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.
The construction of hydropower projects has resulted in a significant number of reservoir displacements. Resettlement is unavoidably going to be a difficult problem to solve. Employment can provide endogenous economic sources for resettles as a key measure to address the issues of resettlement and development. While most researchers focused solely on its exogenous impact, they overlooked the employment psychology and internal drive intention of resettles, which are critical factors for resettlement programs to be successful. It is critical to study the resettles willingness and action mechanism for employment in order to obtain stable living resources through employment. Based on this, we use the China Three Gorges Project reservoir resettlement as an example and employ grounded theory to survey resettled employees’ employment willingness and the mechanisms underlying their employment behaviors. Our research concludes that: (1) Asset expulsion affects resettles’ employment, and the primary reason for their employment is an urge to reclaim their livelihood. (2) Government incentives and market opportunities foster favorable conditions for employment after resettlement. Family pressures and social ties are important motivators for resettled workers. (3) Individual characteristics are the most important factors influencing whether someone chooses to work. Hence, our findings could pave the way for a specific path to guide resettlement employment and serve as a reference for promoting the stable development for resettles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
