Assessing the susceptibility of slope geological hazards based on multi-source heterogeneous data: A case study of Longgang District, Shenzhen City

This study aims to investigate the fundamental facts concerning slope geological hazards in Longgang District, Shenzhen City, as well as the distributions of disaster-prone zones in the district. Based on the multi-source remote sensing satellite data, this study interpreted the slope geological hazards using the expert interpretation method on a geological hazard interpretation platform. Furthermore, some interpreted geological hazards were verified through field verification combined with Baidu Street View data. Finally, the distributions of zones susceptible to slope geological hazards in Longgang District were determined using the information value method, with the slope height, slope gradient, rainfall, surface lithology, and land cover as assessment factors. Additionally, existing geological hazard sites were superimposed with the susceptibility assessment results for analysis, yielding completely consistent results. This confirms the effectiveness of the method used in this study for assessing the susceptibility of slope geological hazards, as well as the accuracy of remote sensing interpretation of slope geological hazards.
