Embodiment 1

[0058] Such as 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...

Embodiment 2

[0095] Such as 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 mountai...

Abstract

The invention discloses a regional mountain torrent risk prediction method and system, wherein the prediction method includes: S1, predicting the weather information of all hills in the region based on a meteorological model; S2, screening out the mountains that need risk prediction based on the weather information Hill; S3. Divide the hills that need risk prediction into different risk prediction levels according to their basic information; different risk prediction levels correspond to different risk prediction periods; The preliminarily determined disaster-causing factors are screened to obtain the main disaster-causing factors affecting mountain torrents; S6. Training and generating multiple mountain torrent risk prediction models based on the main disaster-causing factors; S7. Selecting several risk prediction models with the best performance to form the final Risk forecasting model; S8. Perform flash flood risk forecasting for the hills to be forecasted. The invention realizes risk prediction for regional hills, realizes low cost, wide coverage and high processing efficiency, and improves the safety of hills.

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...
