Current and Future Status of GIS-based Landslide Susceptibility Mapping: A Literature Review

摘要: Landslides are one of the most damaging geological hazards worldwide, threating both humans and property. Hence, there have been many efforts to prevent landslides mitigate damage that they cause. Among such efforts, studies on mapping landslide susceptibility. Geographic information system (GIS)-based techniques developed applied widely, now main tools used map We reviewed status susceptibility using GIS by number papers, year, study area, landslides, cause, models applied, based 776 articles over last 20 years (1999-2018). The published annually increased rapidly time. total area spanned 65 countries, 47.7% areas were in China, India, South Korea, Iran, where more than 500 27.3% all occurred. Slope (97.6% articles) geology (82.7% often implicated as causes, logistic regression (26.9% frequency ratio (24.7% article) widely models. analyzed trends causes simulate landslides. similar each but machine learning popularity In future, should be investigated improve generalizability accuracy results. Furthermore, especially those related topography soil, considered applied. Finally, hazard risk maps studied addition maps.
