Forest steppe fire risk forecast decision-making method and device and computer equipment

Abstract

The invention relates to the technical field of fire prevention and control, and discloses a forest steppe fire risk prediction decision-making method and device and computer equipment, and the method comprises the steps: carrying out the fusion of ground feature reflection spectrum data of a forest steppe region, ground climate data, geological exploration data and other multi-source heterogeneous data; inversing the temperature vegetation drought index and the vegetation analysis current condition by using an inversion technology, and estimating a future time sequence of a temperature vegetation drought index forecast value based on a temperature vegetation drought index forecast model obtained by modeling; secondly, predicting the future risk degree of the forest steppe region by using the future time sequence of the temperature vegetation drought index forecast value, the water source distance and the vegetation flammability characteristics, analyzing the current vulnerability of the forest steppe region by using the forest ecological asset value and the population density, and finally, determining the temperature of the forest steppe region on the basis of the future risk degree and the current vulnerability. And determining forest and steppe fire risk forecasting decisions in each future time so as to provide accurate deployment decision suggestions for forest and steppe fire prevention.

Description

technical field [0001] The invention belongs to the technical field of fire prevention and control, and in particular relates to a decision-making method, device and computer equipment for forest and grassland fire risk prediction. Background technique [0002] Forest and grassland fires refer to the burning phenomenon of forests and grasslands that loses human control, spreads and expands freely in forests and grasslands, and brings certain harm and losses to forests, grasslands, ecosystems and human beings. Forest and grassland fires are a kind of natural disasters that are sudden, destructive, and difficult to deal with and rescue. They not only seriously damage forest and grassland resources and ecological environment, but also cause great harm to people's lives, property and public safety. Economic sustainable development and ecological security pose a huge threat. The specific hazards are shown in the following aspects: burning forest and grassland vegetation resource...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the existing forest and grassland fire prevention and control system, the current fire prevention energy is insufficient and the accurate deployment decision-making suggestions cannot be obtained in advance, the purpose of the present invention is to provide a forest and grassland fire risk forecasting and decision-making method, device, computer equipment and computer The readable storage medium can analyze the time and space scales to obtain forest and grassland fire risk forecasting decisions that can provide accurate deployment decision-making suggestions for forest and grassland fire prevention, so that fire prevention preparations can be strengthened at the time and area where forest and grassland fires are prone to occur. Before disasters come, it is possible to respond to disaster impacts early and accurately, and to respond to fire prevention in a timely manner in areas where forest and grassland fires may occur, so as to ensure that major forest and grassland fires and mass death and injury accidents do not occur, which is convenient for practical application and promotion
