摘要
21世纪以来,随着世界环境恶化和人类活动剧烈,地质灾害呈现频发态势,精密对地观测技术成为其监测预警的重要手段。本文首先介绍了常见地质灾害特点和监测方法,并对InSAR、LiDAR、高分遥感和GNSS 4种技术在地质灾害监测预警中的技术特点及应用进行了阐述,其次对高精度空间监测技术融合进行了综述和展望,最后对未来地质灾害监测预警技术趋势进行了总结。
Since the 21 st century,with the deterioration of the world environment and the intense human activities,geological disasters have been occurred more frequently.Precision space observation technology is an important means for geological disasters monitoring and early warning.In this paper,the characteristics and monitoring methods of common geological disasters are introduced.The technical characteristics and application of InSAR,LiDAR,high resolution remote sensing and GNSS are discussed.The integration of high precision spatial monitoring technology are reviewed and prospected.Finally,the future trends of the geological disaster monitoring and early warning technology are summarized.
