Rapid urbanization has led to severe fragmentation of ecological spaces in high-density metropolitan regions, threatening urban security and environmental well-being. While cities explore various restoration strategies, the systematic identification priority areas remains an urgent challenge, particularly due limitations multi-scale evaluation methods. This study develops integrated nested-scale analytical approach examine elements at central levels, using Metropolitan Nanjing as a case study. The framework combines Morphological Spatial Pattern Analysis (MSPA), Landscape Connectivity Analysis, INVEST Habitat Quality Assessment identify sources while employing multi-dimensional resistance system Circuit Theory Model for critical node assessment. findings reveal notable spatial overlap between pinch points barrier across scales, demonstrating importance coupling maintaining network stability. Through this analysis, 3297 are identified classified into three hierarchical categories, offering practical optimizing networks regions.

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.

The convolutional neural networks (CNNs) functioning on geometric learning for the urban large-scale 3D meshes are indispensable because of their substantial, complex, and deformed shape constitutions. To address this issue, we proposed a novel Geometry-Aware Multi-Source Sparse-Attention CNN (GeoSparseNet) triangular mesh classification task. GeoSparseNet leverages non-uniformity to depict both broad flat areas finely detailed features by adopting multi-scale kernels. By operating edges prepare subsequent convolutions, our method exploits inherent geodesic connections utilizing Large Kernel Attention (LKA) based Pooling Unpooling layers maintain topology accurate predictions. Learning which in face collapse, establishes task-oriented process where network highlights enhances crucial while eliminating unnecessary ones. Compared previous methods, innovative approach outperforms them significantly directly processing extensive data, resulting more discerning feature maps. We achieved an accuracy rate 87.5% when testing model dataset Australian city Adelaide.
