[Coupling Coordination Measurement and Multi-dimensional Conflict Diagnosis among Territorial Space Functions]

Area of Science:

• Spatial planning and regional development
• Ecosystem services and land use change
• Human-environment interactions

Context:

• Optimizing territorial spatial patterns is vital for balanced development.
• The Poyang Lake Ecological Economic Zone faces complex interactions between urban, agricultural, and ecological functions.
• Understanding these dynamics is crucial for sustainable land management.

Purpose:

• To evaluate the coupling coordination and identify conflicts among urban, agricultural, and ecological functions in the Poyang Lake region from 2010 to 2020.
• To analyze spatial patterns and trends of these functions and their interactions.
• To provide a basis for localized territorial spatial optimization strategies.

Summary:

• Urban function predominantly increased (75.67%), especially in the north, while agricultural (77.44%) and ecological (57.66%) functions decreased, particularly in the south.
• Coupling coordination analysis revealed a dominance of imbalance recession, with a trend towards the middle, and spatial hotspots concentrated in the south.
• Function conflicts, particularly urban-ecological and agricultural-ecological, intensified, driven by urban expansion and ecological/agricultural decline, especially in river basins.

Impact:

• Highlights significant spatial disparities in territorial function coupling and conflicts.
• Underscores the need for place-based optimization strategies for sustainable territorial development.
• Emphasizes the importance of protecting ecological and agricultural spaces during urbanization.
