“…At present, the influence of typhoons on the ocean was studied almost by the satellite remote sensing data (Chen & Tang, 2012; Iwasaki, 2020; Li et al., 2020; Liu, Jin & Yan, 2020; Liu, Li, et al., 2020; Subrahmanyam et al., 2002; Zhang et al., 2020; Zhao & Wang, 2019; Zheng & Tang, 2007). Since topography and the radiation from land have a great impact on the satellite remote sensing data (Trenberth & Solomon, 1994; Wang et al., 2017), researches about the impact of typhoons on the ocean mainly focus on the open ocean, and researches about the coastal area are very rare (Herbeck et al., 2011; Kao & Liu, 1997; Lin et al., 2019; Shiah et al., 2000). Thus, recently great progress has been made in the influence of typhoons on the open ocean.…”

“…Quanzhou Bay is located in southeast Fujian Province, China, with a flat tidal area of 89.8 km 2 ( Lin et al, 2019 ), and is a typical estuarine ecosystem with two rivers (Jinjiang River and Luoyangjiang River) run into the bay ( Supplementary Figure 1 ). It is reported that Quanzhou Bay has the largest number of pollutant load in the estuaries of Fujian Province, with relatively high concentration of N and P ( Cui et al, 2011 ).…”

Molecular methods revealed that the majority of microbes in natural environments remains uncultivated. To fully understand the physiological and metabolic characteristics of microbes, however, culturing is still critical for microbial studies. Here, we used bacterial community analysis and four culture media, namely, traditional marine broth 2216 (MB), water extracted matter (WEM), methanol extracted matter (MEM), and starch casein agar (SCA), to investigate the diversity of cultivated bacteria in coastal sediments. A total of 1,036 isolates were obtained in pure culture, and they were classified into five groups, namely, Alphaproteobacteria (52.51%), Gammaproteobacteria (23.26%), Actinobacteria (13.32%), Firmicutes, and Bacteroidetes. Compared to other three media, WEM recovered a high diversity of actinobacteria (42 of 63 genotypes), with Micromonospora and Streptomyces as the most cultivated genera. Amplicon sequencing of the bacterial 16S ribosomal RNA (rRNA) gene V3–V4 fragment revealed eight dominant groups, Alphaproteobacteria (12.81%), Gammaproteobacteria (20.07%), Deltaproteobacteria (12.95%), Chloroflexi (13.09%), Bacteroidetes (8.28%), Actinobacteria (7.34%), Cyanobacteria (6.20%), and Acidobacteria (5.71%). The dominant members affiliated to Actinobacteria belonged to “Candidatus Actinomarinales,” “Candidatus Microtrichales,” and Nitriliruptorales. The cultivated actinobacteria accounted for a small proportion (<5%) compared to the actinobacterial community, which supported that the majority of actinobacteria are still waiting for cultivation. Our study concluded that WEM could be a useful and simple culture medium that enhanced the recovery of culturable actinobacteria from coastal sediments.

“…Except for extreme weather conditions, the natural evolution of urban coastal zones tends to remain stable (Lin, 2020;Sun and Niu, 2021). Under the influence of extreme weather, e.g., typhoons and floods, the sediment particle input increases greatly in a short time, whereas the change in hydrodynamics during typhoons causes sediment resuspension and redistribution that affects the evolution of underwater topography (Lin et al, 2019).…”

“…The permanent population of the region was 8.78 × 10 6 in 2020 (data from Quanzhou Statistical Information Network, 2021). The sediments of Quanzhou Bay are primarily derived from the Jinjiang River, of which the annual sediment flux is 2.54 × 10 6 t (Lin et al, 2019). The sediment types in the bay were dominated by silt and clay, whereas the sand content was relatively low.…”

Owing to the development of the social economy, the geographical environment and ocean utilization patterns of urban coastal zones have changed. This change, in turn, has influenced the socio-economic development of urban coastal zones. Based on the Geographic Information System technology, the area, coastline length, and shoreland use function of reclamation areas were obtained from the geographic charts (1954–2020) and remote sensing data (1988–2017) of Quanzhou Bay. In this study, we analyzed the geomorphologic change process and the relationship between land use patterns and economic development in Quanzhou Bay from the perspectives of hydrodynamics, sediments, and human activity. Our results indicated that over the past 70 years, the bay area has reduced by 21.5%. The length of the coastline decreased from 208.36 km in 1959 to 149.11 km in 1988, whereas the shape index of the bay (SIB) decreased from 3.09 to 2.41 during the same period. Between 1988 and 2017, the coastline increased to 162.91 km, causing the SIB to increase to 2.72. The artificial index of the bay increased from 0.28 in 1959 to 0.90 in 2017. The intensity of bay the development (IBD) first increased from 0.27 in 1959 to 0.77 in 2006. During the transition to a more modern society (2006 to present), the IBD slightly decreased to 0.73 in 2017. Affected by human activity, the transformation of the reclaimed land in Quanzhou Bay can be divided into four stages that are closely linked to the economic development in the region. In the early industrialization period, reclaimed land in the region was used for agricultural production, whereas in the mid-industrialization period, it was gradually transformed into a combination of industrial (29.8%) and agricultural (56.1%) lands. In the later period of industrialization, the reclaimed land was gradually converted into urban industrial and port lands. Finally, with further refinement and upgrading of economic and industrial structures, the socio-economic and environmental benefits from coastal reclamation projects have been increasing, whereas the proportion of economic benefits (in the total benefits) has been decreasing. The results of this study can provide decision-making references for the optimization of utilization patterns and the economic development of reclamation lands in coastal areas.
