Optimizing the habitat quality (HQ) assessment and revealing its nonlinear influence mechanisms, particularly by considering mountain micro-topographic characteristics, are critically important for promoting sustainable development safeguarding ecological environment of cities. Taking Chongqing main city (CMC) as study area, first, Geomorphons algorithm was used to identify positions. On this basis, HQ InVEST model optimized collecting multispectral data from UAV, spatiotemporal change trend analyzed least-squares method. Secondly, hotspot analysis explore differentiation on different land use geomorphological types. Finally, based generalized additive model, dominant influencing factors were determined, their effects analyzed. The results showed following: (1) average CMC an increasing 2000 2020. four mountains two rivers higher, while it lower in central urban area. (2) hotspots mainly distributed parallel areas composed forests, grasslands, waters. heterogeneity at scale manifested that summits always HQ. (3) influenced a range factors, including both natural environmental conditions socio-economic drivers, among which normalized difference vegetation index most factor.

Understanding the impacts of land use/land cover (LULC) changes on ecological processes is essential for addressing biodiversity loss, habitat fragmentation, and climate change. This study analyzes effects LULC quality landscape connectivity in İzmir, Turkey’s third-largest city, using Integrated Valuation Ecosystem Services Trade-offs Habitat Quality (InVEST HQ) model, Conefor 2.6 analysis, Circuitscape 4.0 resistance-based modeling. relies Coordination Information Environment (CORINE) Land Cover data from 1990 to 2018. Findings indicate that artificial surfaces increased by 82.5% (from 19,418 ha 35,443 2018), primarily replacing agricultural (11,721 converted). Despite this expansion, high areas remained relatively stable, though fragmentation intensified, with number patches rising 469 606 2018, average patch size decreasing 394.31 297.39 ha. Connectivity analysis highlighted Mount Nif Urla–Çeşme–Karaburun Peninsula as critical corridors.

Published: April 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.

Introduction As a key indicator to evaluate biodiversity and eco-function, habitat quality shows the value of ecosystem services. The Qinghai–Tibet Plateau occupies highest elevation in global dimension, where regional environment is greatly affected by multiple factors including terrain comprehensively. Methods In present study, InVEST model was employed assess across varying gradients. study observed displacement center gravity under different topographical over past 20 years learn trend changes. Additionally, Geo-detector enhanced explore contribution rate driving topographic positions overall. Results results found following: (1) positively correlated with gradient, mean values increased gradual increase gradient. period between 2000 2020, within area exhibited slight fluctuating spatial distribution characterized higher southeast lower northwest. (2) Among gradients, trends center’s shift were diverse. gradient I went north but V west. gradients II–IV showed an uncertain trend.

The basalt profiles generally exhibit higher metal content pH values compared to volcaniclastic rock profiles, as accumulates metals. over rocks show significantly than those basalt, indicating spatial variability accumulation. Island notably elevated at both western wharf island’s tail, characterized by lithology, human activities further increasing tail. Land use types influence content, abandoned land lower forest dense vegetation organic matter. Principal component analysis reveals that primarily derived natural parent material, first two principal components comprising 59.77% variance. Ecological risk assessment indicates is considered relatively clean, but Pb presents an ecological hazard, 86.54% sites risk.
