Resource-intensive cities face significant ecological challenges due to mining activities, which degrade landscapes, pollute ecosystems, and disrupt security patterns. This study proposes a process for identifying patterns (ESP) in cities, integrating landscape risk assessment, remote sensing quality evaluation, district spatial data. We introduce the source index (ECSI) identify sources Chenzhou construct an resistance surface (ERS) by incorporating locations. Using circuit theory, we map key corridors nodes, establishing framework Chenzhou. Our findings show 2,903 km² of primary sources, 1,735 secondary ES, 2,124 tertiary along with 90 (1,183.66 km), 22 inactive (983.37 3 major river corridors, 68 pinch points, 80 barriers.

This study focuses on the Xiaoxing’an Mountains, examining evolution of ecological security patterns and suggesting optimization strategies by integrating carbon storage landscape connectivity, using multi-source data from 2000, 2010, 2020. The provides a comprehensive assessment region’s estimating stocks InVEST model, analyzing connectivity through MSPA, spatially extracting corridors nodes circuit theory. key findings are as follows: (1) High-value areas for primarily concentrated in southeastern northwestern forested mountain regions; (2) Ecological source predominantly southeast dispersed north, with total area peaking 2010 at 47,054.10 km2; (3) Northern dense, radiating spider-web pattern, pinch points corridor termini; sparse, mainly short, fewer points; (4) barriers increased 280% over past 20 years. Four major barrier zones were identified, all located junction forest farmland northwest, composed wetlands, drylands, rural residential areas; (5) Based evolutionary characteristics Security Pattern years, an “axis, two belts, four zones, multiple cores” planning framework was proposed, along corresponding strategies. theoretical support practical guidance enhancing regional network stability, optimizing strengthening sink functions.
