摘　　要：Mangrove wetlands are among the four most productive tropical and subtropical ecosystems.They are also a core component of the coastal blue carbon ecosystem,which is of great ecological significance to human beings,plants,animals,and the global carbon balance.There has been a global decrease in the distribution of mangrove forests,and their ecological function has gradually degenerated since the Holocene.Sediment from coastal mangrove wetlands can provide records of climate change and human activities,and multiple proxies including palynology,leaf fossil,biomarkers,DNA,phytolith and stable isotopes,can be used to reconstruct the evolutionary stages of paleo-mangroves and to identify the effect of natural processes and human activities on the distribution and evolution of mangroves.This information can provide theoretical support for mangrove protection and for improving carbon sequestration capacity.This paper summarizes and compares the multiple proxies for mangrove reconstruction,reviews progress in the study of natural succession of global mangroves since the Holocene,expands on the influence mechanisms of human activities on mangrove growth and development and uses past information to lay a foundation for a model to predict future mangrove development.
