obtaining vector information of a landslide source surface by remote sensing identification or InSAR interpretation, and extracting parameters of the landslide source surface including area, width, slip direction, and rock type in batches based on ArcGIS software;

selecting relevant parameters based on the rock type in the parameters, and obtaining the equivalent friction coefficient according to the relevant parameters and a volume of the landslide source surface;

obtaining a landslide runout distance according to the equivalent friction coefficient, determining coordinate points of a hyperbola and a front edge boundary range according to the landslide runout distance, and performing a hyperbolic fitting on two side boundaries of the landslide source surface according to the coordinate points to obtain a side boundary range;

wherein determining the coordinate points of the hyperbola comprises:

calculating a center of gravity of the landslide source surface, obtaining P1 coordinates of a top center point of the landslide source surface, extending a first target distance from the P1 coordinates along the slip direction, while being perpendicular to the slip direction, respectively extending a second target distance to both sides from the P1 coordinates to obtain a first endpoint coordinate and a second endpoint coordinate, extending to both sides according to an expansion angle from the first endpoint coordinate and the second endpoint coordinate, and intersecting with a vertical line segment to obtain P2 coordinates and P3 coordinates; and

generating the landslide hazard zoning based on the front edge boundary range and the side boundary range.
