Abstract

The invention provides a landslide collapse emergency evaluation method and system based on remote sensing big data. The method comprises the steps: obtaining multi-dimensional attribute parameters of a first landslide collapse position, including meteorological, hydrological, terrain and stratum lithologic parameters; obtaining first input information according to the meteorological and hydrological parameters; obtaining second input information according to the terrain and stratum lithologic parameters; obtaining a first landslide collapse emergency mode, and obtaining third input information; inputting the first input information, the second input information and the third input information into a first emergency evaluation model to obtain a first emergency evaluation result, a first landslide collapse emergency response speed and a first landslide collapse emergency effect; and performing incremental learning on the first emergency evaluation model to obtain a second emergency evaluation model, and obtaining a second emergency evaluation result. The technical problems that in the prior art, a method for evaluating a landslide collapse emergency rescue scheme timely and accurately lacks, and the rescue scheme cannot be adjusted in a targeted mode are solved.

Description

technical field [0001] The invention relates to the technical field related to geological disasters, in particular to an emergency evaluation method and system for landslides and collapses based on remote sensing big data. Background technique [0002] Geological disasters have certain complexity and uncertainty, and are more destructive. They pose a threat to the lives and property of the people, destroy buildings and even entire residential areas, and bury roads and railways at the same time, causing major damage to transportation. loss. Landslides and collapses generally belong to the instability problems of slope rock and soil mass, and their causes are often interrelated, so they can be considered as a category of problems. The remote sensing survey technology of geological disasters at home and abroad has basically formed a standardized technical process, and it is relatively mature in the interpretation, classification and production of corresponding images by remote...
