Mountain fire spreading trend analysis method and device based on power grid GIS

The invention provides a power grid GIS-based mountain fire spreading trend analysis method and device, and the method comprises the steps: obtaining suspected mountain fire point data through a power grid GIS platform, and carrying out the impact analysis of external factors on the suspected mountain fire point data, thereby obtaining a mountain fire impact analysis result; a power grid GIS platform is used to carry out power grid influence forest fire identification analysis on the forest fire suspected fire point data, a forest fire identification analysis result is obtained, and power grid high influence fire points whose influence probability/degree to the power grid is greater than a set value are determined; and performing forest fire spreading trend analysis based on the forest fire influence analysis result and the forest fire identification analysis result by using a power grid GIS platform. Based on the power grid GIS information platform, the forest fire possibly threatening the power transmission
