“…For example, Ruan, JE integrates urban economy, society and ecology as elements of the evaluation model [ 54 , 61 ] in the evaluation of urban flood resilience by using index system. At present, methods include the fuzzy comprehensive evaluation method (PCA), principal component analysis and analytic hierarchy process [ 62 ], factor analysis [ 63 ], TOPSIS [ 64 ] and other methods. The weights of toughness indexes were ranked to reflect the strengths and weaknesses of each evaluation object or index.…”

In recent decades, climate change is exacerbating meteorological disasters around the world, causing more serious urban flood disaster losses. Many solutions in related research have been proposed to enhance urban adaptation to climate change, including urban flooding simulations, risk reduction and urban flood-resistance capacity. In this paper we provide a thorough review of urban flood-resilience using scientometric and systematic analysis. Using Cite Space and VOS viewer, we conducted a scientometric analysis to quantitively analyze related papers from the Web of Science Core Collection from 1999 to 2021 with urban flood resilience as the keyword. We systematically summarize the relationship of urban flood resilience, including co-citation analysis of keywords, authors, research institutions, countries, and research trends. The scientometric results show that four stages can be distinguished to indicate the evolution of different keywords in urban flood management from 1999, and urban flood resilience has become a research hotspot with a significant increase globally since 2015. The research methods and progress of urban flood resilience in these four related fields are systematically analyzed, including climate change, urban planning, urban system adaptation and urban flood-simulation models. Climate change has been of high interest in urban flood-resilience research. Urban planning and the adaptation of urban systems differ in terms of human involvement and local policies, while more dynamic factors need to be jointly described. Models are mostly evaluated with indicators, and comprehensive resilience studies based on traditional models are needed for multi-level and higher performance models. Consequently, more studies about urban flood resilience based on local policies and dynamics within global urban areas combined with fine simulation are needed in the future, improving the concept of resilience as applied to urban flood-risk-management and assessment.

“…Combined with the theory of safety science [11], socio-technical systems [45], and the four elements theory of accidents [10,46], considering that the construction system is affected by personnel, machinery, environment, management, and other factors [47,48], the high-speed railway subgrade construction system in goaf sites is divided into four subsystems: organization member system, material technology system, management system, and environmental system.…”

Resilience Evaluation of High-Speed Railway Subgrade Construction Systems in Goaf Sites

When the high-speed railway construction project passes through goaf sites, the uncertain impacts from internal and external environments faced by the system are gradually characterized by complexity and variability, and the disastrous consequences are becoming increasingly prominent. The risk resistance ability and accident recovery ability of the high-speed railway subgrade construction system are crucial for improving the safety management level of the construction site. Based on the concept of resilience, this paper discusses the connotation of resilience applicable to the construction system of high-speed railway foundations in goaf sites, and an evaluation index system including 25 indicators is constructed. Then, the resilience evaluation model is constructed by ANP, entropy weight method and fuzzy comprehensive evaluation method. Taking the construction system of Taijiao high-speed railway subgrade in the underlying goaf as an example, this model is verified. The verification results show that the grade of construction system is II (high resilience). The evaluation result is consistent with the actual engineering situation, and the evaluation model is effective. It can be used as a theoretical basis for safety management of high-speed railway construction projects, and a full process analysis method based on resilience theory is established.

“…Although these two methods use quantitative analysis, it is not scientific enough to evaluate UR because that the subjectivity caused by human interference factors makes the index ranking values different. There are also studies that have constructed an entropy weight model (Zhang et al, 2021) and a PCA (principal component analysis) method (Wu, 2021) to evaluate the level of UR. Even these two objectively analyze the impact of system data with high dimensional, nonlinear and non-normality on the UR to a certain extent, the correlation between different systems was ignored.…”

The acceleration of urbanization created a series of problems such as water shortage crisis and serious water pollution which brought the vulnerability of urban water resources, thus affected the economic and social development of city and increased risk of external impact on the urban system. Therefore, improving urban resilience (UR) from the viewpoint of water resources plays an essential role in resisting external shocks. Our paper based on 21 cities along the Yangtze River Economic Belt’s (YREB) lower reaches relevant data from 2010 to 2018, constructs a new UR evaluation framework of “Economy-Society-Infrastructure-Water Resources”. Then the Projection Pursuit Evaluation Model of Real Coding based on Accelerating Genetic Algorithm (RAGA-PP) is used to measure the UR scientifically, Geographic Detectors (GD) method detected and analyzed the UR driving factors. The results present that: (1) The general level of UR in study area was low and characterized by attenuation from central cities to marginal cities, among them Shanghai is the highest (0.651), while Chizhou is the lowest (0.178). The resilience of cities along the YREB’s lower reaches shows a downward trend. (2) Compared with the UR without considering water resources, the UR from the perspective of water resources is relatively higher. Which means that cities along the YREB’s lower reaches have enhanced their ability to deal with external pressure and impact from the perspective of water resources. (3) Water resources and Infrastructure were two factors affected the spatial diversity of UR along the YREB’s lower reaches in 2018 and their average explanatory power of factors increased by 30.610% and 139.035% respectively; the explanatory power of Economy (5.270%) and Society (1.342%) were relatively smaller. With these findings our paper provides relevant suggestions to enhance UR along the YREB’s lower reaches from the perspective of water resources.
