Ecological restoration of coastal salt marsh

CNKI and Web of Science databases were subject to analysis with information visualization softwares (Cite Space and VOS viewer), for comprehensive analysis of current degradation and restoration research status．Current restoration was found mostly concentrated on single elements of water, soil, and biology, as reflected by habitat restoration and biological population conservation．The use in recent years of system self-organizing process under environment-organisms interaction at multiple spatiotemporal scales to achieve restoration theoretically and in practical application at ecosystem level has gradually attracted attention．Artificial intervention by landscape pattern adjustment in the early stage of self-organizing pattern formation could take full advantage of restoration technology at different spatial and temporal scales．Protection, restoration, regulation and monitoring to maintain system stability under the influence of multiple stresses is important for the protection and restoration of coastal salt marsh．
