“…Part of each sample was analyzed for organic carbon (TOC) and total nitrogen (TN) content. The sample was treated with 2M HCl solution to remove inorganic carbon, and then washed with puri ed water and dried for determination using an elemental analyzer (Elementar Vario MICRO cube, Germany) (Jiang et al 2022).…”

“…The invasion of Spartina alterniflora led to moderate and even serious disturbances in the macrobenthos community. In addition, the invasion of Spartina alterniflora increased the complexity of the macrobenthos food web in the initial stages of the invasion, and with the prolongation of the invasion, the complexity of the food web decreased [58]. In conclusion, the invasive ability of Spartina alterniflora should be scientifically assessed in relation to the growth conditions in the local area, and appropriate conservation measures should be taken.…”

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.

“…This not only disrupts wetland vegetation habitats but also poses a threat to the survival of intertidal organisms, thereby undermining the stability of wetland ecosystems (Chen et al., 2004; Wan et al., 2014). In recent years, S. alterniflora , listed as one of the invasive alien species in China, has been expanding in coastal areas of China, causing serious ecological problems (Jiang et al., 2022; Wang et al., 2006). The coastal zone of Guangxi is suffering from the expansion of S. alterniflora for its mild climatic conditions and wide tidal flat area, which provide a relatively suitable environment for the growth of S. alterniflora (Wu & Fang, 2005).…”

In recent years, the continuous expansion of Spartina alterniflora (S. alterniflora) has caused serious damage to coastal wetland ecosystem. Mapping the coverage of S. alterniflora by remote sensing and analyzing its growth pattern pose great importance in controlling the expansion and maintaining the biodiversity of coastal wetlands in Guangxi. This study aimed to use harmonic regression to fit time series data of vegetation indices based on Landsat images, and the phenological features were extracted as the input of random forest model to distinguish S. alterniflora in coastal zone of Guangxi from 2009 to 2020. The influence of natural environmental factors on the distribution of S. alterniflora was evaluated by Maxent model, and the potential distribution was analyzed. The results showed that: (1) Based on the time series data of characteristic indices fitted by harmonic regression, the extraction of phenological features of S. alterniflora identification effect exhibited high accuracy (in the result of 2009, Overall Accuracy [OA] = 97.33%, Kappa = 0.95). (2) During 2009–2020, the S. alterniflora in coastal zone of Guangxi kept proliferating and expanding from east to west. The total area of S. alterniflora continued to increase while the growth rate showed a trend that increased first and then decreased. (3) The Maxent model shows good accuracy in simulating the habitat of S. alterniflora, with a potential distribution area of 14,303.39 hm2. The findings will be beneficial to the understanding of dynamic changes of S. alterniflora in coastal zone of Guangxi and provide a scientific reference for other coastal wetland studies on S. alterniflora expansion.
