滨海盐沼湿地生态修复研究进展

Ecological restoration of coastal salt marsh

利用CNKI和Web of Science数据库进行检索,结合Cite Space和VOS viewer等信息可视化软件,对国内外滨海盐沼湿地退化及修复研究现状进行系统性分析.研究结果表明,目前滨海盐沼湿地修复多集中在水、土、生等单一要素层面,主要体现在生境修复和生物种群保育2方面,存在修复效果维持时间有限等问题.近些年来,利用环境与生物间多时空尺度交互作用下系统自组织过程机制,实现生态系统层面的修复理论和实践应用逐步引起重视,在自组织斑图形成的早期阶段通过景观格局调整,实施人工干预可以发挥修复技术在不同时空尺度上的优势.全球气候变化和高强度人类活动等多重胁迫影响下,探索面向系统稳定性维持的保护、修复、调控及监测体系成为变化环境下滨海盐沼湿地保护与修复研究的重要方向.

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.
