Embodiment Construction

[0015] The preferred specific embodiment of the slide rule for quickly checking the grassland fire danger level of the present invention is that the quick look-up table for the grassland fire danger level is provided on the slide rule. The quick calculation table includes the fire risk index corresponding to multiple fire risk factors such as air temperature, relative humidity, precipitation, wind, etc., and also includes the comprehensive fire risk index obtained by the weighted average of multiple fire risk indices and the fire risk index corresponding to the comprehensive fire risk index grade. According to local conditions, other fire risk factors can also be added, such as local terrain conditions, human activities, etc.

[0016] When calculating the weighted average of multiple fire risk indices in the quick calculation table, the weights of multiple fire risk indices can be respectively: temperature factor fire risk index 30-35%, relative humidity factor fire risk index...

Abstract

The invention discloses a quick search ruler for grassland 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; the four basic fire danger factors are taken as grassland fire risk indexes; the weighted average of fire danger indexes of the four fire danger factors is taken as a comprehensive fire danger index; and a corresponding fire danger class is obtained according to the comprehensive fire danger index. The grassland 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 grassland fire danger.

Description

technical field [0001] The invention relates to a fire danger forecasting technology, in particular to a grassland fire danger level quick checking slide rule. Background technique [0002] As the global climate warms, the number and size of catastrophic grassland fires around the world are increasing year by year. [0003] Prairie Fire Danger Weather and Fire Danger Levels Daily fire preparedness relies heavily on forecasts of fire weather forecasts and fire danger levels because they provide an indication of how "severe" the fire danger will "get" each day. The meaning of grassland fire risk is the degree of danger of grassland fire, that is, the possibility of grassland 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 t...
