This invention discloses a method and system for dynamic visual analysis of oxygen-consuming pollutants across multiple interfaces in watersheds. Addressing bottlenecks in large-scale rendering of complex watershed hydrology, such as GPU memory overflow, lack of cross-interface flux representation, and difficulty in perceiving prediction errors, this invention acquires a multi-source heterogeneous spatiotemporal sequence set of water quality data; constructs a topological directed acyclic graph (DAG) based on Strahler hierarchy in memory, and performs online hierarchical temporal aggregation algorithm in the GPU for dynamic LOD memory scheduling; generates a three-dimensional cross-medium particle streamline flux layer using Runge-Kutta numerical integration and pollution degradation constant constraints; and extracts the prediction variance field using a regularized multi-decoder scene representation network (RMDSRN), mapping it to the physical geometric roughness and fogging effects of the water surface mesh. This invention achieves hardware-level isomorphism between geographical laws and low-level memory scheduling, intuitively presenting hidden physical flux interactions and deep AI-predicted risks, significantly improving the scientific rigor and hardware / software efficiency of watershed management.
