Timely and accurate prediction of gas dispersion is therefore essential for emergency decision-making and operational safety. While existing methods such as computational fluid dynamics, spatiotemporal statistics, and surrogate models emphasize prediction accuracy, they often suffer from excessive computational delays—especially critical in leak scenarios where casualties can occur within minutes. To address this gap, this paper introduces a Gaussian process-Markov random field-Kriging (GP-MRF-K) model for fast and reliable prediction of gas concentration fields. The approach integrates Markov random field (MRF) neighborhood structures into Kriging-based spatial interpolation, reducing computational complexity from O(n³) to O(n·m³), where n is the total grid points and m is the average neighbor count. Gas concentration time series are forecasted using Gaussian process regression (GPR), and the MRF-Kriging framework rapidly reconstructs the full concentration field. Validation with real ammonia concentration data from a warehouse-scale experimental setup confirms the feasibility and superiority of GP-MRF-K. With 150 training points and 10 prediction steps, the model achieves an MSE of 4660 and RMSE of 68.26, improving MSE by 67% over GPR-K (MSE=14003) and 87% over LSTM-K (MSE=36172), while attaining an R² of 0.9847. Computation time is reduced to 39.04 seconds, a 21.5% gain over GPR-K (49.72s) and a 98% reduction compared to LSTM-K (1990.85s), thereby meeting real-time emergency response requirements.
