基于CiteSpace分析的海洋生态系统服务研究热点变化与动向

Hotspots and trends of marine ecosystem services based on CiteSpace

海洋生态系统服务作为一个新兴的研究领域,目前仍未形成统一的分类和评估体系,厘清海洋生态系统服务演变趋势,对海洋可持续管理具有重要意义。本研究从分类、内涵、价值评估和管理应用4个方面揭示国内外海洋生态系统服务研究历程,分析其研究前沿与趋势。结果表明,海洋生态系统服务研究热点起初以中小尺度范围典型生态系统的海洋生物多样性保护为主,而后关注海洋生态过程与服务表现的动态变化、关联特征与定量关系,再逐步转向海洋生态系统服务综合评估模型的研究,现正朝着生态系统服务制图、海洋国土空间规划、生态系统管理决策制定的方向发展。海洋生态系统服务从早期参照陆域生态系统服务常规范式,发展至今已逐渐建立符合海洋特色的分类体系和评估方法,未来亟需加强的研究方向包括海洋生态系统服务流研究、海洋生态系统内供需关系研究和海洋生态系统间权衡与协同关系研究等。

As an emerging research field,marine ecosystem service has not yet formed a unified classification and evaluation system.It is vitally significant to clarify the evolution trend of marine ecosystem service for sustainable marine management.The research process of marine ecosystem service at home and abroad was revealed from four aspects:classification,connotation,value evaluation and management application,and its research frontier and trend were analyzed.The results demonstrated that the research hotpot of marine ecosystem service initially focuses on the protection of marine biodiversity of typical ecosystems in small and medium scale,then highlights the dynamic changes,correlation characteristics and quantitative relationship between marine ecological processes and service performance.Subsequently,it gradually turns to the research of comprehensive assessment model of marine ecosystem service,and it is now developing towards the direction of ecosystem service mapping,marine space planning and decision-making of ecosystem management.Marine ecosystem service has developed from referring to the conventional paradigm of terrestrial ecosystem service to gradually establishing classification systems and assessment methods that conform to marine characteristics.The research directions that need to be strengthened in the future include the study of marine ecosystem service flow,the supply-demand relationship in marine ecosystem,and the trade-off and synergy relationship among marine ecosystem.
