Enhancing earthquake disaster response capacity in super-large cities constitutes a significant aspect of current earthquake emergency research in China. Utilizing a relative microscopic analysis of scenario elements and their interactions,we establish a scenario model based on a knowledge meta-model. To address the uncertainty inherent in earthquake catastrophe scenario deduction,we establish fuzzy rules through interactions between knowledge elements. These rules facilitate matching uncertain scenario information with fuzzy rules,enabling the assessment of scenario deduction outcomes and possibilities. Subsequently,through case analysis,we categorize post-earthquake scenarios into five emergency response stages. The generation of earthquake catastrophe emergency tasks is achieved through scenario deduction,thereby validating the scientific base and practicality of our research method. Moreover,this approach provides valuable insights for emergency capability assessment,contributing to the enhancement of earthquake disaster response capacity.
