Method for tracing leakage of buried gas pipeline under driving of multi-source data

The invention discloses a buried gas pipeline leakage traceability method driven by multi-source data. The method comprises the following steps: primary traceability screening based on traceability boundary division; secondary traceability screening based on comparison of the actual monitoring concentration and the theoretical maximum concentration of the underground space; third screening of high-leakage gas pipe sections based on actual alarm maximum concentration diffusion inversion; high-leakage gas pipe sections are screened for the fourth time based on prediction alarm maximum concentration diffusion inversion; performing troubleshooting priority ranking based on troubleshooting objects and result analysis; multi-point alarm troubleshooting priority correction based on information feedback; based on the dynamic traceability analysis of the underground space alarm concentration state and the space pipeline distribution, the traceability range is greatly reduced, the traceability accuracy is improved, and
