Abstract

The invention discloses 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. This method uses the physical process model, considers the spatial heterogeneity of the surface characteristics of each grid point in the region, and obtains the precipitation threshold corresponding to each spatial grid point in the region with spatial heterogeneity; combined with historical and climate model data, the optimal The climate model was established, and then the landslide-prone area and the possible rush-out and impact area were simulated by the model. The impact range simulated by this method can better match the disaster loss grid data, which solves the problem of climate in landslide disaster assessment. Change scenarios and landslide impacts are difficult to assess.

Description

technical field [0001] The invention relates to an evaluation method for evaluating the loss of landslide disasters 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 a landslide-prone geological disaster area, and landslides cause huge economic losses and casualties every year. The impact of climate change on landslides and the assessment of climate change landslide impacts on disaster losses is a very complex and challenging problem. SUMMARY OF THE INVENTION [0003] In order to overcome the insufficiency of the prior art, the present invention provides an assessment method for assessing the disaster loss due to climate change and landslide impact, and solves the problem of difficulty in assessing climate change scenarios and landslide impa...
