include rapid population increase,poor local economy,human and land conflict,unsustainable human activity such as deforestation,steep slope farming,and pollution.It is pointed out that the clearing of vegetation is a direct contributor to KD.The process of KD caused by destruction of limestone forest vegetation is analysed in detail.In order to provide some reference of KD control for other region,some successful experiences of karst eco-restoration in Guangxi are introduced.
