“…This conclusion confirms the findings of some studies (Tang et al [62]; Zou and Ma [63]) but is contrary to those of others (Bao et al [64]), due to the difference in spatial scale of research objects. to 2019, the carrying status of the environmental subsystem in the Yangtze River Economic Belt showed an overall improvement trend, which is consistent with Liu et al [65] and Yang et al [66], but contrary to Zhang et al [67]. Anhui, Hubei, and Jiangxi realized the transition from ecological deficit to balance, Sichuan from balance to surplus, and other provinces and cities except Shanghai maintained their original status.…”

As a rigid constraint of the scale and speed of regional economic-social development, carrying capacity is an endogenous variable of regional sustainable development potential. Concepts such as ecological footprint and virtual water have been introduced into the research field of carrying capacity, but dynamic and comprehensive problems in carrying capacity have not been effectively solved. This paper attempts to overcome these limitations by taking the regional factor aggregation degree as the weight and the regional green GDP as the carrying object. Based on the economic-social supplying force, resource supporting force, and environmental constraint force, from the perspective of comprehensive factors assessment, we have constructed an evaluation system of regional carrying capacity index, including mineral, water, and bioecological resources, as well as labor and other factors, and evaluated the regional carrying capacity of 11 provinces and cities along the Yangtze River Economic Belt. The results indicate that (1) the supporting force of the resource subsystem becomes the most critical factor affecting the carrying capacity of the Yangtze River Economic Belt, and the cross-regional flow potential of resource factors increases the regional carrying capacity threshold. (2) The regional carrying capacity, economic-social, resource and environmental subsystems of the Yangtze River Economic Belt are steadily improving, and the overall trend is positive. The quantified dynamic evaluation of regional economic-social, resource and environmental carrying capacity provides a theoretical support for the construction of the Yangtze River Economic Belt eco-priority green development demonstration area.

“…Ecological carrying capacity (ECC) reflects the ability of social and economic sustainable development under the condition of ensuring reasonable exploitation of natural resources and virtuous circulation of ecological environment in essence (Wei et al, 2020;. Scientific evaluation of ECC plays an important role in improving carrying capacity of ecosystems and coordinating the relationship between protection and development (Yang Y. et al, 2022). The construct ecological security pattern (ESP) construction is a specific measure taken to achieve various ecological protection goal, which provides an efficient spatial planning approach to improve ecological carrying capacity and alleviate the contradiction between ecological protection and economic development (Cao et al, 2022;Ding et al, 2022).…”

The West Liaohe River Basin (WRLB) is a typical agro-pastoral interlaced zone in Northeast China where excessive economic development activities brought great pressure on the ecosystem and caused a series of ecological problems, having a negative effect on regional ecological carrying capacity (ECC). The rational construction of ecological security pattern (ESP) is an effective way to improve regional ECC and alleviate the contradiction between ecological protection and economic development. In this study, taking the WLRB as an example, spatiotemporal changes of ECC in the WLRB from 2000 to 2020 were explored by using spatial principal component analysis (SPCA). Furthermore, ecological sources were determined by coupling ECC evaluation results with important ecological patches such as natural protected areas, and the minimum cumulative resistance (MCR) model combined with the circuit theory method were employed to identify ecological security zoning, ecological corridors and key ecological nodes. Then a comprehensive ESP of the basin was constructed. The results show as follows: 1) The ECC of the overall WLRB was at medium carrying level, yet was spatially differentiated, which decreased from the periphery to the center of the basin in general. ECC showed a fluctuating upward trend from 2000 to 2020. 2) The ecological source area of the WLRB was 21926.91 km², accounting for 17.33% of the total study area. The ecological sources were seriously fragmentated and mainly distributed in the mountain area. The area of ecological conservation zone, optimized buffer zone, ecological transition zone, ecological prevention and control zone were 55672.69 km², 32662.24 km², 23862.84 km² and 12021.04 km², accounting for 44.82%, 26.29%, 19.21% and 9.68%, respectively. We also extracted 95 ecological corridors (with a total length of 3130.97 km), 49 ecological pinch points (with a total area of 200.33 km²) and 30 ecological barrier points (with a total area of 318.30 km²), constituting a “points-lines-planes” comprehensive ecological security pattern. This research can provide scientific reference for the protection and restoration of ecological environment and regional sustainable development.

The evaluation of ecological sustainability is significant for high-quality urban development and scientific management and regulation. Taking the Chengdu urban agglomeration (CUA) as the research object, this paper combined the three-dimensional ecological footprint model (3DEF) and random forest to evaluate the ecological sustainability of the study area and identify the influencing factors. The study results indicate that: (1) From 2000 to 2019, the ecological sustainability of Chengdu urban agglomeration was divided into four types, and the overall ecological sustainability of this region showed a downward trend. The areas with higher ecological sustainability were mainly distributed in the northern part of the urban agglomeration (Mianyang City) and the southern part (Leshan City and Ya’an City), while the cities in the central region (Chengdu City, Meishan City, and Ziyang City) had lower ecological sustainability. (2) The main factors affecting the ecological sustainability of urban agglomerations are industrial wastewater discharge, industrial smoke (powder) dust discharge, and green coverage of built-up areas, followed by urbanization and population size. Through this study, we have two meaningful findings: (a) Our research method in this paper provides a new way to study the factors affecting the ecological sustainability of urban agglomerations. (b) The results of the identification of influencing factors might be the reference for urban environmental infrastructure construction and urban planning.
