However, in the past, due to people's lack of understanding of wetlands, there were some unreasonable construction and management, which caused degradation characteristics such as shrinking wetland area and declining vegetation, which caused a series of serious ecological and environmental problems. According to the results of the second national wetland resources survey, the total area of wetlands in the country is 5360260,000 hectares, compared with the same caliber in the first survey, the wetland area decreased by 339630,000 hectares.
Wetland degradation not only affects its functions such as biodiversity maintenance and water purification, but also affects its carbon sink function. Some studies have found that wetland degradation leads to microbial decomposition and enhanced carbon emissions, which in turn leads to the loss of soil organic carbon. After the degradation of Ruoergai wetland in Sichuan Province to grassland, the soil organic carbon storage was lost by 4 t hm. Therefore, it is of great significance to implement the national-scale wetland carbon sink enhancement plan, further promote wetland ecological restoration, and improve the carbon sink function of wetland ecosystems such as peatlands, coastal salt marshes, and mangroves, so as to alleviate global climate change and achieve China's "double carbon" goal.
