Evaluation of urban resilience based on Service-Connectivity-Environment (SCE) model: A case study of Jinan city, China

Abstract

Resilience has become one of the main drivers for planning city future. However, there is currently no universally accepted definition and measurement of urban resilience. This study introduces and demonstrates a Service-Connectivity-Environment (SCE) model to evaluate urban resilience. First, this paper defines urban resilience based on existing research and presents a framework for urban resilience based on service, connectivity, and environment. Second, this study introduces a SCE model used to evaluate urban resilience. This paper presents an indicator system for urban resilience assessment with eight indicators. In contrast to previous urban resilience evaluation systems, the developed evaluation system is two-dimensional. One dimension is service, connectivity, and environment, and the other is basic and coordination. Service mainly refers to urban service facilities, connectivity mainly refers to transportation system, and environment mainly refers to the landscape of green space and water bodies. Third, as an illustrative example, apply the SCE model to Jinan, Shandong Province, China. The study focuses on the temporal and spatial characteristics of urban resilience in Jinan. The analysis provides initial evidence that the level of urban resilience in the SCE dimension of Jinan City varies, and the regional gap gradually increases during the study period. The SCE model provides a general and replicable approach to resilience assessment that can be implemented for a broader range of applications.
