Urban Infrastructure Vulnerability Assessment and Its Spatial Analysis of Yangtze River Delta Urban Agglomeration in Climate Change

Abstract:

Urban infrastructure plays a key role when city responses to climate change. In order to explore the vulnerability of urban infrastructure systems and their spatial distribution characteristics in climate change， we combined three-element theory of vulnerability and spatial analysis methods and constructed spatial analysis framework of unban infrastructure vulnerability in climate change. Empirical analysis was carried out through the data of Yangtze River Delta urban agglomeration. Based on the analysis of spatial distribution and spatial correlation of the three elements of vulnerability， it is found that the spatial distribution characteristics of the three types of elements are different. The vulnerability depends more on the administrative level， economic level， and administrative region of the individual urban unit. The strategic system for reducing infrastructure vulnerability should be involved in the regional integration policy.
