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.

ABSTRACT Impairment of cultivated ecosystem functions (CEFs) is a form land degradation. However, the mechanisms driving functional transition ecosystems (FTCE) and interaction between regional differential behavior FTCE remain unclear. To address this gap, we aimed to develop theoretical framework comprehensive analytical method, which combines single‐factor simulation multi‐factor regression, based on theory agricultural‐induced production substitution from perspective use (CLU). The takes into account socioeconomic elements, representing an advancement over extant studies that focus natural ecological factors. findings show high value CEFs in China moves southwest northeast central Yangtze River Delta regions 1990 2021. occurs at both national provincial scales with U‐shaped trend rapid consumption recovery growth. Further, there are two typical paths different levels. At scale, east mainly due decline nitrogen fertilizer intensity (NFUI), western biological disaster (BDI). mechanism identified as alternative choices made by farmers for agricultural under CLU goals, jointly influenced fragmentation (CLF), scale management (CLM), adaptive capacity (BDC). Finally, recommendations encourage differentiated model all aim mitigating degradation problems.
