Problems solved by technology

"Grassland fire risk" lacks the research on the social factors of grassland fire formation (such as human reasons and economic factors, etc.), so the assessment results of grassland fire risk often vary greatly from the actual situation

Embodiment

[0034] Grassland fire risk assessment in Xilin Gol League;

[0035] Utilizing the index system of the present invention, this example selects the distance from the residential area, the distance from the road network, the weather index, the characteristics of combustibles and the terrain as the risk factors, and selects the economic density, population density and infrastructure of the grassland area to generate exposure to the grassland area. At the same time, the grassland fire protection capability of Xilin Gol League is classified and graded. Using the grassland fire risk assessment model to calculate, and then comparing the grassland fire risk assessment results with the daily occurrence cases of grassland fire, it is found that the two have a strong correlation.

Abstract

The invention discloses a northern grassland fire hazard risk grade rapid assessment method. A distance from a residential site, a distance from a road to network, a weather index, a combustible matter characteristic and a landform are selected as risk factors, and grassland area economic density, population density and basic facilities are selected for generating grassland area exposure and vulnerability indexes, such that the accuracy of grassland fire hazard risk assessment is improved, and the present situation of backward assessment of grassland fire hazard risk assessment is changed; the grassland fire hazard management capability can be enhanced; and a basis can be provided for grassland fire hazard insurance.

Description

technical field [0001] The invention relates to the field of fire assessment, in particular to a method for quickly assessing fire risk levels in northern grasslands. Background technique [0002] Grassland fires are sudden, destructive, difficult to deal with and rescue, and extremely harmful to grassland resources. At the same time, the occurrence of grassland fires also poses a great threat to the life and property of people in pastoral areas, and has a huge impact on economic construction and social stability. The current grassland fire management mainly focuses on the risk factors of fire formation, such as combustibles, terrain, meteorological elements, etc., which is commonly referred to as "grassland fire risk". "Grassland fire risk" lacks research on the social factors of grassland fire formation (such as human causes and economic factors, etc.), so the assessment results of grassland fire risk often vary greatly from the actual situation. [0003] Grassland fire ...
