中文摘要	考虑到地表石漠化的复杂性,借鉴林业部门的石漠化状况与程度评定方法,充分利用地理国情地表覆盖与DEM成果,结合遥感监测技术,计算地表的基岩裸露度与植被综合盖度,以野外实地调查为佐证,获取研究区域石漠化监测评定因子,确定研究区域石漠化的状况与程度,构建一套基于遥感解译的石漠化监测技术方法。结果表明,研究区自20082016年,石漠化发生率明显下降,区域生态环境逐步恢复;本文研究的技术方法可行,在节约人力资源的基础上,可快速获取石漠化状况与程度。
英文摘要	Considering the complexity of the surface rocky desertification,drawing on the evaluation methods of the state and degree of the rocky desertification of the forestry department,making full use of the results of the geographical conditions of the land surface coverage and DEM,combining with the remote sensing monitoring technology to calculate the comprehensive coverage of the bedrock and vegetation on the surface,taking the field investigation as the evidence,obtaining the monitoring and evaluation factors of the rocky desertification in the study area,and determining the state and degree of the rocky desertification in the study area,a set of rock desertification monitoring technology is constructed based on remote sensing interpretation. The results show that from 2008 to 2016,the occurrence rate of rocky desertification in the study area has decreased significantly,and the regional ecological environment has been gradually restored. The technical methods of this study are feasible,and on the basis of saving human resources,the status and degree of rocky desertification can be quickly obtained.
