View abstract on PubMed
Summary
This summary is machine-generated.Urban resilience in Zhejiang Province shows a positive trend, but economic, infrastructure, and social resilience are weakly coordinated. Improving economic-infrastructure coordination is key for sustainable urban development.
Area Of Science
- Urban planning and sustainable development
- Resilience studies
- Regional economics
Background
- Urbanization and climate change necessitate enhanced urban resilience for sustainable development.
- Assessing the interconnectedness of economic, social, infrastructure, and ecological resilience is crucial.
Purpose Of The Study
- To analyze the coupling coordination relationship within the Economic-Social-Infrastructure-Ecological resilience (ESIE) quaternary system and its binary subsystems in Zhejiang Province.
- To identify key factors influencing overall urban resilience coordination.
- To provide policy recommendations for enhancing sustainable urban development.
Main Methods
- Utilized panel data from Zhejiang Province (2014-2022).
- Employed the coupling coordination degree (CCD) model to assess quaternary and binary system interactions.
- Applied the grey correlation model to determine the impact of binary systems on overall coordination.
Main Results
- The overall CCD of the ESIE quaternary system in Zhejiang cities shows a consistent upward trend.
- A spatial pattern of coordinated development emerges, centered around Hangzhou and Ningbo.
- Significant contradictions and low pairwise CCD exist between economic, infrastructure, and social resilience.
- The economic-infrastructure resilience binary system presents a core challenge to overall coordinated development.
Conclusions
- Urban resilience in Zhejiang is improving, but imbalances between economic, infrastructure, and social components hinder full coordination.
- Addressing the economic-infrastructure coupling coordination is critical for advancing sustainable urban policies.
- The study offers a novel framework for understanding urban resilience mechanisms and informing policy.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...
Understanding the relationship between the distributed load and shear force in structural analysis is crucial for analyzing beams subjected to various loading conditions. Consider the case of a beam experiencing a distributed load, two concentrated loads, and a couple moment.
The connection between the shear force and the distributed load for the given case can be established following the given procedure. First, consider an elemental section on the beam free from any concentrated load or...
To grasp the intricacy of real-world conditions where multiple loads are applied simultaneously to a structure, one might visualize a section passing through a specific point within a body, aligned parallel to the xy plane. This section is subjected to various forces, including original loads, normal forces, and shearing forces.
The shearing force, possessing potential directionality within the plane of the section, is simplified into two component forces running parallel to the x and y axes....
When analyzing a bent tube with a circular cross-section subjected to multiple forces, it is crucial to determine the stress distribution in order to maintain structural integrity under varied load conditions.
The process begins by slicing the tube at critical points and analyzing the internal forces and stress components at these sections, focusing on the centroid. Normal stresses, generated by axial forces and bending moments, are either compressive or tensile and vary across the section from...
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:
Conducting Experiments:
The first step is to conduct experiments by systematically varying the input variables. This is typically done using a specific experimental design, such as a factorial...
