Effective landscape management is vital for maximizing the availability of ecosystem service functions (ESF). However, how pattern simultaneously affects multiple ESF across time and space, specifically regarding changes in their relationships, has not been comprehensively evaluated. Accordingly, current study examines dynamic impact on interactions among ES trade-offs China's Yangtze River Economic Belt (YREB) from 1990 to 2020. Five key are evaluated: carbon sequestration (CS), food supply (FS), habitat quality (HQ), water retention (WR), soil conservation (SC). The geographical temporal weighted regression model adopted analyze these relationships influenced by over 30 years. Over past three decades, overall amounts FS, WR, SC have increased, with only WR exhibiting a sustained increasing trend, while CS HQ significantly decreased. trade-off coordination effects generally transitioned synergies, CS–FS change more pronounced, shifting weak (− 0.29) synergies (0.20). Significant spatial variations were also observed. Most ESF. Specifically, composition stronger influence ecosystems than configuration; however, diverse often inconsistent, requiring decision-makers continuously balance management. impacts between other (CS–SC, HQ–SC, WR–SC) consistent, most prominent CS–SC. This suggests that exerts comparatively steady CS, benefiting contributions regional land parcels. These results underscore intricate responses inter-ecosystem need Cumulatively, this provides crucial guidance policymakers designing effective policies mitigate ecological degradation.

Unveiling the Spatial Variation in Ecosystem Services Interactions and Their Drivers Within the National Key Ecological Function Zones, China

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(9), P. 1559 - 1559

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.
