The Coupling Coordination and Influencing Factors of Urbanization and Ecological Resilience in the Yangtze River Delta Urban Agglomeration, China

Abstract

Twenty-six cities in the Yangtze River Delta urban agglomeration were taken as the research object, and this study comprehensively evaluated urbanization quality and ecological resilience from 2005 to 2020. On this basis, the spatiotemporal evolution characteristics and main influencing factors of the coupling relationship between urbanization and ecological resilience were systematically explored using a coupling coordination model and panel Tobit regression model. The results can be summarized as follows: (1) from 2005 to 2020, the quality of urbanization in the Yangtze River Delta urban agglomeration continued to grow, the level of ecological resilience grew slowly and fluctuated, and the development among municipalities tended to be balanced. (2) The overall coupling coordination degree of urbanization and ecological resilience showed a continuous increasing trend, and the coupling coordination type changed from basic coupling coordination to good coupling coordination. The number of cities with lagging urbanization quality decreased significantly; spatially, the gap in the coupling coordination degree between municipalities narrowed, and the cities with good coupling gradually clustered. (3) The results of the panel Tobit regression showed that the differences in the spatial evolution of coupling coordination mainly resulted from the interaction of drivers such as real utilized foreign capital, per capita GDP, carbon emission intensity, the proportion of science and technology expenditure to fiscal expenditure, the ratio of per capita disposable income of urban and rural residents, fixed asset investment in municipal utility construction, and the index of ecological land area ratio. In the future, the coupling coordination degree of urbanization and ecological resilience should be improved based on the type of coupling coordination according to local conditions, and the seven influencing factors should be carefully examined to accelerate the high-quality integrated development of the Yangtze River Delta.

Spatio-Temporal Evolution of Ecological Resilience in Ecologically Fragile Areas and Its Influencing Factors: A Case Study of the Wuling Mountains Area, China

“…The Wuling Mountains region is experiencing ecological and environmental issues like soil erosion, vegetation degradation, and frequent landslides and mudslides. The study revealed that the ecological resilience of the Wuling Mountains area between 2000 and 2020 was primarily characterized by medium and medium-high levels [15], and the growth of ecological resilience was slow and fluctuating [58], with a general upward trend [57]. The ecological resilience of the Wuling Mountains area shows obvious spatial heterogeneity and spatial agglomeration, which is consistent with the spatial distribution characteristics of natural ecological resilience in China [59].…”

Temporal and Spatial Analysis of Coupling Coordination in Beijing–Tianjin–Hebei Urban Agglomeration: Ecology, Environment and Economy

“…The degree of coupling (CD) and the degree of coordination of coupling (CCD) reflect the interaction and coordination between indicators, respectively [3,70]. In this study, correlation models were used to explore the relationship between the economy, ecology, and environment [71]. The expressions for the coupling degree and coupling coordination degree are as follows:…”

“…To quantitatively classify the coupling degree and coupling coordination degree, the coupling degree was categorized into four levels, and the coupling coordination degree was classified into five levels. The classification scheme used in this study is presented in Table 3 [71].…”

Can the Establishment of National Parks Promote the Coordinated Development of Land, the Environment, and Residents’ Livelihoods?

“…To date, the majority of both national and international studies examining the interplay among land, the economy, and ecology has originated from a solitary subsystem or has focused on the interconnection and synchronization of two subsystems, with a lesser emphasis on the interplay among all three subsystems [4,5]. Earlier research primarily concentrated on the qualitative analysis of implications, connections, and traits [6], whereas subsequent studies predominantly utilized quantitative research models [7][8][9]. In the majority of contemporary studies, a systematic evaluation index system is developed by employing methods like the entropy value, principal component analysis, and multiindex comprehensive evaluation, and the comprehensive score is computed by a coupling Land 2024, 13, 704 2 of 18 coordination model [10][11][12].…”
