Abstract The scientific establishment of the Ecological Security Pattern (ESP) is crucial for fostering synergistic development ecological and recreational functions, thereby enhancing urban protection, development, sustainable growth. This study aimed to propose a novel method constructing ESP considering both reconstruct by weighing relationship between protection development. Utilizing Fuzhou City as case study, comprehensive application methodologies including Morphological Spatial Analysis (MSPA), landscape connectivity analysis, ArcGIS spatial social network analysis (SNA), circuit theory employed develop Recreational (RSP). A trade-off matrix created facilitate reconstruction ESP, delineate functional zones, identify strategic points, followed thorough optimization strategy. revealed 36 source areas (ESAs) within City, encompassing total area 5807.90 km², predominantly situated in western northern regions. Additionally, 98 corridors (ECs) were identified, extending over 2500.55 km, alongside 100 pinch points (EPPs) 146 barrier (EBPs). city also contains 57 nodes (RNs),, which display distribution characterized “dense east, sparse west” pattern. Furthermore, 165 (RCs) extracted, covering distance 3795.21 km. Based on matrix, was categorized into eight zones: core zone, important eco-recreation key secondary elastic zone.The identified 95 475 sub-strategic. multifunctional complex constructed, “one core, five districts, six corridors, seven wedges”, tailored planning strategy proposed. research contributes theoretical framework construction supports coordinated high-quality activities environments.

Basin Ecological Zoning Based on Supply–Demand Assessment and Matching of Green Infrastructure: A Case Study of the Jialing River Basin

Forests, Journal Year: 2025, Volume and Issue: 16(4), P. 561 - 561

Published: March 24, 2025

Intensive anthropogenic disturbances have driven significant spatial disparities and progressive fragmentation of forest-based green infrastructure (GI) that delivers vital ecosystem services across river basins. To address these challenges, delineating ecological management zones developing spatially targeted GI optimization measures are imperative for safeguarding regional security advancing nature-based solutions in coupled human–water–forest systems. Focused on the mainstream area Jialing River Basin, we establish an zoning system reconciles forest resilience with development equity. By using morphological pattern analysis, landscape analysis In-VEST model, supply capacity was assessed from three dimensions: element composition, structural configuration, services. The demand intensity evaluated based environmental governance pressure, urban expansion social needs counties. Supply–demand matching analyzed quadrant-based mismatch typology coupling coordination degree model. results reveal following: (1) supply-deficit counties predominantly located middle lower reaches basin, characterized by high urbanization economic development; (2) supply-surplus high-level balanced cluster ecologically conserved upper reaches; (3) low-level concentrated agricultural zones; (4) overall show a preliminary state coordination. Based findings, basin classified into five at county level: restoration, management, rehabilitation, enhancement, conservation. Tailored policies were formulated each zone to advance sustainable development.

Ecological security is integral to national strategies, making the construction of ecological patterns essential for mitigating risks. However, predictive research on (ESPs) remains limited. This study integrates Patch-generating Land Use Simulation (PLUS) model with pattern analysis provide scientific insights into spatial governance and optimization in Poyang Lake Economic Zone (PLEEZ). First, PLUS simulated land use changes 2030 under three scenarios: natural development (ND), economic (ED), protection (EP). Based these projections, were constructed using Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model, Morphological Spatial Pattern Analysis (MSPA) method, Conefor 2.6, Minimum Cumulative Resistance (MCR) resistance theory. The results indicate: (1) 19, 18, 21 source areas identified different scenarios, covering 6093.16 km2, 5973.21 6702.56 respectively, 9, 8, 10 important sites, primarily north.
