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.

Relationship between ecological spatial network and vegetation carbon use efficiency in the Yellow River Basin, China

GIScience & Remote Sensing, Год журнала: 2024, Номер 61(1)

Vegetation, as a crucial carbon sink, is facing extensive degradation under the mounting pressures of urbanization and excessive resource exploitation, exacerbating imbalance between sources sinks. In response, ecological spatial network has emerged comprehensive conservation strategy to establish maintain connectivity interactions among diverse ecosystems, ensuring continuous provision services preservation biodiversity. A pivotal indicator in this context vegetation use efficiency (CUE), which elucidates relationship CO2 assimilation through photosynthesis biomass growth. study, utilizing remote sensing data, Yellow River Basin (YRB) was selected case study analyze CUE Carnegie Ames Stanford Approach (CASA) Light Use Efficiency-Normalized Difference Water Index (LUE-NDWI) models. Furthermore, Morphological Spatial Pattern Analysis (MSPA) method Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model were employed delineate for woodlands, shrublands, grasslands, while Minimum Cumulative Resistance (MCR) used identify corridors, forming an within YRB. Subsequently, interrelationship topological metrics analyzed, optimization strategies proposed based on significance structure function. The findings revealed that: (1) Vegetation exhibited spatially decreasing trend from western eastern regions, with patterns correlated types, temperature, precipitation distribution; (2) demonstrated denser configuration upper middle reaches sparser shorter pattern lower reaches, seamless all regions; (3) Significant correlations observed CUE, prompting adoption construction protection measures when functional importance deficient, enhancing augmentation corridors structural lacking. implementation these expected bolster functions network, facilitate cycling, exert positive far-reaching impact sustainable development environment

Construction and Analysis of the Ecological Security Pattern in Territorial Space in Shaanxi of the Yellow River Basin, China

Atmosphere, Год журнала: 2025, Номер 16(2), С. 217 - 217

Опубликована: Фев. 14, 2025

In the context of rapid urbanization and extreme climate change globally, balancing ecological resources economic development for land spatial planning has become one pressing issues that need to be addressed. This study proposes a composite model construct security pattern. It identifies restoration areas with different risk levels based on distribution use, offering suggestions optimizing configuration. Focusing central Shaanxi region Yellow River Basin in China, sources are identified by integrating factors, corridors zones extracted using minimum cumulative resistance difference circuit theory. The results indicate significant improvements quality desertification area from 2000 2020. Currently, core covers 51,649.71 km2, accounting 62.18% all landscape types; total source 31,304.88 representing 18.84% entire area. These mainly distributed northern Loess Plateau southern mountainous regions. 26 important corridors, identifying 16 pinch points 12 barriers, presenting an pattern characterized grid-like structure dispersed region. Additionally, 273.72 km2 priority 197.98 square kilometers encouragement proposed as key regions environmental protection. provides references configuration promote sustainable urban rural living environments Basin.

A Prediction–Interaction–Driving Framework for Ecosystem Services Under Climate Change and Human Activities: A Case Study of Zoigê County

Land, Год журнала: 2025, Номер 14(3), С. 441 - 441

Опубликована: Фев. 20, 2025

Under climate change and human activities, ecosystem service (ES) research lacks systematic approaches scientific depth. This study develops a comprehensive framework integrating advanced models to predict ESs, analyze interactions, identify key drivers, assess spatial effects on the Zoigê Plateau. The results indicate following: (1) From 2000 2020 across three 2040 scenarios, water conservation (WC) improves, while carbon storage (CS) habitat quality (HQ) decline, leading overall ES degradation. Core areas face rising degradation risks from 9% 29% under increasing environmental stress (SSP119 SSP585). (2) importance follows HQ > CS SC WC, with bivariate interactions outperforming single-factor effects. Future scenarios show weakened correlating higher ecological stress, indicating stability risks. (3) Land use (>40% explanatory power) is primary driver, urban expansion, slope, evapotranspiration, precipitation contribute (6–12%). (4) drivers showed weak patterns but became more stable future suggesting stronger control. provides methodological paradigm for analysis supports planning in alpine wetland–grassland regions.
