Forest fire meteorological warning method and system

Abstract

The invention discloses a forest fire meteorological warning method and system. The system comprises a meteorological station, a data receiving terminal, a forest fire meteorological index calculation module, a forest fire meteorological level calculation module, a forest fire warning information calculating and editing module, and a warning information transmitting module. The data receiving module receives information of the meteorological station and analyzes the information, the forest fire meteorological index calculation module calculates forest fire meteorological indexes of warning sub-areas and stores the indexes, the forest fire meteorological level calculation module further calculates forest fire meteorological levels, the forest fire warning information calculating and editing module calculates warning levels and edits warning information, and the warning information transmitting module transmits the warning information to terminal users.

Description

technical field [0001] The invention relates to a method and system for early warning of forest fire danger weather. Background technique [0002] Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with and rescue. It ranks first among the three natural disasters (diseases, insect pests, and fires) that destroy forests. It not only burns to death, burns trees, directly reduces forest area, but also seriously damages forest structure and forest environment, causes air pollution and soil erosion, decreases forest biomass, weakens productivity, reduces beneficial animals and birds, and even threatens the safety of people's lives and property. Human and animal casualties. [0003] Therefore, forest fire prevention is not only an urgent need to protect natural resources, protect the ecological environment, protect forests, develop forestry and maintain social stability in forest areas, but also an important part of disaster prevention and mitiga...

AI Technical Summary

Problems solved by technology

[0005] The area of ​​ground patrol monitoring is small, the field of view is narrow, and the rugged terrain and dense forests limit the monitoring range of ground patrol, especially in remote mountainous areas that are inaccessible

Observation tower monitoring is also affected by the terrain, there are dead spots and gaps, the monitoring area is not large, smoke and fog often limit the scope of observation, and thunder and lightning weather cannot be observed on the tower

Aviation patrol is an effective method for large-scale monitoring, but the cost is high, and the cost of renting an aircraft is expensive. However, it is difficult to take off at night, in windy weather, and when the visibility is low on cloudy days. At the same time, patrols are limited by routes and time

Satellite remote sensing monitoring, its spatial resolution and time resolution are also difficult to meet the needs of real-time monitoring and early warning of forest fires

The forest fire risk forecast of the National Meteorological Administration is mainly based on the meteorological monitoring data of meteorological stations in various places. It is only of reference significance for the national scale fire risk forecast, and has no guiding significance for the forest fire risk forecast in a county
