摘要

Landslide vulnerability assessment is fundamental to landslide risk management tasks. Most existing methodologies of landslide vulnerability assessment are raster-based and do not consider the exact landslide positions and possible impact areas, which inevitably makes the assessment result impracticable to a certain extent. In this paper, a slope location-based landslide vulnerability assessment model is proposed to take the advantages of GIS to address the problem. A case study of Shenzhen is carried out to verify the model. It can be concluded that the model improves the practicability and feasibility of the landslide vulnerability assessment results. This study may provide a reference for relative studies on landslide vulnerability assessment.
