Abstract: In recent years, China has obtained mass of research results in the monitoring of landslides, but there are still some problems that have not been solved. Taking CNKI as the source of data, academic papers in the field of landslide monitoring have been statistically analyzed, and the visualization software of the literature was used to dig and analyze the main researchers, research hot spot and evolution vein of the field. The existing monitoring technology has been summarized from three aspects of ‘space, sky, and ground’. In addition, the development and application status and research trends of landslide monitoring technology have been explained in detail. Finally, the key problems and countermeasures in the field of landslide monitoring were pointed out. The results showed that the publication in landslides monitoring has been rising in stages. The development and innovation of monitoring technology and the research on landslide forecasting and early warning were the hot research topics in this field. XU Qiang, YIN Kunlong and YI Qinglin, these three professors, and their teams gathered the core research forces in the field. There were many landslide monitoring technologies based on ‘space, sky, and ground’, they had their own advantages and disadvantages. It was difficult to obtain ideal results through a single method, only by comprehensively using multiple technical means can we obtain a deeper understanding on the evolution of landslides. At present, monitoring technology is being transformed towards the improvement of forecasting and early warning capabilities, and building a multi-dimensional, accurate, dynamic, visible, remote monitoring and early warning platform will become a major direction of intelligent and high-quality development in the field of disaster prevention.
