都市システムの自然災害に対する受容力の構造の解明と制御の可能性

抄録

This study aims to clarify the relational structure between an urban system’s characteristics and Absorptive capacity, and to discuss the possibility to control the Absorptive capacity. Absorptive capacity is one of an urban system's ability to regenerate to a desirable situation in post-disaster phase, which is measured by the degree of damage that the system can accept. First, a differential equation model to describe the dynamics of an urban system state is established, which is then used to represent the degree of Absorptive capacity. Secondly, this study analyzes how the Absorptive capacity is influenced by the change in parameter values relating to the characteristics of the urban system in the model. Finally, the possibility to control the urban system’s Absorptive capacity is discussed based on the analysis.
