Urbanization, driven by rapid economic growth, has resulted in dramatic land use/cover change (LUCC), posing substantial risks to urban ecological security. While constructing networks is a productive strategy for achieving balance between protection and urbanization, the limited research conducted on impacts of LUCC spatial patterns during urbanization poses hindrance scientific construction networks. Therefore, this study focuses Jinan City, an important city situated downstream region Yellow River Basin, China. The utilized simulation approaches, including MSPA, MCR, InVEST model gravity model, investigate analyze City from 2000 2020. A set capturing changes network elements was proposed explore evolutionary characteristics pattern Finally, Geodetector impact mechanism findings indicate that: (1) During last two decades, development witnessed expansion approximately 588.83 km2, proportion also increased, but overall structure distribution are not balanced. (2) Despite areas, escalation resistance significant degradation functional capacity corridors, with decrease 8.37 % number primary corridors. reduced connectivity impeded efficient cycling processes ecosystems. (3) complex interactions cumulative effects led evolution transformation cropland into improved composition network, while encroachment disorderly internal types principal factors causing elements. (4) influenced coupling policies. However, there need government strengthen policy coordination optimize layout better manage conserve This holds potential offer valuable insights references guiding planning, protection, formulation sustainable policies throughout process.

Habitat fragmentation is an important factor affecting biodiversity conservation, and few studies have discussed the relationship between overall pattern of wetlands biological ecological functions. Based on this, this study proposed construction wetland conservation Ecological Networks (ENs) from perspective connectivity, a comprehensive framework for ENs. Firstly, key species were identified, habitat patches suitable egret migration analyzed by Morphological Spatial Pattern Analysis (MSPA) landscape connectivity index, sources determined based policy influence. The Minimum Cumulative Resistance (MCR) model was used to extract ENs, network evaluation gravity Hydrological analysis analyze "network − corridor node" respectively. results showed that: (1) in Haikou City relatively trivial, within insufficient. There 13 potential 17 extraction; (2) ENs tends be east Nandu River, tightness 0.038, low; (3) are 45 corridors 8 sources, mainly concentrated River; (4) Identify 115, 50 66 pinpoints, obstacle points break network, propose protection, optimization restoration strategies Comprehensive identification progressive will promote further systematization protection research.

Construction of Ecological Security Network in Mountainous Transitional Geospace Using Circuit Theory and Morphological Spatial Pattern Analysis: A Case Study of Taihang Mountain Area

Sustainability, Год журнала: 2025, Номер 17(4), С. 1743 - 1743

Since entering the process of industrialization, human activities have interfered with original ecological environment, and expansion cities has also impacted service function. In order to maintain balance ecosystem stability security, it is very important establish an security network (ESN), particularly in transitional geospace. To address this, we proposed a framework for mountainous geospace by morphological spatial pattern analysis circuit theory. Taihang Mountain area applied as case, establishing suitable evaluation system Using theory quantitively construct ESN, was found that there are 34 sources area. The corridors primarily run north–south east west but display mesh-like layout central southern parts. These elements integrated ESN “four zones three lines”. Key pinch point areas plains or plateaus, barrier restoration mainly basins areas. study provides recommendations protection work area, which hold both theoretical practical significance planning.

Spatial–Temporal Evolution of Ecological Network Structure During 1967–2021 in Yongding River Floodplain

Land, Год журнала: 2025, Номер 14(5), С. 930 - 930

Опубликована: Апрель 24, 2025

Constructing a rational ecological network is crucial for balancing regional development with environmental protection. However, existing research typically emphasizes the analysis of overall patterns, lacking an in-depth exploration dynamic changes in key elements and interactions between different components. Using Yongding River floodplain as case study, this study applied morphological spatial pattern analysis, landscape connectivity metrics, biodiversity assessments to identify core source areas. Circuit theory was used delineate corridors analyze evolution across four years, while graph facilitated structural characteristics. Furthermore, areas restoration were identified within floodplain. We found that number patches area has remained relatively stable, though their total shown fluctuating decline, accounting approximately 10% Additionally, have decreased significantly from 1967 2021, marked reduction major corridors, leading increased resistance material energy flow corresponding decline stability. More importantly, current pinch points are primarily distributed bead-like along channel, barriers concentrated northern eastern floodplain, often at intersections dense road networks corridors. These critical fragmentation prioritized targeted protection efforts. Overall, advances our understanding distribution composition river corridor offers framework evaluating these through multidimensional optimization approach patches. At same time, we conducted providing valuable guidance future initiatives

Cities along the lower reaches of Yangtze River (CLRYR) have highlighted human-land conflicts with their rapid urban expansion. Fully assessing landscape ecological risk (LER) region and its response in context urbanization is great significance for regional sustainable development. To address this issue, study explores spatiotemporal evolution LER CLRYR from perspective “production-living-ecological” space (PLES), evaluates decoupling status processes different cities, aiming to provide scientific reference policymakers. The results indicate that mean value increased 0.2508 2000 0.2573 2020, an increase fluctuations. From a spatial distribution perspective, proportion medium highest, consistently above 30%; lowest less than 3%. Moran’s I values were 0.4773, 0.4014, 0.3326, 0.2462, 0.4779, respectively, indicating significant positive correlation.
