Abstract

The invention discloses an InSAR deformation monitoring result interpretation method for landslide, and the method comprises the steps: delineating an initial boundary of a landslide body through an optical remote sensing image, correcting the boundary through combining with an InSAR deformation rate monitoring result, and obtaining a boundary range of the landslide body through integration; within the boundary range, carrying out regional grading division on the landslide mass deformation degree by using an InSAR deformation rate result; obtaining a spatial evolution rule of the landslide mass based on the digital elevation data and the deformation quantity result of each stage; and determining key monitoring points of the landslide mass based on a deformation area grading result and spatial evolution rule information. The method can effectively extract information such as evolution rules of landslide boundaries and landslide disaster earth surface deformation in a monitoring area. Through grading the apparent deformation of the landslide disaster and analyzing the spatial evolution rule, the application of the traditional InSAR deformation monitoring technology in the landslide disaster evaluation work is promoted, and meanwhile, richer InSAR reference information is provided for the analysis of the evolution rule of the landslide disaster.

Description

technical field [0001] The invention relates to the technical field of landslide deformation monitoring, in particular to an InSAR deformation monitoring result interpretation method for landslides. Background technique [0002] Landslides are a common type of geological disasters in my country. The deformation monitoring of landslide bodies is of great significance for the prevention and control of landslide disasters. InSAR technology has the ability to carry out surface deformation monitoring in a large range, high precision, and non-contact. The monitoring of landslide mass is an important application field of InSAR deformation monitoring technology. The result obtained by InSAR technology is the deformation value of the monitoring area along the line of sight of the satellite, and the landslide disaster has the particularity that it is greatly affected by topographic factors, which directly affect the development, potential energy and sliding distance of the landslide. ...
