Embodiment Construction

[0077] The technical solution of the present invention will be described below in conjunction with specific embodiments and accompanying drawings.

[0078] Such as figure 1 Shown is a flow chart of a method for evaluating the ability to prevent and control mountain torrent disasters of the present invention, as figure 1 Shown:

[0079] Step 1. According to the units to be evaluated, select reasonable indicators and build an evaluation system. Collect relevant data of the area to be analyzed as initial data, including 35 indicators such as forest coverage, annual average rainstorm, 24-hour maximum rainfall, proportion of exposed population in dangerous areas, house value in dangerous areas, and density of mountain torrent disaster management agencies. Including 28 quantitative indicators and 7 qualitative indicators. Indicators can be divided into three categories. The first category is statistical scenario evaluation indicators that can be obtained by querying project-relat...

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...
