英文摘要The safe operation environment of cross-regional water diversion projects is complex and variable, with risks showing diverse, networked, and dynamic characteristics, posing significant challenges for risk prevention and control. This study attempts to explore the spatio-temporal evolution patterns of coupled risks from a knowledge perspective based on spatio-temporal knowledge graph technology. Incorporating the temporal and spatial dimensions of risk, a risk knowledge extraction method based on pre-trained language models and semantic matching is designed to construct a spatio-temporal knowledge graph. By setting a sliding time window, aggregating identical risks within the window, the spatio-temporal knowledge graph is mapped into a risk evolution network. Investigate the dynamic topological structure of the risk evolution network, and analyze the causal correlations of risks and their evolution patterns in the spatio-temporal dimension. The results indicate that the proposed method achieves high accuracy in risk knowledge extraction (with an average F1 score of 96.65%), the causal correlations of risks significantly influence their spatio-temporal evolution patterns, and the level of causal correlation is positively correlated with the propagation and diffusion of risks. Relevant research can effectively enhance the reliability of engineering management and reduce the impact of potential risks on engineering safety.
