Abstract: Landslide disaster is one of the natural disasters with the highest frequency, largest distribution, and highest losses worldwide, endangering human life and property as well as important engineering facilities. Scientific monitoring is one of the most significant measures for monitoring and early warning of landslide, as well as active prevention. Landslide monitoring has gradually evolved from traditional manual ground monitoring on specific site to multi-dimensional collaborative monitoring after years of technical research and integration of high-resolution optical remote sensing, satellite InSAR, UAV photogrammetry, wireless sensor network (WSN), and other new technology methods, allowing China to achieve remarkable results in geological disaster risk identification, monitoring, and early warning. Based on a professional understanding of the landslide occurrence mechanism and deformation damage process, this paper summarizes the most recent research progress in landslide monitoring technology in China from the three-dimensional perspectives of spaceborne (optical remote sensing and InSAR), airborne (UAV photogrammetry), and ground-based (global satellite navigation system, crack-meter, and other ground surface and internal monitoring of slope), analyzes, and discusses the technical advantages and disadvantages. The technical advantages and applicability of each in engineering practice are analyzed and discussed, and a new cooperative monitoring mode for the entire process of landslide deformation and damage is proposed, providing a new paradigm of thinking and experience guidance for the scientific prevention of landslide disasters.
