Block-level space function degradation identification method, device, equipment and product
By constructing propagation rules and functional degradation identification methods for urban system units at the street level, the problem of spatial functional degradation caused by the propagation of rainstorm geological disasters within the urban system is solved. This enables accurate identification and quantification of spatial functional degradation at the street level, supporting urban planning and governance.

Abstract
The application discloses a kind of block-level space function degradation identification method, device, equipment and product, the method includes according to the block-level city system unit system in target area and rainfall condition determines the disaster trigger unit of the target area;According to the propagation channel between each city system unit in the block-level city system unit system, the propagation rule of the disaster trigger unit to the city system unit is established;According to the propagation rule and the city system unit, the block-level space function degradation result of the target area is determined.The disaster trigger unit is determined, the propagation rule is established and the space function degradation result is identified, can be converted into block-level city system function influence by storm geological disaster, realize the propagation identification of storm-induced geological disasters in block-level city system, accurately determine block-level space function degradation result.
