The intensification of land use and climate change threatens watershed sustainability. These external disturbances drive complex interactions among components within socio-ecological systems (SESs). Understanding how SESs respond to these changes is crucial for developing effective integrated management strategies. Nevertheless, the nonlinear responses such remain poorly understood. To fill this gap, study proposes a network analysis method focusing on Yangtze River Basin construct an SES comprising six dimensions, revealing response coupled relationships elements land-use change. results showed that in dynamics (LUD) standardized precipitation evapotranspiration index (SPEI) altered link count importance nodes, with notable shifts vegetation landscape nodes. Importantly, strong LUD SPEI relationship between was observed, critical thresholds were identified all attributes. Furthermore, compared threshold, threshold stable at 0.24, demonstrating stronger robustness. This provides new perspective understanding SESs, has important implications sustainable ecosystem planning.

ABSTRACT The Northern Hebei Province (NHB) in China serves as a crucial geographical barrier for ensuring the ecological security of mega city‐group Beijing –Tianjin‐Hebei. Due to rapid urbanization and anthropogenic afforestation, NHB is confronted with significant challenge coordinating preservation ecosystem services (ESs) socio‐economic development. Consequently, understanding impacts these human disturbances on ESs essential future decision‐making management optimal provisions ESs. Integrated Valuation Ecosystem Services Trade‐offs Tools (InVEST) model was used evaluating long‐term trends five key NHB, namely carbon storage (CS), habitat quality (HQ), water yield (WY), net primary productivity (NPP) food production (FP). Further, trade‐offs/synergy were analyzed, bundles identified. main conclusions are follows: (1) From 1996 2020, impervious surface (+122.84%), barren (+169.74%), forest (+19.8%) shrub (+49.03%) increased; waters (−39%), cropland (−20.22%) grassland (−6.14%) decreased. (2) HQ, CS, WY decreased by −5.68%, −10.69% − 20.55%, respectively, while other increased (NPP 115.09%, FP 137.14%). Increases area improved multiple but reduced WY. significantly enhanced land use efficiency. (3) Five pairs showed synergies, another trade‐offs. trade‐offs between three (CS‐WY, FP‐WY, FP‐NPP) strengthened, synergies enhanced. (4) ecologically fragile bundle 19.44% at county level 83.89% pixel level. As evidenced ES two levels, there distinct goals different levels. planning should be based spatial which can provide necessary information support sustainable development regional ecosystems.

This study aims to develop a forest landscape stability assessment framework that integrates structure, function, and resilience assess under different landform types on the Loess Plateau, propose differentiated optimization strategies. Remote sensing images ground survey data were combined compare effectiveness of machine learning models in aboveground biomass (AGB) inversion. Meanwhile, fragmentation multifunctionality assessed, Landscape Stability Index (LSI) was proposed quantify regional stability. The main findings are as follows: (1) between 2000 2022, degree hilly gully region improved significantly, Simpson’s Diversity (SDI) value showed an increasing trend; plateau decreasing trend SDI value. higher significant changes, while more stable, with “Interior” “Dominant” dominating. (2) eXtreme Gradient Boosting model outperformed other AGB estimation, R2 = 0.81 RMSE 24.67 ton ha−1. (3) LSI generally increased, especially Yanchang, showing increase ecological stability; decreased, Baishui, weakening Based results, strategies for stabilities proposed, including hierarchical management fragmentation, multi-objective improve SDI, adaptive AGB. this can effectively landscapes, reveal differences restoration regions, provide new perspectives Plateau.

Understanding the spatial differentiation of ecosystem service (ES) interactions and their underlying driving mechanisms is crucial for effective management enhancing regional landscape sustainability. However, comprehensive analyses effects key influencing factors on ES remains limited, especially regarding nonlinear heterogeneity. We assessed validated five in National Key Ecological Function Zones (NKEFZs) China—net primary productivity (NPP), soil conservation (SC), sandstorm prevention (SP), water retention (WR), biodiversity maintenance (BM). By integrating optimal parameter geographical detector with constraint line methods, we further explored complex responses to across different functional zones. The results showed that most exhibited significant synergistic clustering. In contrast, widespread trade-off clustering was detected pairs related WR, mainly distributed Tibetan Plateau, northeast China, Southern Hills region. Due improvement ES, overall synergies enhanced from 2000 2020. dominant zones influenced a non-stationary manner, same potentially showing diverse effect types sub-regions. Additionally, role configuration sub-regions specific interaction (e.g., WR-NPP SP zones), suggesting potential achieving multi-ES through planning without altering composition. This research provides valuable insights into understanding offers scientific foundation implementation ecological protection restoration plans.

Accurately identifying and obtaining changes in ecosystem drivers the spatial heterogeneity of their impacts on services can provide comprehensive support information for ecological governance. In this study, we investigate relationship between human natural factors water-related (WESs) different sub-watersheds across various time periods, focusing four aspects: single-factor effect, nonlinear interactive effects, characteristics. Taking southern basins, which have complex topographic, climatic, economic characteristics, as a study area, area was divided into sub-basins with WESs water yield, soil conservation, purification were quantified using InVEST model five periods from 2000 to 2020, OPGD MGWR models integrated assess 15 The results show following: (1) After comparing data over multiple climate such precipitation (0.4033) are primary affecting construction (0.0688) weaker influence. direct impact is not significant short term but increases time.

Since 2000, China’s Grain-for-Green Program (GFGP) has widely adopted with aim improving ecosystem services. An accurate evaluation eco-hydrological effects for policy implementation is essential to provide references further restoration This study quantified characterized services their trade-offs/synergies using models statistical methods WLRB 1990 2020. Moreover, impact key drivers on was evaluated difference-in-differences model. Among them, mainly investigated how GFGP affects The results confirmed that water yield, carbon sequestration, habitat quality, total service decreased pre-GFGP period (1990–2000). However, this tendency reversed regions where implemented during 2001–2020. Furthermore, a synergistic relationship shown among soil conservation, quality. Additionally, there were tradeoffs between yield other three services, especially mountain areas. could restore 1.3%, 2.1%, 0.6%, respectively.
