Abstract
This study constructs a framework for evaluating urban spatial resilience based on five dimensions: scale, intensity, morphology, function, and benefit. Likewise, it empirically analyzes the spatial differences and influencing factors of urban spatial resilience in the Harbin–Changchun urban agglomeration from 2000 to 2020. Overall, the spatial resilience of the Harbin–Changchun urban agglomeration declined from 2000 to 2019. In addition, its ability to resist external disturbances weakened. The five dimensions of spatial resilience declined. However, urban spatial morphological resilience slightly increased. The spatial diversity of the Harbin–Changchun urban agglomeration is obvious, implying that the spatial resilience of cities in the central region, mainly in Suihua and Songyuan, is higher than in peripheral areas of the urban agglomeration, mostly in the Yanbian Korean Autonomous Prefecture, Siping, and Qiqihar. The period between 2000 and 2019 was dominated by cities with fluctuating spatial resilience. Furthermore, urban spatial resilience is influenced by a combination of factors, with economic support being the primary one. The selection of the urban spatial resilience research index system in this study is more spatially oriented and more accurately reflects the urban spatial resilience situation, which, in turn, provides a new planning perspective for urban planning in China.
Highlights
The results indicate that its influence ranked first in 2000, 2005, and 2019, second in 2010 and 2015, suggesting that the level of economic development is crucial for the spatial resilience of the Harbin–Changchun urban agglomeration
The results indicate that the interaction between any two of the three influencing factors, namely economic support, environmental construction, and social coordination, was greater than the influence of a single factor on the urban spatial resilience of the Harbin–Changchun urban agglomeration
The main findings can be summarized as follows: Firstly, the results indicate a decrease in the overall urban spatial resilience of the Harbin–Changchun urban agglomeration over a period of 20 years, suggesting a weakening of its ability to resist external disturbances
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Resilience research was first applied to the fields of engineering, physics, and ecology, but in 2002, the International Council for Advocating Regional Sustainable Development (ICLEI) first proposed the concept of urban resilience in relation to urban disaster prevention and mitigation, extending resilience research to the urban domain [1]. In the late 1990s, resilience theory was introduced in planning so as to provide a fresh perspective on planning theory by coordinating the allocation of spatial resources to cope with external uncertainties. Spatial resilience goes hand in hand with resilience theory, and cities. As complex giant systems that can regulate social order, economic development, and ecological construction, cities are excellent targets for the study of spatial resilience [2]
