Assessing the impacts of reclamation and invasion on ecological dynamics of coastal wetland vegetation in the Yangtze Estuary from 1985 to 2019:A case study of Chongming Island, China

Journal of Environmental Management, Год журнала: 2025, Номер 376, С. 124505 - 124505

Опубликована: Фев. 15, 2025

The distribution of coastal wetland vegetation is influenced by biological invasions, human reclamations and climate changes, which continually reshape structures. However, limited attention has been given to the impact invasion on native tidal wetlands. This study focuses wetlands Chongming Island, employing a multi-feature dataset combining spectral, phenological, temporal information Google Earth Engine (GEE) platform. Using Random Forest (RF) classification method, we analyzed annual changes examined distinct effects natural anthropogenic factors. research results indicate that: (1) From 1985 2019, total area Island expanded, while decreased due embankment construction island connection projects. (2) dropped its lowest point in 2002 (3812.76 ha), then gradually recovered. (3) Human reclamation was primary driver from 1995. (4) Vegetation Dongtan both factors, whereas Beiliuyao affected expansion S. alterniflor. These findings provide valuable insights into drivers long-term offering essential data theoretical support for sustainable development management Island's ecosystems.

The Simulation of the Wetland Biodiversity Pattern Under Different Land Use Policies on the Sanjiang Plain

Water, Год журнала: 2025, Номер 17(6), С. 859 - 859

Опубликована: Март 17, 2025

Involving wetland protection policies in the simulation of biodiversity pattern has potential to improve accuracy policy-making. In this research, by combining Cellular Automata Markov Model (CA-Markov) for land use change and a Biodiversity Estimation Based on Hydrological Pattern Connectivity (BEHPC), we put forward comprehensive framework that integrates policy stage division, identification characteristics, prediction. This divided conservation implemented study area into three stages: promoting (1995−2005), strengthening (2005–2010), stabilizing (2010–2020). CA-Markov verification confirmed stages’ consistency with actual implementation, indicating its usability. Using data different stages as input model, then predicted 2030 under scenarios. The results showed during 2010–2020 were most beneficial enhancing area, an expected increase about 8% if continued. offers technical scheme references future evaluation wetland-related at regional scale. It also provides guidance optimizing spatial structure providing numerical goals protection.

Biodiversity Dynamics in a Ramsar Wetland: Assessing How Climate and Hydrology Shape the Distribution of Dominant Native and Alien Macrophytes

Plants, Год журнала: 2025, Номер 14(7), С. 1116 - 1116

Опубликована: Апрель 3, 2025

Coastal wetlands provide critical ecological services but are threatened by the human, climatic, and hydrological changes impacting these ecosystems. Several key ecosystem functions rely on aquatic macrophyte plant species. We integrate 10 years of seasonal monitoring data (2014-2024) climatic datasets to assess how environmental variability influences two dominant macrophytes-the invasive non-indigenous Elodea densa Planch. Casp. (Hydrocharitaceae) native Schoenoplectus californicus (C.A.Mey.) Soják-in Chile's first Ramsar site, Carlos Anwandter, a Nature Sanctuary. modeled suitable habitat areas using MaxEnt software with Landsat 8 spectral bands indices as predictive layers. found significant recent decreases in temperature, river flow, water level, nonsignificant shift precipitation. also observed marked spatial temporal fluctuations for both macrophytes. Stepwise regression analyses indicated that expanded increasing temperature over time declined level variability. showed contrasting effects, declining rising levels expanding higher These findings emphasize complexity coastal wetland ecosystems under stress climate change need further research conservation management along migratory flyways such Southeastern Pacific Flyway.

Spatiotemporal lake area changes influenced by climate change over 40 years in the Korean Peninsula

Abstract Water resources in lakes of the Korean Peninsula play a significant role society and ecosystems both South North Korea. This study characterized spatiotemporal changes lake area during dry season (March–May) over last 40 years. The satellite images (Landsat 5–9) were used to derive annual areas 975 from 1984 2023. Our analysis indicated that MNDWI is optimal remote sensing-based index for delineating Peninsula, with an overall accuracy 92.3%. Based on selected index, total seasons have increased 1070.7 km 2 1659.3 2023, mainly due newly constructed dam reservoirs. While detailed vary, we found divergent results based their sizes. large (> 10 ) showed by 0.0473 (0.1%) every year more influences climate change. On contrary, small (≤ decreases 0.0006–0.006 (0.15–0.5%) less influence shows are determined either change or human activity.

Varied hydrological regime of a semi-arid coastal wetland

Journal of Hydrology and Hydromechanics, Год журнала: 2024, Номер 72(2), С. 238 - 251

Опубликована: Май 9, 2024

Abstract Coastal wetlands are transitional ecosystems between land and sea. Participants of citizen science programs have detected frequent floods in wetlands, as well small pools that appear then disappear. Considering it is not clear whether their main hydrologic drivers marine or continental origin, we studied the El Culebrón wetland located Chilean semi-arid zone. strongly influenced by extreme rain events. This also experiences seasonal changes its water stage (WS). A high mean sea level agreed with 41% WS rises. High intensity storm surges coincided 53% peaks. tsunami 2022 impacted WS, another very intense flooded 2015. An apparent diurnal cycle was discarded due to an instrumental artifact. The combination aforementioned factors provided explanation for 91% probable novel mechanism surge influence on formation a sand barrier coastal lagoon As whole, receives varied influences from both mainland, but seems be more dependent freshwater sources.
