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.

In the context of accelerating ecological fragmentation, it is urgent to enhance interconnectivity urban patches form a resilient network (EN). The construction Natural Protected Area (NPA) system proposed in 2019 latest strategy implemented by China protecting spaces. However, effectiveness this has not been adequately demonstrated. This study specifically analyzes concrete impacts natural protected area on resilience networks (ENs). economically developed Urban Agglomeration around Hangzhou Bay (UAHB) was chosen as an example for argumentation. Firstly, we utilized circuit theory construct EN consisting 173 sources and 401 corridors. Secondly, were categorized into three levels based their connectivity values. Finally, dynamic disturbance scenario simulation framework constructed evaluate impact NPA EN. results indicated that: (1) preceding 47% are crucial maintaining EN; (2) Compared with other spaces, NPAs have 38% 1100% greater effect first second-level sources, respectively, while its third-level 118% lower. innovatively investigates differential hierarchical areas unprotected environment.

Climate change and human activities are seriously affecting the ecological level economic development of county-level cities. Mianzhu City is a typical city located within Chengdu-Chongqing Economic Circle Yangtze River Belt. The study selected primary sources by analyzing high-level ecosystem service functions over time, using Morphological Spatial Pattern Analysis (MSPA). Ecological resistance surfaces were constructed natural factors to address risks associated with future urbanization. construction security pattern (ESP) followed source–corridor–node paradigm, incorporating changes in risks. From 2010 2020, values declined overall, significant spatial variations. Human increased ecologically fragile areas, aggravating exposure from climate urban expansion. protection restoration zones identified, nature reserves north southern center as core. In 19 46 corridors distribution “more length short north, less long south”. Additionally, 41 pinch points 16 barrier determined. Considering core areas services lands human-intensive activities, setting up general idea centered on forests, river corridors, artificial landscapes. provides new insights into constructing optimizing ESP, offering crucial references for rapid urbanization planning regions.

Plateau ecological vulnerability areas are experiencing substantial challenges that threaten the integrity of networks (ENs) due to irrational human activities, leading habitat fragmentation and connectivity degradation. The objectives this study focus on understanding structure, connectivity, responses ENs construction land, crucial for maintaining sustainability. Employing circuit theory, Minimum Cumulative Resistance (MCR) model, complex network analysis methods, constructed evolution characteristics analyzed. Geographically Weighted Regression (GWR) model is used explore correlation between land pinch points. number corridors increased by 42, total length was reduced 432.85 km, a reduction 15.25%. proportion highest-level points declined from 0.95% 0.67%, indicating enhanced overall connectivity. Complex showed declining betweenness centrality in eight sources over two periods, partial northern central regions. Correlation interaction regional economic development policies restoration measures networks. In with positive correlations, six conservation were designated maintain existing regions negative seven planned improve through scientific methods. This research provides framework optimizing enhancing plateau areas. It offers significant insights into optimization security pattern practical guidance policymakers planners seeking sustainability resilience.

Balancing socio-economic development with ecological protection amid rapid urbanization is a pressing global issue. The security pattern (ESP) follows the reciprocal relationship between and function to conserve processes, providing an effective approach address this problem. However, most studies have adopted single subjective assignment method for resistance factors, lacking exploration of impact various methods on ESP. Taking Fuzhou metropolitan area as case, study proposes different methods: favorable, moderate, unfavorable. By applying circuit theory, it constructs ESP identifies critical areas restoration. findings show that (1) cumulative threshold increases, corridors expands from 171.36 km2 1439.24 km2, moderate identified optimal approach; (2) significant differences exist in identification key under methods. 26 corridors, spanning total length 41.29 km; (3) cover 2469.79 including 13 patches pinch points, while restoration 14.55 7 barriers 21 breaking points. pinpointing proposing targeted strategies, can facilitate practical efforts, thereby achieving sustainable goal minimizing economic costs maximizing benefits.
