Embodiment Construction

[0016] A preferred embodiment of the forest fire danger level quick look-up slide rule of the present invention is that the forest fire danger level quick look-up table is provided on the look-up slide rule. The quick look-up table includes multiple fire risk factors and fire risk indices corresponding to the multiple fire risk factors, and also includes a comprehensive fire risk index obtained from the weighted average of multiple fire risk indices and a fire risk level corresponding to the comprehensive fire risk index.

[0017] Multiple fire risk factors can include four basic fire risk factors such as air temperature, relative humidity, precipitation, and wind level, and can also include two revised fire risk factors such as vegetation green condition and snow cover condition. Specifically, some of the factors can be selected according to the local conditions, and other fire risk factors can also be added, such as the local terrain conditions, human activities, etc.

Abstract

The invention discloses a quick search ruler for forest fire danger classes. The search ruler is provided with a quick search table comprising fire danger indexes of a plurality of factors, and corresponding comprehensive fire danger indexes and fire danger classes. The plurality of fire danger factors comprise four basic fire danger factors, namely temperature, relative humidity, precipitation and wind speed, two correction fire danger factors, namely vegetation green condition and snow coverage, and the like. The forest fire danger classes can be conveniently searched through the quick search table on the search ruler; and the search ruler can simply, accurately and scientifically predict forest fire danger.

Description

technical field [0001] The invention relates to a fire danger forecasting technology, in particular to a forest fire danger level quick checking slide rule. Background technique [0002] With global warming, the number and area of ​​catastrophic forest fires worldwide are increasing year by year. [0003] Forest Fire Danger Weather and Fire Danger Levels Daily fire preparedness relies heavily on fire weather forecasts and fire danger level forecasts because they provide an indication of how "severe" the fire danger will "get" each day. The meaning of forest fire risk is the degree of danger of forest fire, that is, the possibility of forest fire occurrence and the possible degree of burning area (scale), fire spread and fire intensity. [0004] The fire danger level is a comprehensive index series of various fire risk factors expressed in digital form, and the comprehensive index reflects the standard measures that need to be taken at that time. [0005] At present, in ord...
