Research Progress and Prospects on the Effects of Pollutant Discharge on the Mangrove Carbon Sink:A Case Study of Futian Mangrove Forest
Mangroves play a crucial role in carbon storage and ecosystem services.Understanding the impact of pollutants on the carbon sink functions of mangroves holds immense significance for environmental protection and sustainable development planning.Pollutants,including organic pollutants,heavy metals,nutrients,and microplastics,enter mangroves through river flow,atmospheric sedimentation,and groundwater infiltration.These pollutants influence the carbon storage function of the mangrove ecosystem through three primary mechanisms:the vegetation growth process,sediment properties,and the structure and function of microbial communities and habitat organisms.In this paper,three strategies and measures are proposed to minimize the negative impact of pollutant discharge on the mangrove carbon sink.Firstly,strict control measures should be implemented to regulate the discharge of treated sewage into the mangrove growing sea area.Secondly,careful consideration should be given to the long-term effects of pollutant accumulation in mangroves.Lastly,the development of innovative technologies that promote the synergistic effect of pollution reduction and sink enhancement should be prioritized.These strategies offer a fresh perspective on the long-term protection of the mangrove carbon sink and the overall health of the ecosystem.
