摘　　要：喀斯特石漠化是自然与社会,经济综合作用的产物,是岩溶山区实现可持续发展的主要屏障因素。石漠化造成土地资源丧失、生态系统退化。近年来对于石漠化的治理工作取得明显的效用。但是对于石漠化治理区域的监测目前大多处于人工调查的阶段,不能快速的做出评价、管理及决策,急需改用监测方式,提高效率。本文以普安县地泗河流域为研究样区,应用中高分辨率遥感影像对石漠化治理工程进行监测。应用遥感影像监督分类及人机交互解译提取研究区域的工程建设信息。并结合GPS现场验证监测结果。研究结果表明该方法能够快速有效的对石漠化治理工程进行监测,有较大的推广实用价值。Karst Rocky Desertification （KRD） is the comprehensive result of nature, social and economy. Meanwhile, it hinders the sustainable development in Karst mountainous regions. KRD can result in loss of land resources and degradation of ecosystem. In recent years there has been obvious effect on the control work of KRD. However, the KRD control monitoring has still been in the period of manual investigation. Therefore, it can not estimate, manage and make decisions rapidly. This paper aimed to improve the monitoring methods and increase the working efficiency, selected Disi Basin of Puan County as the study area and used medium-high spatial resolution Remote Sensing （RS） images to monitor the KRD control projects. The project construction information of the study area was obtained using supervised classification and human-computer interactive interpretation and the monitoring results were testified with GPS. The results showed that this method could rapidly and effectively monitor the KRD control projects.
