Urban agglomerations have gradually become the most dynamic and potential regional units driven by worldwide rapid urbanization. Concentrated city-and-town areas, massive human activities and rapid economic development are common characteristics of urban agglomerations. Intense anthropogenic disturbance has dramatically changed the ecological process, and put great pressure on regional and even the global ecological security. This study focused on coupled multi-substance metabolic process to analyze the complex interactions among different urban subsystems influenced by anthropogenic activities in the urban agglomeration. The analysis of metabolic problems is beneficial to identify the ecological process changes and grasp the essential environmental problems in urban agglomeration, and to realize the scientific and orderly management of urban agglomeration environment. On this basis, the ecological risk prediction model of multi-level urban agglomeration is developed, to evaluate and reveal the spatial and temporal characteristics of ecological risk in the urban agglomeration under the condition of climate change, and to provide scientific support for further collaborative supervision to ecological security.
