“…Among wetland areas, estuarine wetland soils, due to their location at the river–ocean interface, have a particularly large potential to act as sediment sinks, thus accumulating C (Bianchi et al, ; Burden, Garbutt, Evans, Jones, & Cooper, ; Mitsch et al, ). In this context, the changes occurred in the last decades in China coastal wetlands, such as the reduction in area because of sea level rise (Wang, Wang, Sardans, Tong, et al, ) and land use change (Wang et al, ) are especially important. Despite this reduction, coastal wetlands in China currently still cover 5.80 × 10 4 km 2 (Wetland China, ) and provide many ecosystem services and products (Liu, Zeng, & Chen, ; Wang, Wang, Sardans, Zeng, et al, ).…”
