Mountain torrent disaster control capability evaluation method

Abstract

The invention discloses a mountain torrent disaster control capability evaluation method, which comprises the steps of 1, collecting data of a to-be-analyzed region as initial data, and determining evaluation indexes; 2, directly assigning values to the quantitative indexes; carrying out index quantification on the qualitative indexes by utilizing a Delphi method and then carrying out assignment;3, determining the weight of each evaluation index by using subjective weighting and an analytic hierarchy process and objective weighting and using an entropy weight method, and determining a comprehensive weight by combining the subjective weighting method and the objective weighting method; and step 4, establishing a mountain torrent disaster control capability evaluation model, and performinganalysis and evaluation according to a model calculation result. By establishing the evaluation system and comprehensively considering the risk of the mountain torrent disasters and the mountain torrent disaster resistance, the control capacity of the mountain torrent disasters is evaluated, the disaster management level of the government can be improved, the flood control capacity of hilly areascan be improved, and the effect of mountain torrent disaster control measures can be known more visually.

Description

technical field [0001] The invention relates to the field of emergency disaster prevention, and specifically relates to an evaluation index system for mountain torrent disaster prevention and control capabilities and a method for evaluating mountain torrent disaster prevention and control capabilities. Background technique [0002] Mountain torrent disasters refer to disasters that cause losses to the national economy and people's lives and property due to floods caused by rainfall in hilly areas, mudslides and landslides induced by mountain torrents. The complex terrain and geological conditions, the climate characteristics of frequent rainstorms, the dense population distribution and the influence of human activities have led to the frequent occurrence of mountain torrent disasters in my country. Human activities in mountainous areas are concentrated, towns and major projects are distributed along river valleys, densely populated and economically dense areas overlap with m...

Problems solved by technology

[0003] Now many scholars use GIS and RS technologies to conduct qualitative and quantitative analysis on the risk and vulnerability of the study area. The evaluation of mountain torrent disaster risk, the preparation of mountain torrent disaster risk zoning and corresponding risk maps are relatively mature, but There are ambiguity and incompatibility problems in the evaluation process of mountain torrent disaster prevention and control capabilities. Using the fuzzy matter-element method to establish a model can solve this problem very well, so the establishment of this evaluation index system has practical significance
