The study focused on optimizing carbon sequestration in urban artificial wetlands, using the Shanghai Fish and Dishui Lake as case studies. As cities like experienced rapid urbanization, natural wetland areas diminished, making wetlands essential for storage ecosystem preservation. investigated how various factors—such plant species, size, landscape patterns—influenced sequestration. Through field surveys remote sensing, density changes from 2018 to 2023 were analyzed grid-based pattern metrics. Results showed significant spatial variation sequestration, with larger, more fragmented patches contributing storage. Emergent plants, particularly Phragmites australis Typha angustifolia, demonstrated highest potential. research proposed three optimization models (point, linear, planar) tailored different areas, focusing expanding diversity, enhancing complexity, improving patch distribution. After optimization, was projected increase by 2.6 times, while Lake’s expected grow 3.5 times. concluded that carefully planned management, emphasizing species selection design, could significantly enhance Shanghai’s neutrality goals. provided valuable insights ecological planning, highlighting role of climate regulation.

Abstract Background The Zoige Plateau hosts the largest alpine peatland in world, playing a crucial role carbon sequestration and biodiversity conservation. However, this valuable ecosystem has been significantly impacted by anthropogenic drainage for various purposes, prompting increased interests ecological restoration efforts. This study evaluates changes plant diversity, community composition, biomass allocation across natural, drained, rewetted peatlands, with particular focus on variations microtopography, including hollows hummocks. Results Restoration showed higher soil water content, which was 11.6% (to 88.5 ± 0.09%) 14.4% hummocks 81.1 1.6%) of peatlands compared to natural ( p < 0.001). table depth did not differ from that = 0.61).

This study examines the responses of soil organic carbon (SOC) pools and their components to agricultural water drainage in paddy fields, with a focus on wetland–paddy field ecotone Xingkai Lake, transboundary lake shared by China Russia. Field investigations targeted three representative wetland vegetation types: Glyceria spiculosa (G), Phragmites australis (P), Typha orientalis (T), across durations ranging from 0 over 50 years. SOC fractions, including light fraction (LFOC), heavy (HFOC), dissolved (DOC), microbial biomass (MBC), were systematically analyzed. The results revealed that T P wetlands steadily increased duration, whereas those G exhibited fluctuating pattern. dynamics primarily driven LFOC, while MBC displayed species-specific variations. Correlation analyses structural equation modeling (SEM) demonstrated physicochemical properties, such as total nitrogen moisture content, exerted stronger influence fractions than biomass. Overall, drawdown significantly altered dynamics, distinct observed types ages. provides critical data theoretical insights for optimizing sequestration hydrological management systems.
