“…It can accurately grasp the vital role of the three modules of water purification, soil conservation, and carbon storage for regional ecological management and the enhancement of ecosystem service functions [119]. On the other hand, the equilibrium factor and the yield factor, based on the ecological footprint model, show the differences in the capacity of environmental services provided by different ecosystems and can better express the carrying capacity of various ecosystems [120]. In summary, to solve the problem of slow policy formulation and accounting results, the ecological asset optimization assessment model maintains the balance between regional socio-economic development and environmental protection.…”

Grasslands in karst ecological fragile areas can effectively mitigate climate change, conserve biodiversity, maintain human well-being, and play a significant role in improving the health of regional ecosystems and farmers’ livelihoods. Thus, the study of grassland ecological assets and ecological products comprehensively examines their effects on grassland ecosystem services based on the traditional paradigm. This procedure is crucial from a strategic perspective for rebuilding damaged grassland ecosystems in karst regions, strengthening the efficacy of desertification control, and encouraging sustainable economic growth. In this review, 143 pertinent works on grassland ecological assets and ecological products are numerically and qualitatively analyzed. The findings demonstrated the following: (i) After 2012, there was an exponential increase in the number of studies. The most frequently researched topics were ecological assets, functional enhancement, and service management contents, accounting for 82.09% of the total literature; the research regions were primarily distributed in Asia and North America. (ii) The research patterns were slowly diversifying and becoming more interdisciplinary. (iii) There are five key scientific issues to be addressed in the research on grassland ecosystems and we summarize the main developments and landmark achievements. (iv) There is an intrinsic relationship between grassland ecological assets, ecological products, and desertification control, and we propose insights into the enhancement of karst grassland ecosystem service functions based on three perspectives: fragile environment, trade-off synergy, and service management. This study provides valuable insights for the development of regional ecological livestock and the scientific promotion of integrated desertification control.

“…P NP is the average ESV per unit area of all land use types. E i is the national average ESV per unit area of ith land use type [54]. The entropy method is used to evaluate the weight of each indicator [55], which is based on that the smaller the entropy value, the greater the degree of dispersion of the index, and the greater the influence of the index on the comprehensive evaluation, thus giving a greater weight.…”

The spatiotemporal distribution of ecosystem service values (ESVs) and ecological risk are critical indicators to represent the regional ecological protection level and potential of sustainable development, which largely depend on land-use patterns. Aiming to contribute to global climate mitigation, China has proposed dual-carbon goals that would remarkably influence the land-use/cover change (LUCC) distribution. Based on the Landsat land cover data of 2000, 2010 and 2020 and multisource satellite products, several driving factors are integrated into the patch-generating land use simulation (PLUS) model to simulate future LUCC patterns for the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) under rapid urbanization, cropland protection and carbon neutral (CN) scenarios from 2020 to 2050. Spatial–temporal ecosystem service and ESVs are allocated using INVEST and the equivalent factor method and thus ecological risks are evaluated using the entropy method. Results indicate that forest growth is the largest under the CN scenario, especially in the northwestern and northeastern GBA, exceeding 25,800 km2 in 2050, which results in both the highest habitat quality and carbon storage. The largest ESVs, reaching higher than 5210 yuan/pixel, are found in the CN scenario, particularly expanding toward the suburban area, leading to the lowest ecological risks. From 2020 to 2050, habitat quality, carbon storage and ESVs improve, while ecological risks decline in the CN scenario. This research provides implications for economic and ecological balanced development and gives references to the carbon-neutral pathway for the GBA.

“…The method based on a balance between supply and demand calculates the difference between the amount of resources provided by the ecosystem and the socio-economic demand under the given development model (Xiang and Meng, 2012). By referring to the equivalence factor and yield factor of the value of ecosystem services and the supply-demand balance model of ecological carrying capacity (Liu et al, 2012;Guo et al, 2020), this paper improves the method to calculate the ecological footprint and the ecological carrying capacity. We use the ratio of potential ecological functions to the demand for such services to assess the ecological carrying status:…”

The rapid expansion of China's urban agglomerations in recent decades has resulted in over-occupied ecological spaces and increased ecological pressure that are restricting healthy regional development. This paper examines the structure and characteristics of distribution of "production-living-ecological" spaces in five mega-urban agglomerations in China: Beijing-Tianjin-Hebei (BTH), the Yangtze River Delta (YRD), Guangdong-Hong Kong-Macao Greater Bay Area (GBA), Chengdu-Chongqing (CY), and the middle reaches of the Yangtze River (MYR). We analyze spatial and temporal variations in the ecological spaces and factors influencing them from 1990 to 2020, and examine the comprehensive ecological carrying capacity and status of ecological spaces in the past 30 years based on the available water resources, regulation of water and air quality, and leisure and recreation. The results show the following: (1) Urban agglomerations in different stages of formation and development represent varying area ratios of "ecological-production-living" spaces. The modes of expansion and evolution of the living spaces are dominated by multi-center combinations as well as the spatial structure of ecological spaces, including barrier, compact, discrete, and fully enveloping spaces. (2) From 1990 to 2020, the area occupied by living spaces in urban agglomerations continued to increase significantly while that of spaces for ecological production decreased. Except in the GBA, ecological spaces have exhibited a trend of increase in area, especially in the past 10 years. The area ratios and spatio-temporal variations in the "production-living-ecological" spaces indicate that the main functions of production and ecological spaces in mega-urban agglomerations have shifted from supply to regulation and culture, and reflect the transition from rapid urbanization to sustainable urbanization in China. (3) The comprehensive ecological carrying capacities of 78.6%, 73.1%,
