Research Regarding the Coupling and Coordination Relationship between New Urbanization and Ecosystem Services in Nanchang

Abstract

The new urbanization (NU) will lead to changed land use types, affecting the ecological environment and ecosystem service value (ESV). The NU is affected by the ecological environment because of resource scarcity when the ecological environment is damaged. NU levels and ESV were used to evaluate the degree of urbanization development and value provided by ecosystem services (ES), respectively, and to analyze their coupling and coordination relationships. This study shows that (1) the Nanchang city NU increases annually, at an accelerated rate, while the city scale continuously expands. Among the various NU subsystems, economy and spatial urbanization are primary, and the remaining subsystems are secondary. (2) In terms of the area of each land use in Nanchang, arable land is the most widely distributed, followed by forest land, and water. The land type with the greatest change was development land, followed by arable land. (3) ESV declined during the study period, with water and forest land being the main ESV components. Hydrological regulation had the greatest contribution among the individual services, while maintaining the nutrient cycle had the minimal contribution. The high-value areas of Nanchang ecology were mainly located in the northeast corner and the water location in the southeast, while the low-value areas were mainly located in the central Nanchang county area. (4) The coupling degree (CD) of Nanchang’s NU and ES showed an inverted U-shaped development trend, first increasing and then decreasing. The coupling coordination degree also showed the same trend and exhibited fluctuation in the evolution process.

Evaluation of typical ecosystem services in Dabie Mountain area and its application in improving residents' well-being

“…In order to reflect the general effectiveness of the comprehensive measurement of the research system, it is necessary to build a coupling coordinated development model to compare, analyze and evaluate the advantages and disadvantages in different dimensions ( Hu et al., 2022b ). This paper introduced the coupling coordinated development degree model with reference to relevant literature ( Liao et al., 2020 ; Maimaiti et al., 2022 ).…”

Spatial–Temporal Heterogeneity of Urbanization and Ecosystem Services in the Yellow River Basin

“…The lowest is Qinghai Province, which is about 12 percentage points lower than the national urbanization rate. The urbanization level and quality of cities along the Yellow River are also obvious [26].…”

The spatio‐temporal interactive effects between ecological urbanization and industrial ecologization in the Yangtze River Delta region

“…Hu, Sarwar, and Li (2021) combined ecosystem services with multidimensional urban well‐being to construct a performance evaluation system for urban ecological well‐being, which is used to characterize the quality of urban ecological development. Hu et al (2022) explored the interactions between the subsystems of ecological urbanization from the perspective of the coupling and coordination of social urbanization, economic urbanization, and ecosystem services. Based on the selection of reasonable evaluation indicators, the objective weighting methods such as entropy weight method, principal component analysis (Pramanik et al, 2021), fuzzy comprehensive evaluation method (You & Zhang, 2017) or vertical and horizontal opening grade method (Li, 2022) can be applied to aggregate multiple evaluation indicators of ecological urbanization.…”
