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.

Ecosystem services (ESs) are increasingly recognized as critical to sustainable development and human well-being frequently used indicators in environmental governance policies. However, existing studies mostly assess the performance of isolated single ESs, ignoring management data needs local governments for comprehensive gate-keeping easy monitoring regional ecosystems, lacking holistic ESs. To address these shortcomings, this study assessed spatial changes five main ESs Yangtze River basin (YTRB) China by creating a indicator (CESI) using multi-source data, introduced hotspot analyses econometric models explore driving forces CESI. Results showed that during period, CESI YTRB increased from 0.44 2000 0.47 2020. High-value areas were mainly concentrated hilly mountainous regions, whereas low-value predominantly situated plain areas. From 2020, hot spots primarily located middle lower reaches YTRB. Conversely, cold upper The regression analysis revealed significant negative association between socioeconomic factors CESI, while positive natural background Of factors, average precipitation has largest effect on with each 1% increase resulting up 0.369% In contrast, GDP density had greatest impact triggering reduction 6.210%. findings suggest which integrates multiple can effectively simplify difficulty ecological regulation. mechanism indicates protection policies, when combined conditions intensity activities region, would be more coherent varying regulatory intensities.

Analyzing the complex dynamics of land use, accurately assessing ecosystem service values (ESVs), and predicting future trends in use ESVs alterations within spatial constraints policies are essential for policymaking advancing sustainable development objectives. This study analyzed use/land cover (LULC) changes Yunnan Province from 2005 to 2020. Policy were incorporated into scenario simulations, an improved equivalent factor method, Markov-PLUS model, global autocorrelation, Getis-Ord Gi* method applied predict analyze LULC under different scenarios 2030. The findings revealed following: (1) Forests grasslands dominant categories YNP, with notable patterns recorded between (2) total area increased by CNY 8.152 billion during this period, exhibiting initial decline followed gradual recovery. (3) Simulations 2030 indicated that natural would lead most extensive urbanization, while ecological conservation yield greatest increase ESVs. In contrast, only farmland led food production-related ESVs, but resulted lowest among three scenarios. These results contribute understanding impacts on provide insights formulating scientifically sound effective protection policies.
