“…Coastal wetlands (CWs) serve as a gateway between the marine and terrestrial ecosystems [1,2]. Their significance lies in their ability to safeguard coasts, relieve coastal erosion and sea level rise, provide food and contribute to the global economy.…”

“…While these transformations have the potential to generate substantial social and economic advantages, they have also led to the depletion and deterioration of a considerable number of 2 of 13 CWs [6,7]. The land conversions resulted in a significant decline of 53% (from 6463 km 2 to 3036 km 2 ) in CWs in the Yellow Sea area of China between 1984 and 2015, among which there was a 67% decrease in salt marshes and a 49% decrease in beach areas. Furthermore, the rate of land reclamation surpassed the rate of growth of CWs during this period [8].…”

Land use/land cover changes (LULCCs) and biological invasions significantly impact coastal wetlands (CWs) and their ecosystem services and functions. The exact impacts, however, are difficult to quantify and are often neglected in policymaking. The evaluation of ecological service value (ESV) is conducive to clarifying the ecological and environmental changes caused by LULCCs and biological invasions. The objective of this study was to investigate their impact on CWs in Jiangsu Province, China, and provide useful information and advice for policymakers concerned with sustainable development. In this paper, basic data were obtained through geographic information system technology, and CW ecosystems’ services were calculated via the ESV coefficients per unit area of different wetland types. Accordingly, this study found the current land use methods responsible for significant ecosystem disruption and reductions in the area of natural vegetation. Currently, the area of natural vegetation only accounts for 43% of the total area recorded in 1987. In 2018, the total ESV of wetland vegetation (Spartina, Phragmites, and Suaeda) was estimated to be USD 14.10 million, while that of farmland was USD 8.58 million, and that of forests was USD 2.09 million. Natural vegetation only covered 9% of the total land area but produced 60% of the total ESV. Spartina alterniflora exhibited the highest ESV per unit area, with USD 1.35 million. However, the CWs of Jiangsu Province have recently shown a shift in vegetation composition due to the invasion of Spartina alterniflora. Currently, the dominant species in these CWs are Spartina alterniflora and Phragmites australis, while the local population of Suaeda salsa has significantly declined. Therefore, it is necessary to strengthen the preservation and restoration of wetland vegetation, control the invasive potential of Spartina alterniflora, and consider the implementation of suitable protective measures for native plants.

“…Os pulsos de inundação em banhados, marismas e lagoas, decorrentes de inundações sazonais (Simioni, 2017), são característicos da oscilação dos níveis de água em Áreas Úmidas (AUs) e descrevem a sua estrutura e funcionamento. É a força dominante dos processos ecológicos que nelas ocorrem (Ricaurte et al, 2019) e um dos principais processos hidrogeomorfológicos que atuam sobre essas paisagens (Goerl et al, 2012;He et al, 2023;Oliveira, 2021).…”

“…Os eventos do El Niño estão associados a um aumento na extensão da inundação superficial dos corpos de água e alterações no comportamento dos pulsos de inundações das AUs globais (Barros e Albernaz, 2014;Zhu et al, 2017). Ocasionam impactos significativos na dinâmica das AUs, nas suas funções hidrológicas e ecossistêmicas (Ilyas et al, 2019) devido às mudanças nos padrões de precipitação (Rossi e Soares, 2017), que por sua vez podem modificar a estrutura e função destes ambientes (He et al, 2023).…”

Os pulsos de inundação são responsáveis pelos processos e conectividades ecológicos em Áreas Úmidas, e um dos principais processos hidrogeomorfológicos ocorrentes nestes ecossistemas. O Parque Nacional da Lagoa do Peixe, situado na área costeira do extremo sul do Brasil, tem banhados, lagoas e marismas característicos das Áreas Úmidas. Os pulsos de inundação são previsíveis, polimodais, dependentes do regime de precipitação e sofrem influência de eventos associados à variabilidade climática (El Niño Oscilação Sul e Modo Anular do Hemisfério Sul). O objetivo deste trabalho é analisar a variação espaço-temporal dos pulsos de inundação das Áreas Úmidas do Parque Nacional da Lagoa do Peixe, a partir da variabilidade da precipitação e dados de sensoriamento remoto. Para isso estruturamos o trabalho em duas etapas: (i) escolha das imagens de satélite e identificação dos pulsos de inundação, entre 1987 e 2023, contemplando eventos de El Niño, La Niña e Neutro, e (ii) mapeamento das áreas alagadas utilizando imagens de Índice de Diferença de Água Normalizada Modificado. Os resultados mostram a influência de El Niño Oscilação Sul e Modo Anular do Hemisfério Sul nos pulsos de inundação, com maiores áreas alagadas na primavera (2013, 2015, 1998, 1987), em ano de El Niño e em ano Neutro. Em eventos de estiagem, associados a La Niña (2023), normalmente no verão, ocorre a quase total ausência de lâmina de água no sistema lagunar.
