Abstract

The invention belongs to the technical field of forest fire monitoring and early warning, and discloses a forest fire monitoring and early warning system, method, storage medium, and computer equipment, using L1-level data of scanning radiometers carried by Fengyun meteorological satellites; using a fixed threshold method, Extract the fire points at different times; use the visual discrimination method to dynamically track and monitor the fire process to realize the location of the fire point; use the scanning radiometer carried by the Fengyun Meteorological Satellite to normalize the vegetation index data, correct the forest fire risk index formula, combine Based on the local meteorological data, the corresponding relationship between the fire danger weather level and the forest fire is analyzed relative to the forest fire danger weather level three days before the fire. The invention has great significance for forest fire monitoring and forest fire risk early warning, provides effective information for forest fire extinguishing command and decision-making, and provides scientific reference for relevant decision-making or service departments.

Description

technical field

[0001] The invention belongs to the technical field of forest fire monitoring and early warning, and in particular relates to a forest fire monitoring and early warning system, method, storage medium and computer equipment. Background technique

[0002] At present, as one of the important components of the earth's ecosystem, the forest is an important ecological guarantee for the survival and development of human beings and various organisms. Forests not only provide material resources for human survival and development, but also play an important role in maintaining ecological processes and ecological balance, especially in protecting fresh water resources, conserving water sources, and purifying water quality. However, forest fires will bring serious harm to the forest. Forest fires not only destroy the vegetation coverage in the forest, but also cause water and soil erosion. At the same time, they will also destroy the carbon reserves in the forest and cha...
