Understanding the change of land space utilization efficiency with different functions and its coupling coordination: A case study of Urban Agglomeration in the Middle Reaches of the Yangtze River, China

Abstract

Land spaces function in capacities of urban development, agricultural production, and ecological conservation, among many others. Research of land space utilization efficiency (LSUE) and coupling coordination relationships among its subsystems are significant for sustainable land space development. In this study, taking the Urban Agglomeration in the Middle Reaches of the Yangtze River (UAMRYR) as the study area, we establish a measurement index system to evaluate the LSUE (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018) and analyze its coupling coordination degree by utilizing an improved coupling coordination model. The main results include the following. (1) The average efficiency levels of urban space and agricultural space in the UAMRYR increased 2000-2018, while the average efficiency of ecological space declined. (2) The spatial pattern of the LSUE values varied greatly, with the distributions of high-efficiency and low-efficiency levels significantly different. (3) The coupling degree of LSUE includes three types, i.e., high-level coupling, break-in, and antagonism. Each coupling degree type was characterized by change over time. (4) The proportion of areas with high coupling coordination and moderate coupling coordination increased from 2000 to 2018, while the proportion of areas with basic coupling coordination, moderate imbalance, and serious imbalance declined during this period. Given that the spatial differentiation of the LSUE and its coupling coordination, it is necessary to implement a differential land space development strategy in the UAMRYR. This study is helpful to promote the efficient utilization and coordinated development of land space utilization systems.

Agricultural production efficiency estimation and spatiotemporal convergence characteristic analysis in the Yangtze River Economic Belt: A semi‐parametric metafrontier approach

“…Second, control variable index system, social economy, and environment were considered according to the relevant literature and the principles of representativeness, accuracy, and conciseness (Huang et al, 2016). Among them, the socioeconomic dimension indicators include the per capita GDP, representing the impact of local economic development on agricultural development, the number of ordinary middle school graduates, representing the education of the agricultural labor force, and the income ratio of rural residents to urban residents, representing the characteristics of rural–urban income gap (Ma et al, 2018; Yang, Yang, et al, 2023). The natural environment dimension indicators cover the annual average precipitation and annual average temperature, representing the key climatic characteristics restricting agricultural production, and the land use diversity, representing the regional land use structure characteristics (Chen & Gong, 2021; Guo et al, 2020) (please see Supporting Information for data descriptive).…”

Research on the Development of Deserticulture and Desertification Land Use Benefits Evaluation in Ordos City

“…For example, P1B1 denotes the coupling coordination between the input of deserticulture development and economic benefits of land use in subsystem interaction coupling, and P1P2 represents the coupling coordination between the input and output of deserticulture development within the system's subsystems interaction couplings. The coupling coordination relationship between deserticulture development and land use benefits across subsystems was analyzed (Figure 5) [35].…”

Synergy level of urban resilience and urban land use efficiency in the Yellow River Basin: Spatial-temporal evolution characteristics and driving factors

“…However, existing research still faces the following issues: (1) Scholars mostly discuss urban resilience or urban land use efficiency from an independent perspective [ 2 , 4 , [7] , [8] , [9] , [10] , [11] , [12] ], without studying the interactive relationship between the two. However, the sustainable and high-quality development of cities is a complex system that should not be confined to just one aspect [ 13 ]. Overemphasis on efficient land use may have a negative impact on urban security, while excessive focus on urban security may reduce the efficiency of land resource utilization.…”
