Embodiment 1

[0058] like figure 1 As shown, the present embodiment proposes a regional flash flood risk prediction method, including:

[0059] S1. Predict the weather information of all hills in the area based on the meteorological model;

[0060] Collect the weather information of all the hills in the area, use the meteorological model to predict the weather information, and predict the weather conditions in the future. The present invention does not limit the specific meteorological model, and usually predicts the weather in the next 7 days.

[0061] S2. Screen the hills in the area based on the weather information, and select the hills that need to be predicted for flash flood risk;

[0062] my country is a mountainous country, and the area of ​​hills accounts for about 2 / 3 of the country's land area, which is far higher than the world average. Since ancient times, my country has had the habit of living near mountains and rivers, so the dense population distribution in hilly areas pr...

Embodiment 2

[0095] like figure 2 As shown, the present embodiment proposes a regional flash flood risk prediction system, including:

[0096] The weather information module is used to predict the weather information of all hills in the area based on the weather model;

[0097] Collect the weather information of all the hills in the area, use the meteorological model to predict the weather information, and predict the weather conditions in the future. The present invention does not limit the specific meteorological model, and usually predicts the weather in the next 7 days.

[0098] The first screening module is used to screen the hills in the area based on the weather information, and select the hills that need to be predicted for flash flood risk;

[0099] my country is a mountainous country, and the area of ​​hills accounts for about 2 / 3 of the country's land area, which is far higher than the world average. Since ancient times, my country has had the habit of living near mountains ...

Abstract

The invention discloses a regional mountain torrent risk prediction method and system. The method comprises the steps: S1, predicting the weather information of all hills in a region based on a meteorological model; S2, screening out hills needing risk prediction based on the weather information; S3, dividing hills needing risk prediction into different risk prediction levels according to the basic information of the hills; wherein different risk prediction levels correspond to different risk prediction periods; S4, preliminarily determining disaster-causing factors for mountain torrent evaluation; S5, screening the preliminarily determined disaster-causing factors to obtain main disaster-causing factors influencing the mountain torrent; S6, training and generating a plurality of mountaintorrent risk prediction models based on the main disaster-causing factors; S7, several risk prediction models with the best performance are selected to be combined to form a final risk prediction model; and S8, performing mountain torrent risk prediction on the hill to be predicted. According to the method, the risk prediction of the regional hill is realized, the realization cost is low, the coverage is wide, the processing efficiency is high, and the safety of the hill is improved.

Description

technical field [0001] The invention relates to the technical analysis field of mountain torrent disasters, in particular to a regional mountain torrent risk prediction method and system. Background technique [0002] The frequent occurrence of mountain torrent disasters in our country seriously threatens the safety of people's lives and property. According to statistics, the loss of life and property caused by mountain torrent disasters in my country accounts for about 40% of the total losses caused by natural disasters every year. Flash floods generally refer to floods that occur in a small area (usually within a few hundred km2) of hilly areas and are induced by heavy rainfall with rapid rise and fall (tens of minutes to several hours). The danger of mountain torrents is mainly characterized by suddenness, concentrated water volume, large flow velocity, and strong scouring force, often engulfing a large amount of sand and stones, forming mudslides and landslides, which a...
