Summary
Ecosystem services like water yield, carbon storage, and soil conservation in Suzhou fluctuated between 2000-2020, showing trade-offs and synergies. Spatial analysis revealed scale-dependent interactions crucial for ecological planning.
Area of Science:
- Ecosystem services assessment
- Spatial ecology
- Environmental management
Background:
- Understanding ecosystem service interrelationships is key for collaborative management.
- Interaction mechanisms across spatial dimensions inform conservation and planning.
Purpose of the Study:
- To evaluate water yield, carbon storage, and soil conservation in Suzhou (2000-2020).
- To analyze spatial-temporal patterns, identify hotspots, and assess trade-offs/synergies at different scales.
Main Methods:
- Integrated Valuation of Ecosystem Services and Trade-Offs (InVEST) model.
- Difference comparison method for spatial heterogeneity analysis.
- Grid and county-level scale analysis.
Main Results:
- Water yield, carbon storage, and soil conservation showed a decline-increase trend.
- Spatial patterns varied, with soil conservation showing least change.
- Trade-offs dominated water yield-carbon storage and carbon storage-soil conservation interactions at finer scales, while water yield-soil conservation showed synergy.
- Scale effects influenced spatial agglomeration.
Conclusions:
- Ecosystem service dynamics and interactions are scale-dependent.
- Findings support targeted ecological conservation strategies and spatial planning in Suzhou.
- Fine-grained management requires understanding these complex interrelationships.
