“…The high biomass values predominantly occur during the early spring seaso with cryptophytes and dinoflagellates being the primary algae from September to Dece ber [22]. The primary sediment type is clayed silt, and the amount of soil C stored in t 100 cm soil profile was 93.10 ± 11.28 kg C m −2 [23].…”

“…The high biomass values predominantly occur during the early spring season, with cryptophytes and dinoflagellates being the primary algae from September to December [22]. The primary sediment type is clayed silt, and the amount of soil C stored in the 100 cm soil profile was 93.10 ± 11.28 kg C m −2 [23]. The water temperature ranges from 21.5 °C to 31.8 °C in summer, and ranges fro 16.1 °C to 19.0 °C in winter, with salinity adjacent to the mangrove wetland, ranging fro 12 to 26 [21,22].…”

The decomposition of mangrove litter plays a crucial role in material circulation and energy flow within mangrove forests. Evaluating the decomposition-based variation in biogenic elements in litter is important for improving our understanding about their biogeochemical cycling in ecosystems. The main objective of this study was to examine the interaction effect during the decomposition process of mixed Kandelia obovata and Avicennia marina litter. Variations in C and N were also determined in the decomposing leaf litter mixtures. Our findings revealed that the decomposition rates were faster in summer than in winter, and increased with the proportion of A. marina litter. After 35 days of decomposition in summer, the remaining weights for different proportions of K. obovata (KO) and A. marina (AM) were 22.9% (KO:AM = 1:2), 27.2% (KO:AM = 1:1), and 31.2% (KO:AM = 2:1), respectively. Similarly, after 49 days of decomposition in winter, the remaining weights for the different KO:AM proportions were 27.7%, 35.4%, and 44.0%, respectively. Additionally, the decomposition of mixed K. obovata and A. marina litter had an influence on C content and N release dynamics. These results provide a scientific basis for understanding the decomposition of mixed mangrove litter and its implications for material circulation and energy flow within these ecosystems.

“…Sun et al [25] investigated the changes in SOC under the invasion of Spartina alterniflora (S. alterniflora) in mangroves, revealing that the invasion increases the rate of SOC decomposition, thereby hindering its accumulation. Similarly, Wang et al [26] examined SOC content changes during the afforestation of mangroves in tidal flats, demonstrating a significant increase in SOC content after the tidal flats evolved into mangroves. Ebrahem et al [27] evaluated the impact of land use change on SOC caused by the conversion of mangroves into shrimp ponds.…”

In order to study the distribution characteristics of soil organic carbon (SOC) and soil organic carbon storage (SOCS) among different wetland types in Dandou Sea tidal wetland in Guangxi, firstly, based on Sentinel–2 imaging and random forest algorithm, combined with the existing tidal wetland data, a 10 m resolution tidal wetland dataset in Guangxi from 2019 to 2023 was generated, covering mangroves, salt marshes and tidal flats. The results show that the overall accuracy of the recognition results is higher than 96%, and the Kappa coefficient is higher than 0.95, which indicates high accuracy. Subsequently, the distribution characteristics and influencing factors of SOC and SOCS in different habitats were analyzed. The results showed that the SOC content of mangroves and salt marshes was higher than that of tidal flats. The SOC content of mangrove, salt marshes and tidal flats in 0–60 cm soil layer was 5.30–10.42 g/kg, 7.60–9.84 g/kg, and 1.29–2.25 g/kg, respectively. The changes of SOCS were 12.41–26.48 t/ha, 19.58–24.15 t/ha, and 3.61–6.86 t/ha, respectively. With the increase of soil depth, the SOC and SOCS of mangroves decreased gradually, and the SOC and SOCS of salt marshes increased gradually, and SOC and SOCS were mainly affected by soil bulk density (BD), soil moisture content (MC) and pH.
