“…(3). Focus on GHG emissions from vegetation maintenance processes Scientific conservation is crucial to carbon reduction in constructed wetlands; for example, some studies have shown that reeds have a significant contribution to GHG emissions from constructed wetlands [83], which may be related to the decomposition of reed root secretions and plant death residues [84,85], and that reeds planted in wetlands with long-term flooded areas are prone to anoxic rotting, and their CH4 emissions can reach up to 15 times that of unplanted reed wetlands [86,87], whereas with proper maintenance, GHG emissions from artificial reed wetlands can be significantly reduced from 160 mg/m 2 /d~400 mg/m 2 /d to 16 mg/m 2 /d~112 mg/m 2 /d [84].…”

The enhancement of carbon sequestration and emissions reduction has emerged as a primary concern in China’s rural regions. Nevertheless, numerous completed rural wastewater treatment facilities necessitate retrofitting due to suboptimal operational conditions. Consequently, evaluating the greenhouse gas (GHG) emissions impact and carbon reduction advantages of rural wastewater treatment facility retrofitting is essential. Existing research predominantly focuses on urban wastewater treatment plants, with minimal attention given to GHG emissions impact during the construction and demolition stages of wastewater treatment facilities. In this investigation, we developed a life cycle assessment (LCA)-based evaluation model to appraise the GHG emissions impact and carbon reduction benefits of retrofitting rural wastewater treatment facilities. We examined a renovation project in Sanxiushan Village, Xiamen City, Fujian Province, incorporating the integrated plant treatment technology of constructed wetlands. Our findings indicate that retrofitting offers significant advantages in terms of GHG emissions reduction, even when accounting for implicit GHG emissions. The establishment of supplementary terraced constructed wetlands and landscape greening can yield more substantial carbon reduction benefits. Moreover, we discovered that implicit GHG emissions during the construction stage can be mitigated by employing local, recycled, and low-carbon materials. Modifying vegetation community structure and prioritizing vegetation species selection can enhance the carbon storage capacity of plants, reducing overall life cycle GHG emissions and augmenting emissions reduction benefits. The evaluation model developed in this study can facilitate the promotion of low-carbon construction and operation of rural wastewater treatment facilities.

“…The Yangtze Estuary is the largest in Asia and is one of the most globally important ecotones (Chen et al, 2012) that provides vital ecological services, including breeding grounds for aquatic organisms and stopover and overwintering sites for millions of migratory birds (Xu and Zhao, 2005). However, it is affected by rising sea-level and anthropogenic pressures that have culminated over centuries of overexploitation, reclamation, and pollution (He et al, 2011;Kirwan and Megonigal, 2013;Liu et al, 2016b;Yu et al, 2018); consequently, eutrophication and reduction in biodiversity have led to a deterioration in the ecological health of the Yangtze Estuary (Chai et al, 2006;Chen et al, 2012;Huang et al, 2021;Huang et al, 2022). In response, an oyster reef restoration project was initiated in the region (Quan et al, 2009), based on previous studies that showed the construction of artificial oyster reefs in the Yangtze River estuary was feasible and effective in the restoration of the ecosystem (Quan et al, 2009;Quan et al, 2012;Lv et al, 2016a;Liu et al, 2018b).…”

The functional groups and the ecological health of a constructed oyster reef were investigated during April 2016 to October 2017 in the Yangtze estuary. The data of the long-term monitoring program (14 years) confirmed the feasibility of creating an artificial oyster reef in Yangtze estuary. One or two functional groups were absent from moderate salinity conditions (5.17% - 8.73%), while macrobenthos functional group species richness, abundance, and biomass were greatest under high salinity conditions. The feeding evenness index (jFD) showed that 14 years after construction, the ecosystem health of the artificial oyster reefs were good or high, and was better under high salinity conditions. Ecological health was lower under moderate levels of salinity, possibly due to the absence of some functional groups. Redundancy analysis indicated ecosystem health was associated with changes in salinity and substrate factors. Our study confirmed artificial oyster reef construction is feasible and has a positive effect on estuarine ecosystem health.

The wetland played a crucial role in producing oxygen and purifying the air, so the conservation projects were essential in response to natural and perceived destruction. The farmland restoration project was utilized to repair the southern buffer zone of Jiangsu Yancheng Wetland National Nature Reserve for Rare Birds on the investigation and analysis of migratory birds, soil fauna and crops. In this paper, the five different crops of colza oil, mustard, Chinese cabbage, wheat, barley were planted in the restoration plots, which was eaten by migratory birds overwinter resulting to the low yield of crops. The species and biomass of soil fauna in non-winter (7 species and 98 soil fauna) were more than that in winter (6 species and 54 soil fauna), and the results of restoration plots was more than that in control. The variety and number of migratory birds had a significant improvement (18 species and 164231 migratory birds), which was owed to different crops and soil fauna. This study found that farmland restoration project could significantly improve the ecological environment of wetland, enrich the biodiversity and attract more migratory birds for inhabit.
