Abstract

Coastal zones as critical nodes in the global carbon cycle, the coordinated development of environmental restoration and blue carbon sequestration has become a key pathway for responding climate change. This paper provides a comprehensive review of research on ecological restoration technologies and blue carbon ecosystems in China's coastal zones. Restoration techniques cover physical restoration, chemical restoration, and biological restoration. Physical restoration includes sediment mixing and dredging operations, and the Fixation and Isolation of Pollutants, chemical restoration includes pollutant neutralization and decomposition, biological restoration includes microbial, plant, and animal restoration. Blue carbon ecosystem research is based on typical ecosystem such as mangroves, seagrass beds, and salt marshes, focusing on its current condition of degradation and restoration measures. Research indicates, deep integration of coastal zone ecological restoration and blue carbon conservation, by improving ecosystem environments and enhancing ecosystem carbon fixation efficiency, achieving a double benefit of pollution control and carbon sink enhancement.
