What does this research mean for the field?

The ecological security pattern of the Sanjiang Plain is characterized by high-value ecological sources in the eastern and southern margins and severe connectivity fragmentation in central regions, which can be optimized through a four-tier zoning framework integrating ecosystem services and health. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Construct and optimize an ecological security pattern by integrating ecosystem services and ecosystem health indicators to mitigate landscape degradation and habitat fragmentation.
Quantified six ecosystem services (food production, carbon storage, soil retention, water yield, water purification, habitat quality) and evaluated ecosystem health via vigor, organization, and resilience.
Constructed ecological resistance surfaces from land use, topography, NDVI, and human disturbance, applying circuit theory to identify corridors, pinch points, and restoration barriers.
Identified an ecological spatial network dominated by north-south corridors with cross-cutting east-west linkages, with high-value source patches concentrated in eastern and southern margins.
Observed severe landscape connectivity fragmentation in central zones driven by agricultural and urban expansion, leading to a proposed four-tier ecological zoning framework.
