Abstract

The invention discloses a regional debris flow disaster risk assessment method which comprises the following steps: a regional debris flow disaster risk assessment model is called; a risk assessment plug-in is created according to the regional debris flow disaster risk assessment model; at least one disaster-gestating factor and at least one disaster-inducing factor of at least one debris flow disaster site in a region of interest acquired from different data sources are input to the risk assessment plug-in, and at least one disaster-bearing body vulnerability evaluation factor is also input to the risk assessment plug-in. The risk assessment plug-in is used for executing the following operations that a debris flow disaster sensibility index is calculated based on at least one disaster-gestating factor, a debris flow disaster danger index is calculated based on the debris flow disaster sensibility index and at least one disaster-inducing factor, a debris flow disaster vulnerability index is calculated based on at least one disaster-bearing body vulnerability evaluation factor, a debris flow disaster risk index is calculated based on the debris flow disaster danger index and the debris flow disaster vulnerability index, and a debris flow disaster risk is assessed according to the calculated debris flow disaster risk index.

Description

technical field [0001] The invention relates to a method for estimating the risk of regional debris flow disasters. Background technique [0002] Disaster is an objective event of energy exchange in the celestial body and the earth's atmospheric system, and the movement of matter in the ecosphere. The Earth's atmospheric system consists of the lithosphere, hydrosphere, atmosphere, and biosphere. Natural disasters are a system that is organically combined with atmospheric disasters, biological disasters, and geological disasters. [0003] Taking China as an example, the natural geography, geological structure, topography and climate conditions are complex, and geological disasters are widely distributed, with many types, high frequency and high intensity. It is one of the countries with the most serious geological disasters in the world. According to the destruction form, dynamic effect, material composition and destruction rate of geological disasters, China's geological di...
