The invention provides a park environment risk
traceability and grading early warning management and control method, and belongs to the technical field of risk early warning based on
computer data processing. The method comprises the following steps: firstly, collecting
video monitoring, environment and
equipment state sensor and real-time meteorological heterogeneous data in a whole domain and a
peripheral specific
buffer zone of a park, and preprocessing the data to obtain standardized multi-
source data; dividing grid units by taking a park boundary coordinate as a reference and distributing a unique standardized code, associating standardized multi-
source data to a corresponding grid according to a rule, and performing fusion calculation on a grid-level risk characteristic value of each grid; then combining real-time meteorological data, tracking a risk
diffusion path through a reverse derivation
algorithm, positioning a
risk source position and a core range, and outputting related parameters; and finally, grid risk levels are divided according to the grid risk characteristic values and a preset threshold interval, a corresponding early warning mechanism is triggered, and early warning information is output. According to the invention, the precision of
environmental risk positioning, the reliability of
traceability analysis and the refinement degree of an early warning result are improved.
