Rapid and disordered urbanization has created a fragmented landscape, the urban–rural fringe (URF), which led to degradation of ecological connections between urban areas rural hinterlands. The security network (ESN) offers significant advantages for restoring interrupted processes. However, classic ESN construction approaches are ineffective in URF when applied highly complex landscape. In this paper, new approach stepwise is proposed, integrates basic connecting create an optimized ESN. Taking Xiamen as case study, elements were extracted reclassified construction. scarcity transitional patches complexity land cover responsible lack corridors. final consisted 19 source nodes with 7 structural corridors, 22 8 Moreover, performance spatial coverage both significantly improved after optimization. optimal buffer widths structural, connecting, corridors 600 m, 180 120 respectively.

Ecological network construction and optimization is an effective way to balance the contradiction between regional development ecological protection in process of urbanization. The urban–rural fringe both a frontier zone direction urban expansion important space for improving environment. However, there are few studies on how construct optimize networks fringe. In this paper, morphological spatial pattern analysis (MSPA) minimum cumulative resistance model (MCR) were firstly employed initially reveal characteristics problems security study area. Then, new strategy with multi-scenario coupling gradient zoning was proposed meet maximization integrated benefits future protection. results show that: (1) Urbanization caused high fragmentation patches, exerted strong hindrance processes. (2) distribution constructed extremely uneven, communication north–south severely difficult. optimized significantly improved respect, priority corridors will also help strengthen gradient. (3) connectivity accessibility Licheng District, enhanced its structure, which promote overall cycle better balanced (4) Policy makers should implementation green forest belts achieve This can provide scientific references biodiversity conservation, infrastructure planning, sustainable

The ecological network construction and optimization are of great significance in ensuring regional security optimizing the space national territory, therefore constructing spatial proposing countermeasures conducive to enhancing stability. However, current research on networks ignores ecospatial community structure topology characteristics networks, lacks a systematic framework. scope primarily concentrates urban administrative units, with less emphasis geographic scale watersheds. This approach is not comprehensive management all elements ecosystems. Therefore, this took Erhai Lake Basin as an object, adopted Morphological Spatial Pattern Analysis (MSPA) landscape connectivity extract sources, simulate corridors identify weak points through model Minimum Cumulative Resistance (MCR) gravity model, constructed Basin, topologized by using Gephi platform. Based results analysis complex indicators, strategy increasing edges was proposed. Priority conservation areas were further identified, pattern designed, restoration planned. Results show that 28 378 potential corridors, 48 important 86 formed Basin. had clear clustering instability, high degree concentration northeast uneven betweenness centrality, especially higher east. Through analysis, 12 increased edge nodes 9 simulated, 26 added, significantly improving robustness. pattern, strict control around lake, barrier belts priority designed. study implemented based enhance stability network, which provides theoretical basis for useful exploration ecologically fragile watersheds protect environment achieve high-quality sustainable development.

As critical prerequisite for sustainable development research of social ecosystem (SDSE), the relationship between landscape security pattern and services should be explicitly evaluated to support SDSE research. However, existing evaluation system lacking integrating analysts factors led vague knowledge mechanism. To tackle this issue, study, therefore, explored ecological risk (e.g. carbon sequestration, soil conservation, water yield, crop production residential support) at Xi'an Metropolitan Area using remote sensing data in 2010 2020. The results show that overall decreased from 0.2618 0.2479. Although rapid urban leading improvement support, total has declined due decline yield production. Preventing on fragmentation cannot improve level services. Notably, stronger interference human activities overwhelmingly caused a single advantageous with extreme risk, while less multiple regulation medium–low risk. Additionally, competitive would not produce higher by intervention activity. sequestration (or conservation) resulted high Using these results, potential spatial plan is then made based areas This study benefits decision-making regional comprehensive prevention, future planning orientation, ecosystem.
