Urbanization has significantly impacted ecological connectivity, making the optimization of networks (ENs) crucial. However, many existing strategies focus on overall network structure and overlook spatial concentration local processes flow (EPF), limiting effectiveness planning. This study proposes a novel EN framework based urban–rural gradient zoning to enhance connectivity from perspective EPF. The divides areas outside core urban zone (CUZ) into fringe (UFZ), interface (UIZ), natural rural (NRZ), applying tailored in each zone. These include increasing corridor redundancy, reducing resistance, expanding width alleviate EPF concentration. Using Jinan, mega-city China’s Yellow River Basin, as case study, this simulated changes over 20 years validated framework’s effectiveness. Optimization validation showed that land low-flow corridors 65% UIZ NRZ 5 km improved by 6.3%, addressing seven pinch points three barrier points. highlights importance optimizing ENs via support sustainable development protection policies.

The rapid development of oasis desert cities adversely affects fragile ecosystems, preventing regional sustainable development. This study investigates the spatiotemporal evolution characteristics and potential quantitative relationship between landscape structure (OLS) ecological risk index (ERI) trend in different scenarios Tiemenguan City, a typical city an arid zone northwestern China, from 1990 to 2020. We calculated ERI thresholds for types, classified levels, examined factors influencing risk. normalized difference vegetation (NDVI) were NDVI ≥ 30% oases, 10% <NDVI < transition zones, ≤ areas. Under government control, transitions cropland, woodland, grassland built-up unused land decreased by 20%, whereas conversions increased 30%. results showed following: (1) area expanded continuously 175.5 km 2 345.3 during 30 years. zones 49.7% 37.9%, respectively. was strongly correlated with OLS. zone-transition zone-desert 0.08–0.085 0.111–0.118, (2) Socioeconomic factors, including infrastructure expansion, population density, GDP, dominant influences, contributing 64% ERI, influence natural such as climate declined. (3) low-ERI areas 3.3% under significantly, slowing growth rate zone. quantitatively evaluated types’ levels analyzed effects dynamic migration on type stability. paper provides systematic research framework assessment various types scientific basis conservation related research.

Ecological networks (ENs) offer a proactive, spatially explicit strategy for safeguarding the integrity, functionality, and sustainability of ecological spaces. With land financial resources increasingly constrained, conventional approaches to expanding spaces are often infeasible. ENs have emerged as robust solution address challenges effectively. This study combined bibliometric analysis with traditional literature review examine keyword co-occurrence in EN-related publications from Web Science Core Collection (1991–2024). The results showed significant increase publication volume identified three main research themes: (i) theoretical foundations ENs, focusing on conceptual frameworks principles; (ii) construction methodologies emphasizing design optimization through tools such graph theory, circuit Minimum Cumulative Resistance model, Patch-generating Land Use Simulation model; (iii) EN ecosystem services, highlighting contributions green infrastructure forest management. evolution frontiers unfolds across distinct stages: establishing (1991–2009), advancing (2010–2021), integrating interdisciplinary (2022–2024). Four future priorities guiding studies include service quantification integration, enhancing climate change adaptation resilience, strengthening socioeconomic integration sustainable development, leveraging collaboration technological innovation.

The Middle Yangtze River Urban Agglomeration, a critical ecological barrier in China, faces escalating pressures from rapid urbanization and climate change, leading to fragmented landscapes degraded ecosystem services. To address the synergistic challenges of protection risk management, this paper takes urban agglomeration middle reaches as study area, obtains source patches through morphological spatial pattern analysis. Based on distribution risky areas, blind zones are cut down by optimizing buffer merging patches. Finally, composite network is constructed circuit theory superimposed dual method. results showed that (1) there 16 area. Six complementary sources four new were obtained zone reduction strategy. percentage reduced 58.4% 39.5%. (2) integrated nodes with 11,366 connecting edges identified. distributed around central Jiuling-Mafushan Mountains, mainly western southern areas Dongting Lake Plain. (3) Primary integration for stability, 75% node failure threshold triggering systemic collapse. proposed strategy “mountain protection–plain control–railway monitoring” consistent China’s territorial planning. By incorporating into conservation framework, provides feasible insights balancing development sustainability ecologically fragile areas.
