Analysis of Ecosystem Service Value Trends and Drivers in the Yellow River Delta, China

Agriculture, Journal Year: 2025, Volume and Issue: 15(3), P. 346 - 346

Published: Feb. 6, 2025

Ecosystem service value (ESV) reflects ecosystem functions and benefits; however, the factors influencing ESV mechanisms driving it in wetlands non-wetlands are not yet fully understood. The Yellow River Delta (YRD) is distinguished by presence of numerous wetland areas that both Reserve non-Reserve thus was selected as designated study area. In this study, spatiotemporal structures YRD between 2000 2020 were studied using land cover change analysis equivalent factor methodology. addition, we analyzed drivers behind geographical variability applying Geographical Detector method. results showed structure National Nature relatively stable, whereas area exhibited greater fluctuations; is, decreased 11.43% compared with more stable areas, where 4.93%. Furthermore, disparities distribution use types gave rise to a discernible spatial overall ESV, northeast exhibiting significantly higher levels southwest. Additionally, past two decades, center gravity regions has shifted towards urban centers, have migrated coastline. Normalized Difference Vegetation Index identified main driver heterogeneity. findings highly relevant regional ecological conservation promotion economic social development.

Conceptual Discrimination and Quantitative Estimation of Climate Carrying Capacity: A Case Study of China

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 1770 - 1770

Published: Feb. 20, 2025

To address the conceptual ambiguity surrounding climate carrying capacity and lack of a unified quantitative assessment method, here we integrate existing concepts propose comprehensive evaluation framework for capacity, emphasizing threshold system’s to support human activities. Additionally, incorporates carbon resource production potential, wind solar potential as its four key components, employs vector modeling approach quantitatively evaluate temporal spatial variations in across China’s provinces, municipalities, autonomous regions from 1986 2020. The results reveal that most exhibited low coefficients variation index during study period, indicating an overall stable good further development. However, Beijing, Shanghai, Tianjin demonstrated exceptionally high variation, at 62.8%, 74.3%, 74.4%, respectively, warranting attention. Tibet, Xinjiang, Inner Mongolia significantly higher indices than other areas, whereas Ningxia, Hainan, Chongqing generally displayed lower indices. This enhances theoretical offers scientific foundation formulating sustainable development policies, promoting coordinated regional development, protecting environment, addressing change.
