The wetland ecosystem is one of the most important carbon sinks on Earth, biodiverse ecological landscape in nature, and living environments for human beings. Weihe River located Guanzhong Plain urban agglomeration, with extreme climate expansion having a great impact its dynamic changes. Revealing characteristics trends dynamics Basin key to protecting maintaining healthy development wetlands. This paper analyzed changing land use types patterns wetlands using data from six periods 1980 2020 explored spatial temporal distribution changes Basin. results showed following: (1) Wetlands Basin, dominated by rivers, saw area fluctuations an initial decline followed increase. Land slow–fast–slow trend. (2) From 2020, frequent conversions among were observed. primary transformation was conversion marshes into lakes (18.05 km2) reservoirs/ponds (17.98 km2). Approximately 0.06 km2 transformed canals/channels. (3) patches have largest area, while canals/channels smallest. patch density (PD) shape index (LSI) fluctuate significantly, reduction leads 3.46% decrease aggregation (AI). Shannon’s diversity (SHDI) has decreased 5.41%. (4) centroid experiences significant changes, river are complex. along southeast–northwest line. Canals/watercourses remain stable.

Ecological Indicators, Год журнала: 2024, Номер 166, С. 112315 - 112315

Опубликована: Июль 1, 2024

High-intensity land development has led to numerous ecological problems, severely threatening regional sustainable development. Resilience is key maintaining This study focuses on the Taohe River Basin and constructs an resilience evaluation model based framework of ecosystem adaptability, resistance, recovery from perspective resilient functions. Using software such as InVEST Fragstats, assesses spatiotemporal changes in Basin. Based pattern, sources were identified, resistance surfaces constructed, corridors extracted, thereby establishing security pattern for During period, level showed a gradual upward trend. A total 33 source areas accounting 27.57 % area Seventy with length 6478.63 km average 92.55 km. Combining topography, background conditions, current urban status Basin, "two screens, two corridors, five areas, multiple points" was along corresponding optimization suggestions. The research results are great significance optimizing spatial layout, security, promoting integrated Additionally, they provide new ideas assessing resilience.

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.

A Study of the Spatiotemporal Evolution Patterns and Coupling Coordination between Ecosystem Service Values and Habitat Quality in Diverse Scenarios: The Case of Chengdu Metropolitan Area, China

Sustainability, Год журнала: 2024, Номер 16(9), С. 3741 - 3741

Опубликована: Апрель 29, 2024

The global ecological decline resulting from urban development presents a significant challenge for numerous regions striving to reconcile conservation efforts with developmental needs. This study explores the relationship between ecosystem service value (ESV) and habitat quality (HQ) under various scenarios elucidate prospective trajectories. utilized PLUS model simulate land use patterns in Chengdu metropolitan area across four distinct scenarios. Furthermore, it employed equivalent factor method Invest quantify ESV HQ values, investigated coupling coordination each city using (CCM). findings are as follows: (1) Between 2000 2020, primarily expanded through of construction land. (2) Concurrently, demonstrated fluctuating trend characterized by an initial succeeded upsurge, culminating Development–Ecological Balance Scenario. Likewise, displayed similar pattern increase, reaching its zenith Ecological Dominance (3) exhibited variability cities Ultimately, this offers distinctive perspective on evaluating interplay conservation, providing valuable insights promoting sustainable other regions.

Global challenges such as climate change, ecological imbalance, and resource scarcity are closely related with land-use change. Arid land, which is 41% of the global land area, has fragile ecology limited water resources. To ensure food security, resilience, sustainable use resources, there a need for multi-scenario analysis change in arid regions. carry this out, multiple spatial techniques indicators were used to analyze typical inland river basin Northwest China—the Tailan River Basin (TRB). Then, PLUS model was analyze, certain time period (1980–2060), same basin. The scenarios included Natural Increase Scenario (NIS), Food Security (FSS), Economic Development (EDS), Water Protection (WPS), Ecological (EPS), Balanced Eco-economy (BES). results show that 1980–2020, TRB mainly driven by changes cultivated grassland, forest built-up land.

Опубликована: Апрель 11, 2025

Water and sediment fluxes into the sea are basis for stability of ecological pattern Yellow River Delta (YRD). As a Ramsar wetland international importance, YRD is facing huge risk land degradation due to changes in water–sediment sea. In this study, we investigated spatiotemporal dynamics coastline subaerial delta using annual remote sensing images revealed more detailed clear relationships between evolution, including whole its subregions (e.g., Qingshuigou Diaokou regions) from 1976 2022. Our results showed that mean yearly water during study period amounted 210.50 × 108 m3 yr−1 367.81 Mt yr−1, respectively. There was an abrupt change 1999, both decreased significantly whereas discharge has increased flux stabilized since around 2000. The area evolutions region can be characterized by three stages: rapid growth stage (1976–1993), retreat (1993–2002), gradual recovery (2002–2022). displayed continuous decreasing trend regression analysis indicated cumulative accretion presented differentiation. with 1992, 1993 2002, except northeast Qingshuigou, then expanded 2003 2022, southeast Qingshuigou.
