Abstract

The invention discloses an evaluation method for evaluating water-induced landslide disaster loss caused by climate change decline, and belongs to the technical field of geological disaster prevention and control. According to the method, a physical process model is utilized, spatial heterogeneity of surface features of all grid points on a region is considered, and rainfall threshold values corresponding to all space grid points in a region range with spatial heterogeneity are obtained; the method comprises the following steps of: selecting a landslide model, optimizing a climate mode by combining historical and climate mode data, simulating an easily-occurring area and a possibly-rushing-out and influence area of the landslide by utilizing a model, and better matching an influence range simulated by utilizing the method with disaster loss lattice point data. The problem that the climate change scene and the landslide influence in landslide disaster assessment are difficult to assess is solved.

Description

technical field [0001] The invention relates to an evaluation method for evaluating landslide disaster loss induced by climate change and falling water, and belongs to the technical field of geological disaster prevention and control. Background technique [0002] Landslide is a kind of geological disaster, which seriously endangers the production and life of local residents. my country is an area where landslide geological disasters frequently occur, and landslides cause huge economic losses and casualties every year. The impact of climate change on landslides and the assessment of the impact of climate change landslides on disaster losses is a very complex and challenging issue. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an assessment method for assessing disaster losses caused by climate change landslides, which solves the problem of difficult assessment of climate change scenarios and lands...
