Rapid urbanization has greatly altered urban ecological spaces and habitat quality functions, threatening regional biodiversity the sustainability of landscapes. Therefore, constructing a comprehensive network safety patterns is crucial for ecosystem management development. However, simple quantification networks fails to meet construction needs patterns, most studies focus solely on analysis, thus overlooking importance spatial analysis. This study proposes method assessment combined with hotspot analysis coupled standard deviational ellipse which not only satisfies quantitative but also adds methods, facilitating more patterns. Firstly, through morphological pattern (MSPA) landscape connectivity indices, source areas in main area Kunming were identified, integrating various resistance factors corrective construct an surface. The minimum cumulative (MCR) model was used identify potential corridors, their evaluated using gravity model, establishing network. Secondly, based structure assessed optimized.

This study focuses on the ecological security of Guangxi–Vietnam karst border region, introducing an innovative framework that integrates traditional knowledge (TEK) with modern GIS-based modeling to promote sustainable development. Using remote sensing, geographic information systems (GIS), and sensitivity assessments, this research identifies key sources, corridors, pinch points, barriers. Unlike conventional approaches rely solely biophysical indicators, incorporates TEK-derived practices into network optimization, ensuring conservation strategies align local cultural sustainability. Ecological was evaluated through indicators such as soil erosion, rocky desertification, geological disaster risks guide optimization networks. TEK practices, including afforestation, rotational farming, biodiversity conservation, were systematically integrated construction “three axes, two belts, six zones” pattern. The results revealed 55 80 14 barriers, primarily located in areas high human activity intensity. advances planning by demonstrating a replicable model for TEK-based transboundary landscapes. By integrating methodologies, it enhances ecosystem connectivity, resilience. proposed provides actionable insights urban–rural coordination restoration landscapes, contributing long-term sustainability ecologically vulnerable culturally diverse regions.
