The Qin-Mang River Basin is an important biodiversity conservation area in the Yellow Basin. Studying spatiotemporal changes its ecosystem services (ESs) and trade-offs synergies (TOSs) between them crucial for regional ecological protection high-quality development. This study, based on land use type (LUT), meteorological soil data from 1992 to 2022, combined with InVEST model, correlation analysis, spatial autocorrelation explores impacts of use/land cover (LUCCs) ESs. results show that: (1) driven by urbanization economic development, expansion built-up areas has replaced cultivated forests, 35,000 hectares farmland lost, thereby increasing pressure ESs; (2) ESs overall downward trend, habitat quality (HQ) deteriorated, carbon storage (CS) remains stable but low CS expanded, sediment delivery ratio (SDR) water yield (WY) fluctuate due human activities climate influence; (3) TOSs change dynamically, strong among HQ, CS, SDR. However, scarcity, negative HQ WY strengthened; (4) analysis reveals that 1992, significant positive existed northern northwestern regions, negatively correlated other services. By accelerated intensified trade-off effects southern eastern leading degradation. study provides scientific support sustainable management policymaking watershed ecosystems.

Humans and predators occupy dominant positions in ecosystems are generally believed to play a decisive role maintaining ecosystem stability, particularly the context of virus transmission. However, this may not always be case. By establishing some transmission models that cover both human perspectives predators, we have drawn following conclusions: (1) Controlling vaccination activities from perspective can potentially lower rate improve herd immunity, thereby indirectly protecting unvaccinated risk groups. (2) In ecosystem, does determine spread viruses. Once ecological balance between prey is disrupted, there scenarios where predator populations die out, overpopulate, or go extinct. such cases, has little impact, system cannot restore itself new equilibrium state. case, even if humans intervene, it difficult change fate species extinction. (3) situations maintain stable state, attitudes actions critical. Human intervention directly affect recovery hosts, rapidly reducing infection mitigating harm caused by virus. If do remain infected for long time, posing serious threat ecosystem.

Terrestrial ecosystems are vital carbon sinks that can effectively restrain the rise in CO2 atmosphere. How ecosystem storage (CS) semi-arid watershed areas with slow urbanization is affected by comprehensive factors of environment and land use, along its temporal spatial changes has still not been fully explored. Notably, there a paucity research on development trends CS rapid deformation belt slopes from eastern margin Qinghai–Tibet Plateau to Loess Plateau. Taking Bailong River Basin (BRB) as an example, this study combined GeoSOS-FLUS, InVEST model, localized “social–economic–nature” scenario simulate long-term dynamic evolution CS. The aim was how topographic use change, their interactions impact gradient effects steep-slope areas, then find out relationship between explore strategies improve regional sink capacity. results showed following: (1) BRB increased year year, total increase 558 tons (3.19%), significant heterogeneity, mainly due conversion woodland arable land; (2) except for type, inverted U-shaped, showing complex response; (3) it estimated 2050, under protection natural scenarios, will decrease 0.07% 0.005%, respectively, encroachment undeveloped mountain while ecological gives priority protecting grassland, 0.37%. This supports implementation targeted measures through zoning, provides reference policy makers similar regions manage heterogeneity CS, helps further strengthen global climate change mitigation efforts.
